The accelerator pedal (Throttle Position Sensor) is an electrical item that is connected to the engine ECU and has been know to give problems with poor acceleration or lack of power at times on a diesel C3.
Here are some pictures of the 3 bolts and the electrical connection and some photos of the TPS removed from the car for cleaning.corkish wrote: Decided to work through the various systems and eventually came back to the throttle pedal. As this engine is fly by wire I thought this was worth checking so I removed this pedal assembly, 3 x 10mm bolts and one electrical connector, five mins work.
As I did not have a spare to hand I disassembled what I could carefully without breaking it!
Then proceeded to clean the entire electrical assembly of the pedal with a good quality electrical component cleaner.
The difference is very noticeable, no lag or hesitation and much smoother throughout the rev range.

I couldn't get much disassembly of the sensor on this Bosch TPS, it is possible to remove the 2 semicircular side pieces, but you don't get to view much more with these removed. Cleaning the whole head with some quality contact cleaner (ebay) was all I could achieve.
Tap the centre pins through the back of the unit to release the clips. You can then remove the 2 semicircular covers.
