CID 1835 FMI 04 Auxiliary Pressure Sensor short to ground
Conditions Which Generate This Code:
The signal voltage from the auxiliary pressure sensor is less than 0.2 VDC for one second.
System Response:
The Electronic Control Module (ECM) logs the diagnostic code. The value of the auxiliary pressure defaults to 45 kPa (6.5 psi).
None
Test Step 1. Perform the following diagnostic procedure: Engine Sensor Open/Short Circuit - Test
Results:
- OK - STOP
