How To Relearn Throttle Position Sensor

When you drive a car, you use your throttle to control the engine’s RPM. This is done by depressing the pedal and moving it up and down the scale. Throttle position sensors (TPS) keep track of this information and feed it back to the engine computer. When there’s a problem with the sensor, your car might not start or run properly. In this article, we will explain what a TPS is and how it works. We will also offer some instructions on how to diagnose and fix a TPS issue in a car.

What is Throttle Position Sensor?

Throttle position sensor is a sensor in an engine that senses the throttle position, or the percentage of open throttle, and sends this information to the engine control unit (ECU). The ECU uses this information to control fuel delivery, air mixture, and exhaust gas flow.

How to Relearn Throttle Position Sensor

If your car’s throttle position sensor is acting up, it might be time to take it off the rebuild or repair list and learn how to relearn it. Here’s how:

First, find the throttle position sensor connector on the driver’s side of your car near the firewall. It looks like a big, fat plug.

Second, use a multimeter to measure the resistance between each pin on the connector (see image below). If one of these readings is significantly different from the others, that means there’s an issue with the sensor itself and you’ll need to replace it. But if all readings are within spec, then you can proceed to Step 3.

In this step we’re going to “train” our new throttle position sensor by sending various signals to it from our computer. We’re doing this because our old sensor might have become damaged over time and doesn’t respond well to standard electrical signals anymore. To do this, we’ll first need to download and install a program called Throttle Position Sensor Disabler (TPSD).

Once TPSD is installed, open it up and click on the “Configure” button. This will bring up a screen where you can configure three important settings: Type of input port (Throttle), type of output port (Throttle Signal), and calibration type (Manual/Automatic). The last option is important because we want TPSD to decide which calibration


If your motorcycle doesn’t have a throttle position sensor, or if it’s not working properly, you might be able to fix the problem by learning how to re-learn the throttle position sensor. By doing this, you will be able to get your motorcycle back up and running as quickly as possible. If you’re unfamiliar with how a throttle position sensor works, or if you just need some general tips on fixing motorcycles, read on for more information.
