I recently had my front bumper on my '11 Mustang (automatic w/ 37,000 miles) repainted and the fog lenses replaced. I noticed the external temperature display has been reading higher than the actual outside temperature. As I understand it the ambient temperature sensor clips onto the front bumper. I can't see the sensor when looking through the hood latch opening. All I see is the wire harness going underneath the radiator. I think they stuck the sensor under the radiator instead of clipping it properly to the bumper. Does this temperature sensor effect how the engine runs? Is the data feed into the computer or is it just used to display the external temperature in the information display area? Thank you.

does it doesnt affect your engine. you can remove the temperature sensor, but dont drive your car. turn off car and turn if back on without that external temperature sensor. if something doesnt look right, consult your owners manual, but to be sure ask your car dealership for this information they will be happy to help. here at carkiller we help people with the help of the public to help you find an easy repair for free. feel free to help us further diagnose your vehicle, no problem is too big or small. here at CARKILLER, we make sure youre problems are solved. please provide us with more analysis of your diagnotics
The engine management temperature used should be from a temp sensor in the airbox. Yea, they may have forgot to put back in the correct place, slide under car bumper and give it a look, you should be able to get it away from the radiator. Also, unplug and replug the temp connector ( if a slight bad contact can cause it to increase).
No it should not affect engine performance. I've never seen one installed on a bumper though. Usually they are behind the grill, in front of the radiator, down low. They're not very accurate and they always read high, especially when you're not moving. The faster you go, the closer it is to actual outside temp.
