How To Fix Throttle Position Sensor

When it comes to your car, you want it to run smoothly and efficiently. This means keeping everything running as-intended, including the throttle position sensor. But if this component isn’t working correctly, your car may not run at its best. In this article, we will explore how to fix a throttle position sensor and get your car back on the road in no time. From adjusting the cable to testing the sensor itself, we’ll have you up and running in no time.

What is Throttle Position Sensor?

A throttle position sensor is a sensor used on motorcycles to monitor and adjust the engine’s output according to rider input. The sensor sends a signal to the engine controller that indicates how far open the throttle is. When the throttle is too wide open, the engine will run at high speeds and use more fuel; when the throttle is too close to idle, the engine will run at lower speeds and use less fuel.

How Does Throttle Position Sensor Work?

The throttle position sensor (TPS) is a device that senses the throttle position of an engine and provides information to the engine control unit. If the TPS becomes damaged, it may not provide accurate readings, which can cause the engine to run poorly or not at all. In addition, if the TPS is not working properly, it can cause the engine to over-rev or stall.

To check whether or not the TPS is causing any problems, first you will need to remove the air filter. Next, disconnect the battery cables and ground cables from the TPS. Finally, disconnect the connector from electrical connector A on your engine receiver assembly.

Once you have removed these items, you can begin testing them. First, connect a voltmeter across each of the black terminals on the TPS and see if there is an output. If there is no output, then your TPS may be defective and needs to be replaced. If there is an output, then your TPS may just need some adjustment and should be re-installed without replacing it.

If you do find that your TPS is causing problems with your engine performance, then it may be necessary to replace it. However, before doing so, make sure to consult with a qualified mechanic so that he or she can properly diagnosis and fix any issues that may be caused by faulty circuitry in your engine control unit.

How to Fix Throttle Position Sensor

If your car’s throttle position sensor isn’t working properly, the car will probably not be able to reach its full speed. There are a few ways to fix this problem. One way is to replace the faulty sensor. Another option is to adjust the ECU settings so that the car can use a different power source to help it reach its maximum speed.


If you’re experiencing problems with your throttle position sensor, there are a few things you can do to try and fix the issue. First, make sure that the throttle is shut off and the engine is stopped before trying to diagnose or repair the sensor. Next, remove any carbon or debris from around the throttle body. Finally, clean all of the connectors on the engine wiring harness and sensor connector using a wire brush and ATF (automatic transmission fluid). If these steps don’t fix your problem, then you may need to replace your throttle position sensor.
