Fusion Charge Air Temperature Sensor Issue

My 2005 Ford Fusion, gasoline engine, with 115036 km is having issues. The check engine light is on, engine power is reduced, and there's a whistling noise and a loud hissing sound when accelerating. Error memory says charge air temperature sensor malfunction. I suspect a defective cable or plug connection. Anyone seen this?

Sounds familiar. I've got a Ford Fusion as well. I had almost the same symptoms a while back - check engine light, loss of power, and a weird hissing noise. Did you check the sensor's wiring harness for any obvious damage or corrosion?

Thanks. Is there a specific area on the wiring harness where damage is more likely?

Honestly, I didn't get too deep into diagnosing it myself. I'd suggest a professional look, just to be safe. It could save you a lot of time and potential headaches. The mechanic can pinpoint the exact issue and repair it properly.

Understood. I appreciate your advice. I took it to my workshop. Turns out the cable connection for the charge air temperature sensor was defective, just like you suspected. 95€ later and it's all sorted.
