Can the ECT sensor cause my AC Compressor/Clutch to not engage?
- The OBDII Scanner is reading PO118 01/01 (ECT sensor)
- The AC is blowing but not cold
- The AC Compressor Clutch is not engaging
No that is for engine management systems only. If the A/C is not operating then the most likely cause is low 134A. Look at the A/C systems lines and connectors, your looking for an oily film that might indicate a leak.
