Hva betyr feilkoden?
The engine control module (ECM) follows the internal supply circuits to the sensors and sets the code when the voltage in one circuit is too low. The check runs with the ignition on. If another code for a sensor on the same supply is stored, it should be traced first, since it may be the cause.
Mulige årsaker
- The supply wire to the sensor is shorted to ground
- The sensor is damaged
- The control module is damaged
Hva du kan gjøre
- 1Trace first any codes for sensors fed from the same supply, since they may be the cause
- 2Read the code, clear it and road test the car to see whether it comes back
- 3Use a multimeter to check that the supply wire to the sensors has no contact with ground (the body)
- 4Check the sensor connectors for oxidation and loose fit
- 5If the code remains after these checks, have a workshop decide whether the control module needs replacing
Symptomer du kan merke2
- The starter motor does not turn
- The engine is hard to start
