Insignia charge air temperature sensor issue

My 2020 Vauxhall Insignia gasoline engine has a check engine light and reduced power. I hear a whistling noise and loud hissing during acceleration. There's also an error for the charge air temperature sensor, and the car has 42163 km. Anyone seen this?

Sounds familiar. I had a similar issue with my Insignia, though I can't recall the exact error code. Check the cable and plug connection of the charge air temperature sensor. Is the temperature fluctuation high when reading the sensor values?

Thanks. I'll inspect the cable and plug. Could you explain the temperature fluctuation you mentioned? What range would be abnormal? I want to read the sensor values correctly.

Yeah, I remember that the values were all over the place. After checking everything myself I took it to a local workshop. They also found the cable or plug to be faulty and quoted around 95€ for the repair. I think it's best to leave it to a professional.

Thanks. I followed your suggestion and took it to a workshop. The diagnostic confirmed a defective connection at the charge air temperature sensor. The repair cost me 95€, as you predicted. Everything is working now.
