Juke Hybrid Air Quality Sensor Failure

My 2023 Nissan Juke Hybrid's air quality sensor seems to have failed; the blower motor isn't working. I've checked the wiring and connectors and can't see any damage. The car has 221128 km on it. I think it might be a cable or plug issue. Has anyone else had a similar AUC sensor problem?

The 2023 Nissan Juke Hybrid experienced an air quality sensor failure, leading to a non-functional blower motor. Despite checking wiring and connectors with no visible damage, the issue persisted. A diagnostic scan confirmed the AUC sensor as the problem, even without shorts or open circuits. Replacing the sensor resolved the issue, restoring the blower motor's functionality.

Did this summary help you solve your problem?

I understand. A faulty connection sounds right, given what you've checked. Have you done a diagnostic scan to confirm it's the AUC sensor? A regular OBDII scanner might not be detailed enough. Also, check the blower motor fuse, though that wouldn't explain the sensor issue.

I scanned it with a professional tool, and it flagged the AUC sensor specifically, but no shorts or open circuits. I checked the fuses too, and they're fine. Could a bad sensor stop the blower, even without a detected short?

Yes, a faulty AUC sensor could stop the blower, even without a short. The sensor tells the climate control system what to do, and a bad reading could disable the blower as a safety measure. Since you've checked the wiring and fuses, the sensor probably needs to be replaced. I'd suggest a workshop for diagnosis and repair.

Thanks for the advice. I replaced the AUC sensor at a local shop. The total cost was 95€. The blower motor is working now.
