P0712 Buick Code - Transmission Fluid Temperature Sensor Circuit Low Voltage
Quick Answer
The Automatic Transmission Fluid Temperature (TFT) sensor is a resistor, or thermistor, which changes value based on temperature. Common causes include Faulty Control Solenoid Valve Assembly, Control Solenoid Valve Assembly harness is open or shorted, Control Solenoid Valve Assembly 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.
