Was bedeutet der Fehlercode?
The engine control module (ECM) monitors the idle speed control and sets the code when the idle speed is lower than expected. The causes may be a clogged fuel filter or low fuel pressure.
Mögliche Ursachen
- Clogged fuel filter
- Low fuel pressure
Was Sie tun können
- 1Check that the fuses are intact. Their location is in the owner's manual or on the fuse box cover.
- 2Check when the fuel filter was last changed. A clogged filter can give low fuel pressure and low idle, and it should be changed on schedule if it is old.
- 3With the ignition on, listen for the fuel pump starting for a few seconds.
- 4If you have a diagnostic tool, read the idle speed in live data with the engine warm, and check whether it drops lower than expected.
- 5If the fault remains, have a workshop measure the fuel pressure and check the fuel system.
Symptome, die Sie bemerken können1
- Idle is too low or unstable, and it may be noticeable all the time or only now and then
