Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission Fluid Temperature (TFT) sensor is located by the control valve body of the transmission.

When the transmission fluid is cold, the sensor resistance is high. As the transmission fluid warms up, the sensor resistance decreases. The PCM monitors the TFT circuit.

When the PCM detects a continuous short to ground in the TFT circuit, then DTC P0712 sets.

DTC P0712 is a type A DTC.
