Symptoms of a Defective TPS
The function of the throttle position sensor is to supply information to the car's computer about the position of the car's throttle. It contains electro-mechanical parts, which are prone to weathering. A malfunctioning TPS can result in improper or no data being fed to the car's computer, which monitors engine performance, in respect to the fuel efficiency of the car.
A TPS usually detects heat, light, and even moisture. It takes all the necessary measurements and sends it over to the Electronic Control Module. The biggest problem with a TPS is that it's so small and intricate, that repairing it is almost always out of the question. But the good news is, a decent TPS isn't that hard on your wallet.
One unique thing about TPS failure is that all the symptoms may show up at the same time. It doesn't mean that they show individually, but it often happens that you'll notice more than just one sign.
The 'Check Engine' Light is On
This is the first thing that you'll notice. The light is meant to tell you, the driver, that something is wrong with either a component of the car, or its sensor. It's always advisable to get your car checked out by a mechanic as early as possible if this light is on.
Bucking and Jerking/Hesitation while Accelerating
Another common symptom related to a bad TPS is the jerking of the car, especially when accelerating. Without proper inputs from the TPS, the on-board computer is unable to guide the engine to work at optimum levels. (this is why I wanted to replace mine in the first place...It would happen at around 55 MPH and the truck would kinda stutter or jerk while I was accelerating to get up to speed)
Idle Surging
This problem usually comes in conjunction with the above one. Similar to getting jerks while accelerating, with a faulty TPS, the computer cannot tell if the throttle is fully shut when the car is idling.
Sudden Stalling of the Engine
This can happen anytime, without any kind of warning, while driving or idling. The TPS can give a bad input, prompting the engine to stall.
Sudden Surge in Speed While Driving on the Highway
This is a particularly hazardous situation. What usually happens is that at high speeds, the butterfly valve inside the throttle may close up, and if the driver pushes on the pedal harder, the valve 'pops' open suddenly, giving the car an unintentional burst of speed. All of this happens if the sensor is unable to detect the closed position of the throttle.
Hope this helps
