Diagnostic Test
1. BOOST PRESSURE SENSOR CALIBRATIONTurn 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 hpa within 2% or the Atmospheric pressure hpa?
Yes
- Test Complete.
No
- Replace the Turbocharger Boost Pressure Sensor.
- Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)
