Clio Intake Air Temperature Sensor Fault
Summary of the thread
A 2010 Renault Clio diesel is experiencing low power, rough running, and a check engine light, with an OBD reader indicating an intake air temperature sensor fault. The issue could be due to a faulty sensor or a problem with the wiring and connector. It is suggested to inspect the wiring and connector first, as a loose connection might cause the problem. If the wiring is intact, the sensor itself may need replacement, which resolved the issue in a similar case.

Good shout! I wiggled the connector, but didn't properly inspect the wiring. Was your problem definitely the sensor, or did you find something else? I'm trying to decide if I can fix it myself or take it to a garage.

Honestly, check the wiring properly if you haven't already. If the wiring is ok, it was unfortunately the sensor in my experience. I ended up just taking it to a workshop. Less stress!

Thanks for the advice! I'll trace the wiring and prepare for the worst. For anyone else with this issue: it ended up being the intake air temperature sensor. Workshop confirmed and replaced it. Cost 155€ including part and labour. Runs like a dream now. Thanks again!

Sounds familiar! I had almost the exact same symptoms on my Clio: gutless performance, rough idling. The temperature reading seemed off to me too. Have you checked the wiring and connector to the sensor itself? Sometimes a loose connection can cause havoc.
