The plastic panels (the fender liners) are gone on both sides and no sign of any wires to be seen anywhere.
There are no wires whatsoever no connector!! The display shows Temp is -40F. A mechanic told me this goes into the computer and that may affect the engine (timing,fuel-mixture) although it runs just fine.
P.S. We have +100F here in Tucson.
I don't think so. If u study the electrical circuits, the OAT circuit begins and ends in the instument cluster. Therefore, no bearing on the engine performance.
The DME/ECU brain has it's own temperature sensor that gets it's signals from the engine, along with air temp measurements from the Mass Airflow meter ... definitely not from the OAT
