TROUBLESHOOTING USING GSC FAULT CODES - Continued
NOTE
The secondary engine timing sensor on this engine is the bottom crankshaft timing sensor.
SYMPTOM
42.
CID 342 E FMI 02
CID 342 E FMI 11
MALFUNCTION
Secondary (bottom) 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-P5 from the secondary (bottom)
engine timing sensor (WP 0090, 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.
STEP 3.
Measure engine timing sensor resistance.
a. If resistance is not 600 to 1800 ohms, replace engine timing sensor (WP
b. If resistance is correct, inspect and adjust engine timing (WP 0013,
SYMPTOM 11).
c.
SYMPTOM 4).
STEP 4.
Disconnect engine harness connector ENG-P2 from ECM J2 (WP 0090, Figure
2, Sheet 3, and FO-2, Sheet 1).
STEP 5.
Connect ENG-P5 to secondary (bottom) engine timing sensor.
STEP 6.
Inspect engine harness and measure continuity between ENG-P2-58 and ENG-
P2-59 (WP 0090, 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
0090), as necessary.
STEP 7.
Verify the problem has been resolved.
