Taurus Intake Air Temperature Sensor Fault

I drive a Taurus too, and I had something similar happen. Reduced power and rough running. What readings were you getting from the IAT sensor? Was it showing crazy high or low temperatures, or just a nonsensical value?

The diagnostic tool displayed an implausible temperature reading, way outside the expected range, even with a cold engine. Did you replace the sensor yourself, or did you go to a professional?

Yep, that sounds very familiar. Mine was doing the same thing. I'm not much of a mechanic, so I ended up taking it to a workshop. They confirmed it was the IAT sensor and replaced it. It's worth getting checked by someone who knows what they're doing.

I appreciate the insight. I had a hunch it needed professional attention. The workshop just called; it was indeed the IAT sensor as suspected. Repair cost 155€. Thanks again for sharing your experience!
