By the way, if you need to jump it, the connection posts are under the hood, passenger side. Here are some of the frequent check engine OBDII fault codes or DTCs (Diagnostic Trouble Code) and their generic meaning. The mass air flow or MAF sensor is placed in the intake air duct between the air filter and the engine intake manifold.
The code P0101 is set when the signal from the mass air flow sensor is out of expected range.
The code P0101 could be caused by problems with the mass air flow sensor itself, or other issues that affect the air flow measurements, including intake leaks, restricted exhaust, etc. A Nissan technical service bulletin (TSB) for the trouble code P0102 in 2002 Nissan Maxima recommends removing debris from inside the air filter housing, replacing the airflow meter assembly and reprogramming the ECM. The air duct between the mass air flow sensor and the engine intake needs to be checked for cracks, tears, loose clamps or improper connection. A: If you don't have a scan tool to test the MAF sensor properly, replacing it could be a good first step. The barometric pressure sensor (BARO) measures the atmospheric pressure that varies with altitude. If there are other trouble codes present along with the P0106, they should be looked at first, as the code P0106 could be set due to other faults.
A Mazda technical service bulletin (TSB) describes a problem with the corrosion at the MAP sensor causing the code P0106 (MAP sensor malfunction) in 4-cylinder models of some 2004-2006 Mazda 3, 2006 Mazda 5, 2006 Mazda MX-5 and 2003-2006 Mazda 6.
A GM TSB describes a problem with some 2006-2009 GM trucks where the condensation may freeze inside the MAP sensor in cold weather causing the code P0106.
If it's a MAP sensor, the signal voltage with the ignition key ON, engine OFF (KOEO) should be around 4-4.9 Volts. With the ignition ON, check the +5 Volts reference voltage with the voltmeter and the ground at the sensor. For example, when the car is started cold, the engine computer compares the data from the engine coolant temperature sensor (ECT) and the intake air temperature sensor (IAT).
The code P0116 could be caused by a bad engine temperature sensor itself, poor connection at the sensor, wiring problem or the problem with the coolant system.
The code P0128 essentially indicates that the specified engine temperature was not reached after the engine was running for a sufficient time.
The code P0150 - O2 Sensor Circuit (Bank 2 Sensor 1) has the same meaning, but it relates to a front oxygen sensor of the bank 2.
The code P0153 - O2 Circuit Slow Response (Bank 2, Sensor 1) has the same meaning, but refers too the front oxygen sensor of the bank 2. If there are other trouble codes stored along with the P0134, they might need to be looked at first.
In some Hyundai V6 engines, a faulty oxygen sensor could cause the code P0134 along with misfiring codes (P030x) and rich condition; replacing the oxygen sensor should solve the problem. A TSB for 2000-2001 Nissan Maxima mentions possible intermittent connection at the ECM causing the code P0134 or others. In some Volkswagen cars, a bad mass air flow sensor could cause a lean condition that could in turn cause the code P0134 along with some other fault codes. The front or upstream oxygen sensor is located in the exhaust manifold or in the exhaust down pipe before the catalytic converter.
P0161 - O2 Sensor Heater Circuit (Bank 2 Sensor 2) work the same way, just for different oxygen sensors. The engine computer (ECM) uses the signal from the rear O2 sensor to monitor the catalytic converter efficiency. The code P0156 O2 Sensor Circuit Malfunction (Bank 2 Sensor 2) has the same meaning, but it relates to the rear oxygen sensor of the bank 2.
The code P0141 woks the same way as P0135, but it's related to the rear O2 sensor (Sensor 2) of the Bank 1.
For example, A technical service bulletin for 1996-99 Honda Civic mentioned the problem where the engine wiring harness is rubbing on the intake manifold bracket in the back of the engine causing the code P0141 along with some other codes and blown fuse. A while ago my 2003 Honda Accord threw the check engine light with the code P0141, I just replaced the rear O2 sensor, cleared the code and the problem was fixed. The code P0155 works the same way as the fault code P0135, but it's related to the front O2 sensor (Sensor 1) of the Bank 2. The code P0161 has the same meaning as the trouble code P0135, only for the rear O2 sensor (Sensor 2) of the Bank 2. The code P0170 means that the air-fuel mixture coming in to the engine is too lean, or too rich. The code P0170 could be caused by a number of reasons, such as vacuum leaks, bad PCV valve, or other parts of crankcase ventilation system, low fuel pressure, bad oxygen sensor, etc.
In some Mercedes-Benz vehicles besides other reasons, a bad mass airflow sensor can cause the code P0170 Fuel Trim Malfunction (Bank 1), as well as P0173 Fuel Trim Malfunction (Bank 2). To find the exact reason in your car, your mechanic may need to check your vehicle for vacuum leaks, test the mass airflow sensor readings with the scan tool, check fuel pressure, as well as few other things. The code P0171 means that the air-fuel mixture coming in to the engine is too lean, or there is too much air and too little fuel.
