    Camshaft Position Sensor, Checking
    NoteUse only gold-plated terminals when servicing terminals in harness connector of Camshaft Position (CMP) Sensor -G40-.
    Special tools and workshop equipment required
    t Multimeter.
    t Wiring diagram.
    Test requirements
    l The Motronic Engine Control Module (ECM) - J220- fuses OK.
    l All electrical consumers such as, lights and rear window defroster, switched off.
    l Vehicles with automatic transmission, shift selector lever into position “P” or “N”.
    l A/C switched off.
    l Ground (GND) connections between engine/transmission/chassis OK.
    l Ignition switched off.
    Test procedure
    – Perform a preliminary check to verify the customers complaint. Refer to → Chapter.
    Start diagnosis
    – Remove the engine cover with air filter.

    – Disconnect the Camshaft Position (CMP) Sensor -G40- electrical harness connector -arrow-.
    – Switch the ignition on.

    – Using a Multimeter, Check the Camshaft Position (CMP) Sensor -G40- 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 Adapter Cable (121-pin) -VAG1598/31-

    → Engine Mechanical, Fuel Injection and Ignition; Rep. Gr.24; Removal and Installation.
    If the manufacturers test box is not being used. Perform the following step.
    – Remove the Motronic Engine Control Module (ECM) -J220-. Refer to → Chapter.

    – Using a Multimeter, Check the Camshaft Position (CMP) Sensor -G40- electrical harness connector to the Motronic Engine Control Module (ECM) -J220- electrical harness connector T121 for resistance.

    Camshaft Position (CMP) Sensor -G40- electrical harness connector terminals Motronic Engine Control Module (ECM) -J220- electrical harness connector T121 terminals or test box sockets

    2 86
    3 108

    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, loose 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 -G40-.
    – Erase the DTC memory. Refer to → Chapter.
    – Perform a road test to verify repair.
    If the DTC does not return:
    Repair complete, Generate readiness code. Refer to → Chapter.
    – End of diagnosis.
    If the DTC does return and no malfunction is detected in the wiring and the voltage supply was not OK:
    – Replace the Motronic Engine Control Module (ECM) -J220-. Refer to → Chapter.
    – Assembly is performed in the reverse of the removal.
    Final procedures
    After the repair work, the following work steps must be performed in the following sequence:
    1 - Check the DTC memory → Chapter.
