Gilt für folgende Modelle:

Was bedeutet der Fehlercode?
The engine control module receives too low a signal from the air temperature sensor. The air temperature sensor measures the temperature of the intake air, and the engine control module uses the value to control fuel injection. The fault is recorded as intermittent, meaning it comes and goes, and may not be visible right now.
Mögliche Ursachen
- The signal wire is shorted to earth
- Contact resistance in the connections
- Break in the signal or earth wire
- Faulty air temperature sensor
Was Sie tun können
- 1Check the wires and connectors to the air temperature sensor for chafing, play and corrosion
- 2Because the fault is intermittent, note whether the engine is only hard to start when cold, or also when warm
- 3Measure with a multimeter that the signal and earth wires to the sensor have no break, and that the signal wire is not shorted to earth
- 4Clear the fault code and road test the car to see whether it returns
- 5If it returns, have a workshop with diagnostic equipment investigate the air temperature sensor and the engine control module
Symptome, die Sie bemerken können1
