What is TPS sensor problem?
What happens when my throttle position sensor goes bad. When a TPS goes bad, then the car’s throttle body won’t function properly. 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 does the throttle position sensor ( TPS ) do?
Throttle Position Sensor (TPS) The job of the TPS is to tell the computer what the position of the throttle is. This sensor is vital in helping the computer determine if the throttle is closed or open; or how fast the throttle is opened or closed.
What happens if you have a bad TPS 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. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn’t step on the gas.
Can a bad throttle position sensor be ignored?
A throttle position sensor consists of mechanical parts which may become worn and require replacement. A malfunctioning throttle position sensor will relay wrong data to your car’s computer. A faulty throttle position sensor should not be ignored.
Are there trouble codes associated with the TPS?
There are trouble codes that are associated with the TPS. One code will set if the TPS voltage is too high when the computer expects to see it lower. Another code will set if the TPS voltage is lower than the computer expects to see.
What does the Check Engine light on a TPS sensor mean?
If your TPS sensor has turned on the check engine light, you may need to clear it with a scanner. The check engine light will not always go away after replacement of the TPS. The TPS monitors the position of the throttle valve, which regulates how much air is supplied to the engine.

What is the voltage of a TPS sensor?
The potentiometer type of TPS is a variable resistor, effectively supplying a gradually increasing supply of voltage to the computer as the throttle is gradually opened. Usually the voltage operating range is from about one-half a volt at idle, to five volts at wide-open throttle.
How does the TPS monitor the throttle position?
The TPS monitors the position of the throttle valve, which regulates how much air is supplied to the engine. Your gas pedal is attached to the the throttle valve (either electronically or mechanically) — as you press the pedal farther in, the valve opens more.
