Hva betyr feilkoden?
This fault code concerns the reading of the intake air temperature sensor at the inlet, which is either too low or too high. It can come from a short to voltage, an open circuit or a damaged sensor, but also from poor contact.
Mulige årsaker
- Signal wire shorted to ground
- Contact resistance, oxidation or looseness in the connections
- Open circuit in the signal wire
- Signal wire shorted to voltage
- Damaged air temperature sensor at the inlet
Hva du kan gjøre
- 1With the ignition on, use a multimeter to check that the signal wire is not shorted to ground
- 2Look for loose connections and oxidation at the sensor
- 3If you have a diagnostic tool: read the sensor value in live data and check that it is reasonable for the intake air
- 4Have a workshop check the sensor if the wiring is in order
Symptomer du kan merke1
- Check engine lamp (MIL) lights up
