Problem overview

Some Pontiac Torrent owners report experiencing reduced engine power due to the activation of the traction control light, which is often linked to sensor issues. This warning indicates that the traction control system has detected a loss of traction or a potential malfunction in the sensors monitoring wheel speed and other critical data. A faulty sensor can cause the traction control system to engage unnecessarily, leading to a decrease in engine power to prevent wheel spin and maintain vehicle control. Common sensors involved include wheel speed sensors, steering angle sensors, and yaw sensors. It is crucial for owners to have their vehicles inspected by a qualified mechanic to diagnose the specific sensor issue causing the traction control light to activate and the subsequent reduction in engine power. Promptly addressing these sensor issues is essential to ensure the proper functioning of the traction control system and to maintain the vehicle's safety and performance.
