*CHECKING THE BOOST PRESSURE SENSOR CALIBRATION

For a complete wiring diagram Refer to Section 8W

TURBOCHARGER BOOST PRESSURE SENSOR CALIBRATION

Diagnostic Test

1. BOOST PRESSURE SENSOR CALIBRATION

Turn the ignition on.
With the scan tool, read the Boost Pressure Voltage and Boost Pressure hpa.

NOTE: The Boost Pressure hpa and Intake/Inlet Air Pressure hpa readings should both match closely to the Atmoshperic Pressure hpa reading. These readings will change depending on altitude.

Is the Boost Pressure Voltage between 1.12 and 1.36 volt?

Yes

Test Complete.

Replace the Turbocharger Boost Pressure Sensor.

Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
