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.
How much does a throttle position sensor cost?
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 is the low speed of a TPS?
In such a case, your vehicle will idle and accelerate nice and smoothly but won’t exceed a certain low-speed of 25-35 MPH.
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.
