WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Volkswagen Jetta, 2002 Volkswagen GTI, 2001 Volkswagen Jetta, 2001 Volkswagen GTI, and 2000 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect 3-pin harness connector from Camshaft Position (CMP) sensor G40 - arrow -.
- Connect multimeter to measure voltage with adapter cables from VW 1594 to terminals 1 (B+) and 3 (GND) on Camshaft Position (CMP) sensor G40 harness connector.
- Switch ignition on. Specified value: min. 4.5 V
- Switch ignition off.
If no voltage is present:
- Remove wiper arms and plenum chamber cover. → 92 WINDSHIELD WIPER & WASHER SYSTEM
- Connect Test box VAG 1598/31 to control module wiring harness. Engine Control Module (ECM) is not connected by this action.
- Check wiring for open circuit between test box and harness connector using wiring diagram. Terminal - 1 - + socket 98. Terminal - 2 - + socket 86. Terminal - 3 - + socket 108. Wire resistance: max. 1.5 Ω
- Also, check if wires are shorted together. Specified value: ∞ Ω
If no malfunction is found in the wiring and voltage was present between terminals - 1 - + - 3 - :
- Replace Camshaft Position (CMP) sensor G40.
- Check DTC memory. If necessary, repair any malfunctions and erase DTC memory → Diagnostic Trouble Code (DTC) memory, checking and erasing (scan tool functions 02 and 05) .
- Display readiness code → Readiness code (function 15), displaying . If the DTC memory has been erased, the readiness code must be generated again → Readiness code (function 15), generating .
If no malfunction is found in the wiring and no voltage was present between terminals - 1 - + - 3 - :
- Replace Engine Control Module (ECM) → Engine Control Module (ECM), replacing .
