The ambient temperature sensor gauge inside the car fluctuates dramatically between -38 and 100 degrees. It's not stable. I have replaced both sensors what could the problem be?
My car has 214000 miles.
My car has an automatic transmission.
The ambient air temperature sensor is located in front of the a/c condenser in the center of the vehicle mounted just below the hood latch on the support bracket. The sensor will give temperature reading s from about -40 to 240 degrees F. If you are getting display readings that are jumping between -38 and 100 then you may have a sensor wiring that is opening up or the connection has corrosion in it. Have a mechanic from YourMechanic come and check the wiring by monitoring the display while moving the wiring slightly to see if the open circuit can be found. You most likely have a wire connection to the sensor that needs cleaned and a small amount of dielectric lube put in connector to stop the connection corrosion.
