C8 2.0 HDi Throttle Position Sensor fault

[MikeRatcliffe]

My auto gearbox has been slipping a bit between 1st and 2nd gear so I took my car to a Citroen garage who tried and failed to read any diagnostics from the Transmission Control Unit... ECU version not supported error

They claimed that "the slipping is nothing to worry about and that it will be fine" so, knowing they are wrong, I took the car to a transmission specialist who through their diagnostics got a Throttle Control Sensor fault, which fits my symptoms.

Anyhow, I have cleaned plenty of throttle bodies on petrol cars to fix this particular fault but I don't see anything that I would expect to look like a throttle body in my engine.

So does anybody know where the throttle body and Throttle Control Sensor are in a C8 2.0 HDi? I just want to test the sensor and clean the throttle body.

The throttle position sensor is connected to the accelerator pedal.

The throttle position sensor on a c8 is fastened to the wiper mechanism under the scuttle panel. A diesel does not have a throttle flap, and the faulty device is just a potentiometer that relays information from the cable inputs to the engine ECU .You would just replace it with another unit, but I doubt it will cause your clutch slipping issue.
