What are signs of a bad Throttle Position Sensor? 1 Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn't step on the gas. 2 Unstable Engine Idle: Faulty position sensors can cause sporadic idle conditions due to fluctuating airflow. If you see your car misfiring, Idling rough, or stalling out while you drive then you definitely want to have a professional check out that sensor. 3 Unusual fuel consumption: The TPS works alongside other sensors to ensure that your ride is driving smoothly and efficiently. When these sensors start to go bad then other modules might start working differently to compensate for lack or abundance of airflow.
