Have your vehicle checked for trouble codes to verify the source of the problem.

This isn’t always the case though, so don’t wait for the Check Engine Light to illuminate before you get any of the above symptoms checked out. The Check Engine Light may come on if you’re having issues with your TPS. Check Engine Light comes on, accompanied by any of the above behaviors This symptom often goes hand in hand with loss-of-power behavior. You may find that your car will accelerate, but not beyond a speed of 20 - 30 MPH. This is another failure mode of the TPS, which indicates that it is falsely limiting the power being requested with your accelerator pedal foot. Car accelerates, but won’t exceed a relatively low speed, or shift up

The TPS can also send bad input that ends up stalling the engine at any time. If the idling appears off, it means the computer is unable to identify the fully shut throttle. You don't want to wait to get this checked out! If you start to experience engine misfires, stalling, or rough idling when the car is stopped, it can also be a warning sign of a failing TPS. Engine won’t idle smoothly, idles too slowly, or stalls This gives the car an unintended burst of speed that occurs because the sensor cannot detect the closed position of the throttle.

When the car accelerates while driving, it usually means the butterfly valve inside the throttle has closed up and pops open suddenly when the driver presses on the accelerator. In these cases, the TPS isn’t providing the right input, the onboard computer cannot direct the engine to work properly. If these symptoms occur, there's a good chance you've got a problem with the TPS. On the flip side, it may be that your car suddenly speeds up while you’re driving, even if you haven’t pressed the accelerator. It may accelerate smoothly, but lack power. It may feel as though the car simply doesn't accelerate as it should, and jerks or hesitates as it picks up speed. Car won’t accelerate, lacks power when accelerating, or accelerates itself Here are some common symptoms of a bad or failing throttle position sensor to watch for: 1.

This is all best left to a professional mechanic who can provide you with a diagnosis, and then install the correct replacement part.

Replacing the TPS will include clearing relevant fault codes, and may require software reprogramming of the new TPS module to match other engine management software. Once the TPS begins to fail, even partially, you’ll need to replace it right away. This is intended to at least allow a driver to get off a busy highway in a safer manner. Also, most manufacturers provide a “limp home” mode of operation with reduced power if a failure is detected. In most cases, the Check Engine Light is illuminated if a TPS failure is detected. This sensor can fail gradually, or all at once. It can also cause problems when changing gears, or setting base ignition timing. The throttle position sensor can fail in several ways, all of which result in poor fuel economy at best, and performance limitations that may create a safety hazard for you and other motorists at worst. If the throttle position sensor and its other sensor partners do their jobs correctly, your car accelerates, cruises, or coasts smoothly and efficiently, as you expect, while maintaining optimum fuel economy. The collected data determines precisely how much fuel to inject into the engine at any given moment. The TPS signal is continually measured and combined many times per second with other data such as air temperature, engine RPM, air mass flow, and how quickly the throttle position changes. The TPS provides the most direct signal to the fuel injection system of what power demands are being made by the engine.

The throttle position sensor (TPS) is part of your vehicle's fuel management system and helps ensure that the correct mixture of air and fuel is delivered to your engine.
