When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle. What are signs of a bad Throttle Position Sensor? 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.
Can a bad throttle position sensor cause misfire?
You might wonder if a ‘bad throttle position sensor causes misfire’. If you notice engine misfire, stalling, or rough idling on parked or when you stopped, it could be a clear sign that your throttle position sensor is long gone. When you start your vehicle and allow it to run on idle, the RPM should be around 600-900 RPM.

A bad throttle position sensor can cause other issues on your car if left unattended. That's right! If the sensor is faulty, it will cause your car to shake heavily. Eventually, if this issue is left unattended it will put major stress on your motor and transmission mounts to the point where they will give out and will need replacement.
What does a throttle position sensor do?
The throttle position sensor is used to control the amount of gas that goes into the engine and thereby determine engine load and control vehicle speed. If it fails, it can result in automatic transmission hard-shifting issues.
How many customers have received a throttle position sensor replacement?
Average rating from 93 customers who received a Throttle Position Sensor Replacement. 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.
What are the symptoms of a bad throttle position sensor?
An unexplainable bucking and jerking in the vehicle.Sudden idle surges.Sudden engine stalling without any apparent reason.Hesitation while accelerating.Sudden surges in speed while driving on the highway.Intermittently flashing of check engine light for no apparent reason.Difficulties in changing gears.More items...
Can TPS cause rough idle?
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.
What does a faulty throttle position sensor cause?
The car might accelerate itself, hesitate to accelerate, or lack power when you are trying to accelerate. You may also experience difficulty in changing gears. There may be a dramatic drop in your cars' fuel economy as a result of a faulty throttle position sensor.
What should a throttle position sensor read at idle?
At idle is should be zero or a couple of degrees. Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open. You should see the percentage of throttle opening gradually increase to 100 percent at wide open throttle.
How do you reset a throttle position sensor?
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.

How do I adjust the idle speed on my electronic throttle body?
Disconnect the idle air adjustment valve by locating and disengaging the electronic connector that holds it to the throttle body. Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it.
What are the two sensors on a throttle body?
Among the two most important parts within the throttle body are the throttle body position sensor (TPS) and the throttle body temperature sensor. While they sound similar, they are indeed two individual parts that work together to efficiently mix fuel and air.
What happens if TPS is not calibrated?
If your TPS is faulty or uncalibrated, the sensor will be unable to accurately determine the position of the sensor. This will lead to a variety of symptoms, all of which are caused by the fact that the ECM is delivering the wrong air/fuel ratio to the cylinders thanks to the bad sensor.
How to tell if throttle position sensor is bad?
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. In most cases when your sensor goes bad, you will see the vehicle consuming more fuel than usual 4 Warning lights: The check engine light is designed to warn you when any sensor goes bad. If the check engine light turned on in your car, then it's important to check it out before the issue gets worse.
Where is the throttle body located?
The air will travel up the intake and it will reach your throttle body. The throttle body is a circular valve that’s located in between your air filter and Intake Manifold. In the old days, there was a wire attached to the gas pedal ...
What happens if a car sensor is faulty?
If the sensor is faulty, it will cause your car to shake heavily. Eventually, if this issue is left unattended it will put major stress on your motor and transmission mounts to the point where they will give out and will need replacement.
Why won't my car start if the throttle is stuck?
When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle.
What happens when throttle position sensor fails?
On the other hand, when the throttle position sensor fails, you will notice symptoms of bad thro ttle position sensor that can result in performance limitations, poor fuel economy, erratic idling , to name just a few.
Why is my throttle position sensor a false signal?
Since the throttle position sensor plays a significant role in proper air/fuel mixture for the combustion process, a false signal as a result of a lousy TPS will cause excess gas to inject into the cylinders and cause Lean/rich fuel mixture issues and poor fuel economy.
What is a TPS in a car?
Thousands of system components work together in harmony to make your vehicle engine provide peak performance the way it’s supposed to, and the throttle position sensor (TPS) is one of those components that are often overlooked. The throttle body is an essential component of fuel management that monitors the air that goes to the engine.

The average cost for a throttle position sensor is estimated to be $89 – $170. The service fee should be $40 – $60, while the parts should be around $49 – $110.
What is the purpose of a throttle body?
The throttle body is an essential component of fuel management that monitors the air that goes to the engine. The collected data that enables the throttle position sensor to monitor air into the engine determines precisely the amount of gas to inject into the engine at any given time.
What happens if your TPS is bad?
With a bad TPS in place, your vehicle may seem as though it doesn’t accelerate as it should, and hesitates, jerks, or won’t run smoothly. The vehicle engine may give a good acceleration but lacks engine power. On the other hand, it may suddenly accelerate itself while driving.
