Checking wire connections between Camshaft Position (CMP) sensor and Engine Control Module (ECM)
- Connect test box to wiring harness of Engine Control Module (ECM). See TEST BOX, CONNECTING FOR WIRING AND COMPONENT TEST . ECM is NOT connected.
- Check the following wire connections for open circuit according to wiring diagram:
- Camshaft Position (CMP) Sensor 2 -G40- (bank 1)CMP SENSOR CIRCUIT TEST: SENSOR 2 -G40- (BANK 1)
Harness connector Terminal Test box Socket 1 (B+) 98 2 (signal) 87 3 (Ground -GND-) 108 - Camshaft Position (CMP) Sensor 2 -G163- (bank 2)CMP SENSOR CIRCUIT TEST: SENSOR 2 -G163- (BANK 2)
Harness connector Terminal Test box Socket 1 (B+) 98 2 (signal) 86 3 (Ground -GND-) 108 - Camshaft Position (CMP) Sensor 2 -G300- (bank 1)CMP SENSOR CIRCUIT TEST: SENSOR 2 -G300- (BANK 1)
Harness connector Terminal Test box Socket 1 (B+) 98 2 (signal) 81 3 (Ground -GND-) 108 - Camshaft Position (CMP) Sensor 2 -G301- (bank 2)CMP SENSOR CIRCUIT TEST: SENSOR 2 -G301- (BANK 2)
Harness connector Terminal Test box Socket 1 (B+) 98 2 (signal) 54 3 (Ground -GND-) 108 - Specified value: Wire resistance max 1.5 Ω
- Camshaft Position (CMP) Sensor 2 -G40- (bank 1)
- Also check wires for short circuit to each other as well as to B+ and Ground (GND).
- Specified value: INFINITY Ω (no continuity)
- If necessary, repair wire connection.
