CID 0164 FMI 04 Injector Actuation Pressure voltage low
Conditions Which Generate This Code:
The signal from the injection actuation pressure sensor is below normal.
System Response:
The ECM will log the diagnostic code. The ECM will flag injection actuation pressure as invalid data and a default value will be used. The ECM will set the current for the control valve to a fixed value.
- Low power
- Poor idle quality
Test Step 1. Perform the following diagnostic procedure: Analog Sensor Open or Short Circuit - Test
Results:
- OK - STOP
