    Angry Timing or cam sensor please help

    Hi to all. I've got a s3 2000 apy and has bad judder/ misfire. Scanned with vag-com and got code 17745/p1337. I've changed the cam sensor and check power to the connector reading 5v I have not checked the switch wire. The cambelt was change about 3 weeks ago could it be the timing out????

    17745/P1337/004919 - Camshaft Position Sensor (G40)
    17745/P1337/004919 - Camshaft Position Sensor (G40): Short to Ground
    Possible Symptoms

    Malfunction Indicator Lamp (MIL) active

    Possible Causes

    Camshaft Position Sensor (G40) faulty
    Wiring/Connectors from/to Camshaft Position Sensor (G40) faulty

    Possible Solutions

    Check Camshaft Adjustment
    Check Camshaft Position Sensor (G40)
    Check Wiring/Connectors from/to Camshaft Position Sensor (G40)

    Double check the wiring... its shared wiring on these... if you unplug the sensor, turn on ignition, clear codes and turn the engine over do you get an open circuit fault code instead? if you do then I suspect its a wiring fault in the loom somewhere... no other fault codes?

    Had this with hollies car, it was a timing error. It couldn't see the cam where it expected so it threw the fault. No idea why it didnt throw the correlation code, have to assume it was related to VVT. I think it was cam to cam over crank to cam. But given they have recently changed the cam belt, my bet it the error is there.
