Ulysee Charge Air Temperature Sensor Issue

Hi, I have a 2023 Fiat Ulysee diesel and the check engine light is on. I'm experiencing reduced engine power and a whistling noise, especially when accelerating, almost like a loud hissing. The error code points to the charge air temperature sensor. Mileage is at 179386 km. Anyone else had this?

A 2023 Fiat Ulysee diesel owner reported a check engine light, reduced engine power, and a whistling noise, with an error code indicating an issue with the charge air temperature sensor. A similar case suggested checking the cable and plug connection to the sensor. The problem was resolved by addressing the cable issue at a workshop.

Did this summary help you solve your problem?

I have a Ulysee too and had similar symptoms. Check the cable and plug connection to the temperature sensor. That was the culprit in my case.

Thanks! Where exactly is that located? Is it easy to get to?

It's near the airflow sensor. Honestly, I'd recommend getting a workshop to check it. They should be able to diagnose it quickly.

Thanks, I appreciate the advice. Took it to the workshop, and it was indeed the cable. 95€ and all sorted.