From my experience, problems with a mass air flow (MAF) sensor are fairly common; sometimes the mass air flow sensor just gets dirty and gives false air flow readings causing lean condition and the code P0171. Step 5Place the new batteries in a lint-free cloth and use the cloth to insert the new batteries under the contact springs with the plus (+) side facing up.
We are still working to obtain content for your car, however the video above is believed to have similar characteristics as your car. The video above shows you the steps needed to check the power steering fluid level in your 2009 Mercedes-Benz C300.


There's no reason to check the washer fluid level without adding some - see how to do it here! Flushing the coolant in your car is not that hard and will extend the life of your engine tremendously - learn how here!
Hold the remote control and look at the edge that you just removed the metal key from (with the wide end up). You will be removing the entire wide end of the remote control from the rest of the control. Use your middle fingernail and thumbnail in the edge of the battery holder and pull up on the battery holder.
This is of course very basic information to give you an idea, as the interpretation of the check engine diagnostic trouble codes varies slightly between different car manufacturers. In this case, a repair manual usually lists which code should be troubleshooted first, as additional codes may be set as a result of the same problem. The engine computer (ECM) uses the mass air flow signal to know the engine load and to calculate the proper amount of fuel injected.
Nissan Maxima, Frontier, Sentra, Pathfinder, as well as Infinity Q30, QX4) the code P0100 could be caused by a bad mass air flow sensor or broken soldering at mass air flow sensor terminals.
As a solution, Nissan recommends cleaning the air filter housing, replacing the mass air flow sensor assembly and installing the original Nissan air filter, as well as checking, and if needed, reprogramming the ECM. The connector and the wiring between the mass air flow sensor and the ECM need to be checked for open or shorts. An air duct between the mass air flow sensor and the engine intake needs to be checked for cracks, tears, loose clamps or improper connection. The connector and the wiring at the mass air flow needs to be checked for loose terminals, corrosion or damage. A mass airflow sensor signal must be checked with a voltmeter or better with a scan tool at different RPMs and compared to the reference chart or values from a known good air flow sensor. The engine computer (ECM) uses the mass air flow signal to calculate the amount of fuel injected (read more how the MAF sensor works below).
The repair involves clearing the code and replacing the MAF sensor if no other problems found. A Toyota TSB describes a problem with 2006 Toyota Tacoma, where loose terminals in the MAF sensor connector could cause the code P0102; the connector must be checked and repaired if needed. If the sensor looks clean and the air filter is OK, the only way to test it is with a scan tool. The MAP sensor measures the absolute pressure inside the engine intake manifold which is directly related to the engine load.
Next, check the signal voltage and see what it reads with the ignition key ON, engine OFF (KOEO) and if it changes when the engine is started. Normally, when the engine is just started cold, its temperature should be close to the temperature of the outside air. For instance, on some Volkswagen cars the code P0116 was commonly caused by a bad temperature sensor. This code could be caused by a bad or contaminated O2 sensor itself, sensor wiring problems or plenty of other reasons, such as exhaust leaks, too lean or too rich condition, intake leaks, a bad mass air flow sensor, etc. If you have codes for both banks (P0134 and P0154) stored at the same time, the problem is more likely not with the oxygen sensors, as both sensors would rarely fail at the same time. Read more about an oxygen sensor and what does it mean "Bank 1 Sensor 1" here: Oxygen sensor - illustrated glossary.
Normally the rear oxygen sensor's voltage changes slightly when the fully warmed-up engine is accelerated (rich mixture) or decelerated (lean mixture).
Again, it could be the oxygen sensor itself, the wiring problem, low battery, and many other things. This could be caused by a number of reasons, such as low fuel pressure, plugged fuel filter, worn fuel pump, vacuum leaks, exhaust leaks, etc. If the batteries in your Mercedes Benz SmartKey are depleted, you cannot use the SmartKey to get in the car or start it. Checking the power steering fluid level in your C300 is relatively easy and should be done once a month or if you are experienced difficulty turning the wheel or steering your C300.
To properly diagnose a check engine light problem, take your car to a local repair shop or a dealer, where a mechanic can do some tests with a scan tool and check a number of components to determine what exactly caused the problem. If the signal from the mass air flow sensor is out of expected range, the ECM detects a fault and sets the code P0100. The freeze frame is a snapshot of the engine parameters at the moment when the fault was detected. Nissan), when the new air flow sensor is installed, the fuel trim learned value must be reset.
It is installed between the air filter and the throttle valve, so that the intake air is passing through the sensor. The code P0102 is set when the signal from the mass air flow sensor is lower than expected.
