Camshaft Position (CMP) Sensor, Checking

Special tools and equipment
- VAG 1598/31 adapter cable
- VAG 1526 multimeter or VAG 1715 multimeter
- VAG 1594 connector test kit
- Wiring diagram

Test requirement
- Battery voltage must be at least 11.5 volts.

Test sequence







- Disconnect 3-pin connector -1- from Camshaft Position (CMP) sensor -2-.
- Use adapter cables from VAG 1594 to connect multimeter to outer terminals of connector for voltage measurement.
- Switch ignition on. Specification: at least 4.5 V
- Switch ignition off.







- Connect VAG 1598/31 adapter cable to control module wiring harness. Engine Control Module (ECM) is not connected.







- Check for open circuits in wires between test box and connector according to wiring diagram. Terminal 1 + socket 98, terminal 2 + socket 86, terminal 3 + socket 108, wire resistance: max: 1.5 Ohms
- Check wires for shorts among one another.

If no malfunctions are found in the wires and there was voltage between terminals 1 + 3:
- Replace Camshaft Position (CMP) Sensor 2 -G163-.

If no errors are found in wires and there was no voltage between terminals 1 + 3:
- Replace Engine Control Module (ECM).
