Ambient Temperature Sensor Circuit

CIRCUIT DESCRIPTION

The ambient temperature sensor sends the outside temperature signal to the ECM. The ECM transmits the signal to the skid control ECU as a communication signal. The skid control ECU controls the tire pressure warning system, depending on the changes in the outside temperature.

HINT: The signal sent from the ambient temperature sensor is also used in the A/C.
