Hva betyr feilkoden?
The engine control module (ECM) monitors the engine speed (RPM) signal from its sensor, which reports how fast the crankshaft is turning. If the sensor gives a signal that does not look right, the code is set. Engine torque may be limited, and the car may feel weaker than usual.
Mulige årsaker
- Contact resistance at the sensor terminals
- Open circuit in the wiring to the engine speed sensor
- Damaged or dirty engine speed sensor
- Internal fault in the engine control module
Hva du kan gjøre
- 1Check that the engine speed sensor is correctly installed and not damaged
- 2Check that the sensor connector is fully engaged and free from oxidation
- 3Check that the sensor is clean, since dirt can affect the signal
- 4If you have a diagnostic tool, check the engine speed in live data with the engine running; the reading should be steady at idle and change smoothly when the engine is revved
- 5With the ignition off, use a multimeter to check that the signal wire to the sensor has no open circuit and is not shorted to earth or to supply voltage
- 6If the fault remains after these checks, the engine control module may be faulty; a workshop should decide whether it needs replacing
Symptomer du kan merke2
- The car lacks power or performs poorly
- Yellow warning symbol and text message in the display
Hva feilen kan påvirke1
- Engine torque is limited
