CID 94 FMI 01
CID 94 FMI 02
Fuel pressure sensor.
FMI 01 - Data is Valid but Data is Below Normal Operating Range.
FMI 02 - Erratic, Intermittent, or Incorrect Signal.
Set Battery Disconnect Switch to ON. Set DEAD CRANK SWITCH to NORMAL.
On EMCP turn the ENGINE CONTROL switch to COOL DOWN/STOP.
Disconnect engine harness connector ENG-P17 from fuel pressure sensor (WP
1 and FO-2, sheet 1).
Measure voltage between ENG-P17-A (+) and ENG-P17-B (-) of harness
a. If voltage is not present, repair or replace harness (WP 0090). Verify the
problem has been resolved.
b. If repairing wiring does not resolve fault, replace the fuel pressure sensor
If voltage is not present between ENG-P17-A (+) and ENG-P17-B (-) proceed
to STEP 3d.
d. Remove ENG-P2 from ECM and verify continuity between ENG-P17-C and
ENG-P2-16 per FO-2, sheet 1.
(1) If continuity is not present, repair or replace harness (WP 0090). Verify
the problem has been resolved.
(2) If the problem is not resolved, replace ECM (WP 0084).
Verify the problem is resolved.
