Hi there, Been trying to fix my brothers Clio 1.2 16v for the past few days - he left to work in Canada and now I've to sort it!
Basically when you turn the key it revs to 3500rpm on its own.
My cheap code reader brings up P0638 - P0638 Throttle Actuator Control Range/Performance
So far I have:
- Checked the original throttle body/cleaned it out.
- Checked and cleaned the accelerator pedal plug and TB plug.
- Changed the accelerator pedal with a replacement part.
- Changed the TB with a replacement part.
- Checked all fuses/relays etc - taken apart, sanded the pins/contact cleaner everywhere.
- Checked the wiring looms for any breaks.
- Checked for any leaks around the TB, inlet manifold, checked for loose or split hoses.
- Checked all plugs around the engine/cleaned.
- Replaced the MAP sensor.
- Removed and cleaned coilpacks and sparks.
- Removed battery and checked all terminals are tight.
Things possibly:
- O2 Sensor/ECU.
- Proper tools to realign the TB?
Does any have any further ideas/access to Renault CLIP diagnostics?
