Camshaft Position (CMP) Sensor, Checking

Camshaft Position (CMP) Sensor, Checking







Recommended special tools and equipment
- V.A.G 1526A multimeter
- V.A.G 1527 B Voltage Tester
- V.A.G 1594A connector test kit
- V.A.G 1598/31 test box







- 3094 hose clamps

Test requirement:
- Ignition switched off.

Checking activation
- Connect voltage tester e.g. V.A.G 1527 B with measuring probes and connector adapters from V.A.G 1594 A between terminal 2 (CMP sensor signal) and terminal 1 (B+); the harness connector remains connected.

NOTE: Connector sockets are numbered respectively on the rear side of the connector.

- Operate starter for a few seconds.
- LED must blink.

NOTE: Voltage testers do not go out completely during low current pick-up between activations by the ECM, but rather continue to glow a little and then get significantly brighter during activation.

- Switch ignition off.

If LED does not blink.
