Fiat Linea Check Engine Light and Reduced Power

My 2021 Fiat Linea with a gasoline engine has an illuminated check engine light and reduced engine power at 210968 km. Error is stored and engine runs rough. I suspect a faulty intake air temperature sensor. Any insights?

Sounds familiar! I had almost the exact same symptoms in my old Opel Astra. Engine light, sluggish performance... Drove me nuts! Have you checked the sensor's temperature readings? Are they way off?

Thanks. How do I check the temperature readings, or what constitutes 'way off'?

I didn't do it myself. A friend with a diagnostic tool read the values; they were completely erratic. I'd say get it checked at a workshop; they'll pinpoint it quickly.

I took the car to a trusted workshop, and as suspected, the intake air temperature sensor was defective. The repair cost was 155€. The issue is resolved.
