TROUBLESHOOTING USING GSC FAULT CODES - Continued
NOTE
The camshaft (top) engine timing sensor functions as the backup timing sensor in the event the
crankshaft (bottom) engine timing sensor fails.
SYMPTOM
39.
CID 342 E FMI 02
CID 342 E FMI 11
MALFUNCTION
Camshaft (Top) Engine Timing Sensor.
FMI 02 - Erratic, Intermittent, or Incorrect Signal.
FMI 11 - Failure mode is not identifiable (Mechanical Failure).
CORRECTIVE ACTION
STEP 1.
Turn the ENGINE CONTROL switch to OFF/RESET. Battery Disconnect switch
is OFF, DEAD CRANK SWITCH is OFF.
STEP 2.
Disconnect engine harness connector ENG-P402 from the camshaft (top) engine
timing sensor (WP 0088, Figure 2, sheet 1, and FO-2, sheet 1). The sensor
connector has a wire clip that must be removed in order to disconnect the
connector from the sensor.
a. Measure engine timing sensor resistance.
b. If resistance is not 600 to 1800 ohms, replace camshaft (top) engine timing
sensor (WP 0098).
c.
If resistance is correct, inspect and adjust engine timing (WP 0013,
SYMPTOM 3.
SYMPTOM 3).
STEP 3.
Disconnect engine harness connector ENG-P2 from ECM J2 (WP 0088, Figure 2,
Sheet 3, and FO-2, Sheet 1). Connect ENG-P402 to the camshaft (top) engine
timing sensor (WP 0088, Figure 2, sheet 1, and FO-2, sheet 1)
STEP 4.
Inspect engine harness and measure continuity between ENG-P2-58 and ENG-
P2-59 (WP 0088, Figure 2, sheet 3). Measurement should be approximately the
same as in STEP 2 b. If open or shorted, repair or replace engine harness
(WP 0088), as necessary.
STEP 5.
Verify the problem has been resolved.
