Camshaft Position Sensor 2

WARNING: This page is about a different car, the 2009 Audi S8, 2008 Audi S8, and 2007 Audi S8. However, it is still accessible from the selected car via links, so may be relevant.

The following procedure is used to diagnose Camshaft Position (CMP) Sensor 2 G163 which is controlled by Engine Control Module (ECM) 2 J624.

NOTE:

Use only gold-plated when servicing the electrical harness connector terminals of the Camshaft Position (CMP) Sensor 2 G163.

Special tools, testers and auxiliary items required

Multimeter.
Wiring diagram.

Test requirements

The Engine Control Module (ECM) 2 J624 fuses OK.
Battery voltage at least 12.5 volts.
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.

Using a Multimeter, Check the Camshaft Position (CMP) Sensor 2 G163 electrical harness connector terminals 1 to 3 for voltage.

Specified value: about 5.0 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. Refer to → .

If the manufacturers test box is not being used. Perform the following step.

Remove the Engine Control Module (ECM) 2 J624. Refer to → .

Specified value: 1.5 Ω Max.

If the specified value was not obtained:

Check the wiring connection for an open circuit, short circuit to Battery (+) or Ground (GND).
Check the wiring connection for damage, corrosion, lose or broken terminals.
If necessary, repair the faulty wiring connection.

If no malfunction is found in the wiring and voltage supply was OK:

Replace the Camshaft Position (CMP) Sensor 2 G163. Refer to → .

If no malfunction is found in the wiring and voltage supply was not OK:

Replace the Engine Control Module (ECM) 2 J624. Refer to → .
Assembly is performed in the reverse order of removal.

Final procedures

After repair work, the following work steps must be performed in the following sequence:

Check the DTC memory.
If necessary, erase the DTC memory. Refer to Diagnostic Mode 04 - Erase DTC Memory .
If the DTC memory was erased, generate readiness code. Refer to Readiness Code .

End of diagnosis.
