Transmission Fluid Temperature Sensor (B) Circuit High

The ATF (Automatic Transmission Fluid) Temperature Sensor converts the fluid temperature into a resistance value. The sensor resistance changes with the transmission fluid temperature. As the temperature becomes higher, the sensor resistance decreases. The Transmission Control Module (TCM) monitors the ATF (Automatic Transmission Fluid) Temperature Sensor signal. The TCM sets the OBDII code when the ATF (Automatic Transmission Fluid) Temperature Sensor signal is out of factory specifications.

Cause:
Faulty Transmission Fluid Temperature Sensor
Transmission Fluid Temperature Sensor harness is open or shorted
Transmission Fluid Temperature Sensor circuit poor electrical connection

Symptoms:
Check engine light
