Integra AUC Sensor Fault

Greetings. An AUC sensor fault manifesting as blower motor failure in a relatively new vehicle is certainly... unexpected. Before we jump to conclusions regarding the sensor itself, may I inquire whether you have performed any preliminary diagnostics? Specifically, have you verified the integrity of the blower motor fuse and relay? Furthermore, has the system been subjected to a diagnostic scan to ascertain the precise error code(s) being generated? It would be most helpful to understand the diagnostic process you have undertaken thus far.

Yes, I checked the fuses and relays, all good. It's throwing a specific AUC sensor fault code. The diagnostics point to a defective cable or plug connection.

Acknowledged. Given the confirmation of a specific AUC sensor fault code and the identification of a potentially defective cable or plug connection, I must concede the plausibility of your initial assessment. Regrettably, troubleshooting electrical faults within modern automotive systems can prove exceedingly complex, even with advanced diagnostic tools. In light of this, and considering the relative youth of your vehicle, I would strongly recommend consulting with a qualified automotive technician at your earliest convenience.

Thanks for confirming my suspicion. I took it to the shop, and you were right, it was a bad connector on the AUC sensor. 95€ later, it's fixed.
