Co oznacza ten kod błędu?
The engine control module (ECM) compares the actual position of the intake air control valve with a calculated reference value. If the two do not match, the fault code is stored. The fault code means the valve is mechanically stuck in the open position.
Możliwe przyczyny
- The control valve is stuck in the open position
- Damaged control valve in the intake air inlet
Co możesz zrobić
- 1Read the fault code, clear it and test drive the car with the engine running to see whether it returns
- 2Check that the flap in the intake pipe moves freely and is not stuck open; remove dirt or debris that blocks its movement
- 3Check that the fuses are intact; their locations are shown in the owner's manual or on the fuse box cover
- 4If you have a diagnostic tool: compare the valve's reference value and actual position in live data with the engine running, and see whether the actual position follows the reference
- 5If the fault returns: have a workshop with diagnostic equipment check the control valve and replace it if it is damaged
