I took off my front bumper cover and found this dangling. I don't see where it connects. Anyone know?

Thanks

It fits into a hole in your front bumper, behind the license plate fascia.

That sensor is important, and can cause LHM if damaged, so make sure it secured against damage and the wires protected from fretting.

Faulty ambient air temp readings can confuse the engine control module’s fuel calculation, so it may panic and reduce power.

Leaky boost hoses; bad MAF sensor; stuck EGR valve; bad MAP sensor; bad O2 sensor; ... and may result in loss of boost, imposed rpm limits, or a crank no-start event. Transmission faults like a bad shaft speed sensor reading or wheel speed sensor can lock the transmission down to 2nd/N/R/P The good news is the control modules store DTCs when thes events occur, and will share them if you ask nicely. :cheers:
