Was bedeutet der Fehlercode?
The engine control module counts the teeth on the flywheel through the signal from the engine speed sensor. If it counts at least one tooth too few within a set number of engine revolutions, the code is set. The cause may be interference, an incorrectly fitted sensor or a damaged flywheel or ring gear.
Mögliche Ursachen
- Signal interference from nearby cables
- Incorrectly fitted engine speed sensor
- Damaged flywheel or ring gear
Was Sie tun können
- 1Check that the connector to the engine speed sensor is firmly seated and free from oxidation
- 2Check whether the starter motor cable or other high-current cables run too close to the sensor wiring, and that they are routed correctly
- 3Check that the engine speed sensor is correctly fitted
- 4Have a workshop check that the engine-to-transmission bolts are correctly tightened, since poor earthing can disturb the sensor
- 5If the fault remains, have a workshop examine the flywheel and ring gear
Symptome, die Sie bemerken können2
- Engine is difficult to start
- Poor performance
Was der Fehler beeinflussen kann2
- If the camshaft position sensor is adapted, the control module takes its signal instead
- VVT control is blocked
