Was bedeutet der Fehlercode?
During the same operating cycle the engine control module has repeatedly lost the signal from the intake air temperature sensor, more often than allowed. The fault is intermittent, meaning the signal has dropped out and then returned. It is checked while driving and usually goes unnoticed by the driver.
Mögliche Ursachen
- Open circuit or short circuit to ground in the signal wire
- Short circuit to supply voltage in the signal wire
- Damaged intake air temperature sensor
Was Sie tun können
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the intake air temperature sensor connector is secure and free from oxidation and contact resistance
- 3Use a multimeter to check the signal wire for an open circuit and a short circuit to ground
- 4Use a multimeter to check the signal wire for a short circuit to supply voltage
- 5If the fault remains with a clean connector and an intact wire, have a workshop check the sensor
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
