Renault Spider IAT Sensor Issue

The symptoms you describe certainly point towards a potential issue with the intake air temperature (IAT) sensor. To be certain, could you share the exact error code you retrieved from the diagnostic tool? Knowing the specific code will help narrow down the possibilities. Also, have you observed any changes in fuel consumption recently?

Thanks for the quick response! The error code is P0113 - Intake Air Temperature Sensor 1 Circuit High Input. I haven't really paid attention to fuel consumption, but now that you mention it, I think I am visiting the gas station more often. What does the 'high input' mean in this case?

The P0113 code indicates that the Engine Control Unit (ECU) is receiving a signal from the IAT sensor that is higher than expected. This could indeed be caused by a defective IAT sensor, or potentially a wiring issue. Given the symptoms you describe and the error code, it seems increasingly likely that the sensor itself is the culprit. However, it's always difficult to be 100% certain without a thorough inspection. In your situation, going to a reliable workshop might be the best course of action. They can properly diagnose the fault and replace the sensor if needed.

Thanks a lot for your help! I suspected it might be the sensor, but I wasn't entirely sure. I took it to the workshop, and they confirmed it was a faulty intake air temperature sensor. The repair cost me 155€, including the new sensor and labor. The car is running smoothly again!
