Air temperature sensor
Use SDP3 to check the value from the air temperature sensor.Check the wiring and the air temperature sensor connector.Renew air temperature sensor if necessary.Clear the fault codes in the ACC control unit.
What you'll see
No driver-visible symptom recorded.
System reaction
No system-reaction text recorded.
Diagnostic depth
The air temperature sensor value is outside its limits.
The air temperature sensor has been exposed to undesirable positive voltages or is short circuited due to undesirable earthing, or the circuit is broken. If there is a short circuit to positive, the voltage is above 4.9 V. If there is a short circuit to metal, the voltage is above 0.1 V.If there is an open circuit, the voltage is above 4.9 V.Fault in the wiring or connector for the air temperature sensor.The air temperature sensor is defective.Air temperature sensor loose.
