Malibu Charge Air Temperature Sensor Error

My 2014 Chevrolet Malibu diesel has a charge air temperature sensor error. The check engine light is on, and there's reduced engine power. I also hear a whistling noise and a loud hissing when accelerating. The error is stored in the memory. Mileage is at 32396 km. Any ideas?

I have a Malibu too, and I had similar symptoms. Check Engine light, whistling. Was it throwing any specific codes related to airflow or intake air temperature? Did you check the air intake duct for any obvious cracks or loose connections?

I haven't checked the intake duct yet, but that's a good idea. About the codes, could it be related to a defective cable or plug connection?

Yeah, a bad connection could definitely cause those symptoms and trigger the sensor error. Given the hissing sound, though, it might be more than just a loose wire. If you're not comfortable digging in, I'd suggest taking it to a workshop.

Thanks. Turns out it was a defective cable connection as suspected. Workshop charged me 95€ to fix it.
