TROUBLESHOOTING USING GSC FAULT CODES - Continued
CORRECTIVE ACTION - Continued
Conduct an appropriate pull test on wires in the ENG-P2 and ENG-P1
connectors to ensure wires are tight and secure.
Check the wires on both harnesses for abrasion and pinch points (WP 0090).
If necessary, repair and/or replace the connectors and/or wiring (WP 0090).
Disconnect the harness connectors, for the fuel pressure sensor, engine oil
pressure sensor, injection actuation sensor, turbo outlet pressure sensor,
atmospheric pressure sensor, and turbo inlet pressure sensor.
On EMCP, turn ENGINE CONTROL switch to COOL DOWN/STOP. Battery
Disconnect Switch is ON. DEAD CRANK SWITCH is set to NORMAL.
Measure 5.0 +/- 0.2 Vdc between terminals A (supply) and B (return) at each
If 5.0 +/- 0.2 Vdc is not measured on all sensor connectors, repair/replace ECM
If the problem is not resolved, perform the Injection Actuation Pressure Test (WP
0013, SYMPTOM 5). Perform sections
of the test that match the failure codes.
If the problem is not resolved, replace ECM (WP 0084).
Verify the diagnostic code has been cleared.
The ECM detected one of the following conditions:
Injection actuation pressure with the engine shut down
Substantial difference between actual and desired pressure
Change in injection actuation pressure was not consistent with change in sensor current
CID 164 E FMI 03
CID 164 E FMI 04
Injection actuation pressure system.
FMI 03 - Voltage Above Normal.
FMI 04 - Voltage Below Normal.
Troubleshoot injector actuation pressure sensor using steps in SYMPTOM 13.
