Evaporator temperature sensor
Use SDP3 to check the value from the evaporator temperature sensor.If the value is not correct, check the wiring and connector for the evaporator temperature sensor.If necessary, renew the evaporator temperature sensor.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 evaporator temperature sensor value is outside its limits.
The evaporator 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 evaporator temperature sensor.Defective evaporator temperature sensor.Evaporator temperature sensor loose.