In some Volkswagen cars, the code P0102 is often caused by a faulty mass airflow sensor; the repair often involves replacing the mass air flow sensor and clearing the code if no other problems found. The MAF readings at different RPMs need to be compared to the readings of a known good sensor. In some cars the ECM could use the signal from the MAP sensor to check the operation of the EGR system, as well as to check rationality of other sensors.
If you have a scan tool, select Data Monitor mode and check the MAP sensor reading with ignition ON, engine OFF. In Mazda, the EGR Boost Sensor is connected through the EGR boost sensor solenoid that also could be defective.


If the difference between the data from the engine coolant temperature sensor and the intake air temperature sensor is too great, the computer sets the code P0116. Checking the freeze frame data should help to diagnose the problem, as the freeze frame will show the engine temperature sensor reading as well as data from other sensors at the moment the fault was detected. An oxygen sensor can be checked with a lab scope or OBDII scan tool; take your car to your mechanic for proper diagnostic.
This may happens, for example, when the oxygen signal wire gets shorted to a power wire somewhere in the harness. Read more about an oxygen sensor and what means "Bank 1 Sensor 2" here: Oxygen sensor - illustrated glossary. If the voltage from the rear O2 sensor doesn't change as expected for a certain period of time, the code P0136 is set. If the new mass airflow sensor is installed, make sure the air filter is installed properly, as the sand particles coming with the unfiltered air can damage the airflow sensor. For example, a Toyota Technical Service Bulletin (TSB) for 2003-2008 Toyota Corolla and 2003-2008 Toyota Matrix lists a leaking intake manifold gasket as a possible reason for the code P0171 along with some other codes. For example, a Ford TSB for a number of late 90-s Ford vehicles describes a problem with MAF sensor contamination where both codes, P0171 and P0174 would appear together.
You can remove the mechanical key hidden in the widest end of the SmartKey and use that, but changing the batteries is a simple process that anyone can do.
For example, the mass air flow sensor signal could be higher than expected when the engine is not running or lower than expected with the engine running.
The air flow measurements are used by the engine computer (PCM) to adjust the amount of fuel injected by the fuel injection system and to calculate the engine load. Often a car may exhibit some driveability symptoms, such as lack of power, surging, hesitation on acceleration, hard starting, pinging (detonation), or rough idle when started cold. The MAP reading should be close to that of BARO sensor, as with the engine OFF, the pressure inside the intake manifold is equal to the atmospheric pressure. Take your car to a repair shop for proper diagnostic, your mechanic can scan the car computer and check the freeze frame. Sometimes, a car manufacturer may recommend an engine computer to be reprogrammed to address this problem. If the computer detects an open, short, or an excessive current draw in the heating element circuit of the front oxygen sensor of the bank 1 (Bank 1 Sensor 1), it sets the code P0135.
This could be caused by a faulty oxygen sensor itself, corrosion in the sensor connector, problem with the sensor wiring, exhaust leak or a number of other causes.
Check for vacuum leaks, there are not uncommon in F150: you may hear it as a hissing noise from under the hood. Some car manufacturers list the description for the code P0170 as self adaptation out of limits. A car with the code P0100 may have some driveability issues, such as stalling, lack of power, surging, hesitation, etc. Often the codes P0171 or P0174 could also be stored along with the code P0102, as the incorrect air flow signal can cause the engine to run lean.
Volkswagen, Audi) have a screen inside the air duct before the air filter that might be called Snow Screen. A vacuum leak is another possibility - see if the intake air duct is connected properly and the vacuum hoses are not ripped. In some cars, the code P0100 can cause the fail-safe mode where the engine speed would be limited to 2,500 - 3,000 rpm. It's always best to use the original part, as an incorrect MAF sensor also could cause problems.
This screen needs to be checked for blockage, as often leaves and other debris block the air flow. Also, on some cars, using aftermarket oxygen sensors instead of original is known to cause the fault code P0132. If you or your mechanic has a scan tool, check the Long Fuel Trim and Short Fuel Trim on Bank 1 and Bank 2.
The mass air flow sensor needs to be checked for contamination or dirt blocking the sensor element. Some car manufacturers may also recommend reprogramming of the engine computer (ECM) if the code P0132 is present.
If the mass air flow sensor element is dirty, cleaning it may help temporarily; however, the element is very delicate and should be cleaned very carefully to avoid damage. If the air-fuel mixture is normal at high rpms but leans out at idle, most likely you have a vacuum leak. The signal voltage or frequency needs to be checked at different engine RPMs and compared to the reference chart. The easiest way to check the mass air flow sensor is with a scan tool, reading the measured air flow at different RPMs.
Most of the time the solution for the code P0102 involves replacing the mass air flow sensor if no other problems found. An improper or poor quality part also can cause the code P0102, so it's better to use an OEM mass air flow sensor.
