Electrical error on indoor temperature sensor. Sensor is missing/error.
â–¶ How to fix
* Check wiring (to indoor temperature sensor) * Check connectors (to indoor temperature sensor) * Check indoor temperature sensor * Measure the sensor voltage between signal (B8) and ground (B12)
What you'll see
No driver-visible symptom recorded.
System reaction
Functions dependent on the indoor temperature sensor might be degraded.
Diagnostic depth
Detection
Impressible signal from the indoor temperature sensor. The sensor is faulty or voltage level is too high.
Possible cause
*Defect wiring - open circuit on sensor ground (B12) - short circuit to supply voltage * Defect connectors * Defect sensor
