Hello,

Here is a guide to help you check the wiring and power to the sensors.

https://www.2carpros.com/articles/how-to-check-wiring

Here is the wiring diagrams (AT BOTTOM)

Some stuff from the manual:

The Engine Control Module (ECM) J623 fuses OK.
Engine Control Module (ECM) Power Supply Relay J363 OK.
Battery voltage at least 12.5 V.
All electrical consumers such as, lights and rear window defroster, switched off.
Vehicles with automatic transmission, shift selector lever into position "P" or "N".
A/C switched off. Ground (GND) connections between engine/transmission/chassis OK. Ignition switched off. Test procedure

Using a Multimeter, check the Camshaft Position (CMP) Sensor electrical harness connector terminal 1 to engine ground for voltage.
Camshaft Position (CMP) Sensor Electrical Harness Connector TerminalMeasure to 1
Engine Ground (GND)
Specified value: about 5 V. Switch the ignition off.

Checking signal wire
Using a Multimeter, Check the Camshaft Position (CMP) Sensor electrical harness connector terminal 2 to engine ground for voltage.
Camshaft Position (CMP) Sensor Electrical Harness Connector TerminalMeasure to 2
Engine Ground (GND)
Switch the ignition on.
Specified value: Battery voltage. Switch the ignition off.

Checking Ground (GND)
Using a Multimeter, Check the Camshaft Position (CMP) Sensor electrical harness connector terminal 3 to engine ground for voltage.
Camshaft Position (CMP) Sensor Electrical Harness Connector TerminalMeasure to 3
Battery positive (+)
Specified value: about 10 V.
Switch the ignition off.

If the specification was not obtained: Checking wiring
If the manufacturers test box is being used, perform the following step. Install the test box VAG1598/42. Refer to 24 - FUEL INJECTION SYSTEM.
If the manufacturers test box is not being used, perform the following step.

Please run some tests and get back to us so we can continue helping you.

Cheers, Ken
