Was bedeutet der Fehlercode?
The code concerns a signal that is too low from some of the engine's sensors, where the supply from the ECM is the part being monitored. It is set when the supply voltage is too low or too high. Tracing is done through the other fuel system codes.
Mögliche Ursachen
- Supply cable to the sensors shorted to battery voltage
- Fault in the fuel system, to be traced through the other fuel system codes
Was Sie tun können
- 1Check that the relevant fuses are intact and that the battery is in good condition
- 2Where possible, check the relevant functions of the car with the buttons, controls or a test drive
- 3With the ignition off, use a multimeter to check that the supply wire to the sensors is not shorted to battery voltage
- 4Trace the other fuel system fault codes first
Symptome, die Sie bemerken können3
- The car performs poorly and lacks power, especially at take-off
- The engine hesitates or surges during acceleration, during deceleration or at steady speed
- Warning symbol and text message in the display
