P0524- ENGINE OIL PRESSURE IS TOO LOW





For a complete wiring diagram Refer to Section 8W



Possible Causes
MECHANICAL PROBLEM
OIL PRESSURE SENSOR FAILURE
OIL PRESSURE SENSOR CIRCUIT(S) OPEN OR HIGH RESISTANCE
INTERMITTENT CONDITION



Diagnostic Test

1. CHECKING FOR CURRENT DTC

NOTE: Perform Pre-diagnostic test before continuing


NOTE: Ensure the engine oil level is at the specified level and the engine oil filter is the specified filter for this specific engine application.


NOTE: If there are Engine Oil Pressure Sensor circuit High/Low DTC's, repair the circuit High/Low DTC's before continuing with this test.


Turn the ignition on.
With the scan tool, erase ECM DTCs.
Start the engine several times, letting the engine run for at least 30 seconds at a time.
With the scan tool, read ECM DTCs.

Did this DTC set again?

Yes


No

2. MECHANICAL PROBLEM

Refer to the Service Information and perform the Engine Oil Pressure Test.

Is the oil pressure within specification?

Yes


No

3. CHECKING OP SENSOR CIRCUITS

Turn the ignition off.
Disconnect the Oil Pressure Sensor harness connector.
Disconnect the ECM harness connectors.
Measure the resistance of the each of the Oil Pressure Sensor circuits (3) between the Oil Pressure Sensor and the ECM harness connectors.

Is the resistance below 10.0 ohms for each of the measurements?

Yes


No
