AutoCodes – Generic – P0712

P0712 Code - Transmission Fluid Temperature Sensor 'A' Circuit Low Input

Quick Answer

The ATF (Automatic Transmission Fluid) Temperature Sensor converts the fluid temperature into a resistance value. Common causes include Faulty Transmission Fluid Temperature Sensor, Transmission Fluid Temperature Sensor harness is open or shorted, Transmission Fluid Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0712 Description

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.
