TROUBLESHOOTING USING GSC FAULT CODES - Continued
NOTE
The following codes are generated when the intake air manifold temperature sensor sees
a temperature greater than 194 F (90 C) for two seconds or longer (FMI 00); or greater than
228 F (109 C) (FMI 11) for two seconds or longer. This problem is often caused by one of the
following:
Incorrect fuel injection timing
Low air inlet system pressure
Restriction in air inlet
SYMPTOM
22.
CID 172 E FMI 00
CID 172 E FMI 03
CID 172 E FMI 04
CID 172 E FMI 11
MALFUNCTION
Intake manifold air temperature sensor.
FMI 00 - Data is Valid but Data is Above Normal Operating Range.
FMI 03 - Voltage above normal.
FMI 04 - Voltage below normal.
FMI 11 - Failure mode is not identifiable (Mechanical Failure)
CORRECTIVE ACTION
STEP 1.
Inspect and service air cleaner per TM 9-6115-730-10.
STEP 2.
If air cleaner required service, verify the fault code has cleared. If not continue to
the next step.
STEP 3.
On EMCP, turn ENGINE CONTROL switch to OFF/RESET. Battery Disconnect
switch is OFF, DEAD CRANK SWITCH is OFF.
STEP 4.
Inspect connectors ENG-P2 on the engine harness (FO-2, sheet 1) and ENG-P1
on the ECM to EMCP Harness (FO-2, sheet 2).
STEP 5.
Conduct an appropriate pull test on wires in the ENG-P2 and ENG-P1 connectors
to ensure wires are tight and secure.
STEP 6.
Check the wires on both harnesses for abrasion and pinch points (WP 0088).
Repair and/or replace the connectors and/or wiring (WP 0088).
