5 Symptoms That Indicate Your Car’s Throttle Position Sensor Is Failing.

One of the most frustrating repair issues for car owners is a faulty throttle position sensor (TPS). This device ensures that the ratio of air to fuel entering the engine is correct, and it’s essential for the car to run smoothly. Unfortunately, it’s not always easy to tell when a TPS is acting up, but there are a few common signs that can indicate you have an issue.

First, a delayed acceleration is a common sign of a bad TPS. If the time span between pushing down the gas pedal and the car actually starting to move is longer than usual, the problem may be the TPS. Similarly, stalling can occur regardless of whether the vehicle is idling or being driven. This can also be cause by issues with the transmission, or even a clogged air filter, so always consult with a qualified mechanic if you notice this issue.

Furthermore, if the vehicle begins to speed up or slow down on its own, especially on highways, that is a major indicator of a bad TPS. This usually happens when the accelerator is not beingcontrolled correctly and the sensor is not correctly reporting the accelerator position.

Finally, if your car’s check engine light is on, it could be caused by a malfunctioning TPS. Even if you don’t know the specifics of why the engine light is illuminated, it’s wise to take a car to a mechanic as soon as possible to diagnose the issue.

It’s worth noting that while a bad TPS can affect the vehicle’s performance, it doesn’t mean that the car is unsafe to drive. However, it’s important to get any TPS issues fixed immediately, or else further problems with the workings of the car could occur, such as rough idling, poor acceleration, or the engine running at an unusually high or low RPM.

To identify when a TPS is malfunctioning, there are a few signs to look out for. Delayed acceleration, stalling, the vehicle speeding up or slowing down on its own, and the check engine light being illuminated can all indicate a bad TPS. If any of these occur, it’s wise to take the car to a qualified mechanic for diagnosis and repair. With the right care, a malfunctioning TPS can be quickly rectified and your vehicle will be up and running smoothy again in no time.
