CID 0460 FMI 04 Filtered Fuel Pressure short to ground
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the following condition:
- Voltage for the fuel pressure sensor is below 0.2 VDC (short to ground) for one second.
- The ECM has been powered for at least three seconds.
- 262-03 or 263-04 are not active.
System Response:
The ECM flags the fuel pressure as invalid data. The ECM will log the diagnostic code. The diagnostic code may be viewed on a display module or on the Caterpillar Electronic Technician (ET).
Test Step 1. Perform the following diagnostic procedure: "Analog Sensor Supply Circuit - Test"
Results:
- OK - STOP
