Malfunction

PID170

Cabin air temperature sensor.

The climate control unit registers the voltage in the temperature sensor circuit above 4.86 V. The sensor is not connected to the control unit. It is possible that the signal or ground wire is shorted to a higher voltage.
The climate control unit registers the voltage in the temperature sensor circuit below 0.7 V. The signal wire is shorted to ground or the sensor is faulty.

PID171

Sensor temperature outdoor air .

The climate control unit registers the voltage in the temperature sensor circuit above 4.9 V. Shorting the signal or ground wire to a higher voltage. Probably defective sensor.
The climate control unit registers the voltage in the temperature sensor circuit below 0.55 V. The signal wire is shorted to ground or the sensor is faulty.
