Checking wire connections between Camshaft Position (CMP) sensor and Engine Control Module (ECM): Notes
- Connect VAG1598/31 test box at wiring harness to ECM; do not connect ECM. See WIRE AND COMPONENT TEST USING VAG1598/31 TEST BOX .
- Check following wire connections for open circuit and short circuit to Ground (GND) and B+:
Camshaft Position (CMP) Sensor -G40- (Bank 1)
CMP SENSOR -G40- (BANK 1) CIRCUIT TEST: TERMINALS 1, 2, 3
| Harness connector Terminal | VAG1598/31 test box Socket |
|---|---|
| 1 (B+) | 98 |
| 2 (signal) | 86 |
| 3 (Ground -GND-) | 108 |
Camshaft Position (CMP) Sensor 2 -G163- (Bank 2)
CMP SENSOR -G163- (BANK 2) CIRCUIT TEST: TERMINALS 1, 2, 3
| Harness connector Terminal | VAG1598/31 test box Socket |
|---|---|
| 1 (B+) | 98 |
| 2 (signal) | 87 |
| 3 (Ground -GND-) | 108 |
- Repair open circuit or short circuit if necessary.
- If, after erasing DTC memory, a DTC relating to Camshaft Position (CMP) sensor (hall sensor) is indicated again, even though all previous tests were OK, following malfunction is possible:
