Co oznacza ten kod błędu?
The code is set when the actual throttle position differs from the throttle angle the engine control module (ECM) requests. It can also be set when the inlet control valve has jammed in the open position while the control module is operating it.
Możliwe przyczyny
- The throttle is sticking or blocked, for example by dirt or ice
- Damaged electronic throttle unit
- The inlet control valve has jammed in the open position
- Damaged inlet control valve
Co możesz zrobić
- 1Clear the code and road test to see whether it returns
- 2If you have a diagnostic tool: read the actual throttle position and the reference value in live data at idle, and see whether they follow each other as the engine speed changes
- 3Check that nothing is blocking the throttle and that the throttle disc moves freely when pressed gently
- 4Clean the throttle unit carefully if there is dirt
- 5If you find no fault: have a workshop with diagnostic equipment check the throttle unit and the inlet control valve
