TPS/Throttle Body Making Noise (P2174)
2005 Cayenne V6:
The throttle body makes noise at idle (more evident on cold start). Its sort of a fluttering/grinding noise. I imagine that the throttle plate is being quickly opened/closed.
So I am not sure if this would be the throttle body assembly itself or if this is just a symptom of something like a vacuum leak and the TPS is trying to compensate for it?
Durametric gives P2174: Throttle/Pedal Position Sensor/Switch E Circuit: Implausible signal, testing conditions are not completed, fault is not currently active and is not causing a DTC light.
