Feb 12, 2023 · When the Throttle Position Sensor (TPS) goes bad, the Check Engine Light comes on and you may experience a rough idle. It also creates an unresponsive throttle, a lack of power, increased fuel consumption and can lead to gear shifting issues if it’s not resolved.

Jan 12, 2016 · Find vehicle issues early by learning the symptoms of a bad throttle position sensor. Catch a faulty TPS early with YourMechanic. 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.

A throttle position sensor, or TPS, monitors the position of the throttle valve in your engine, which controls the amount of air entering the engine based on how much you press the gas pedal. It sends real-time data to the engine control unit (ECU), allowing it to adjust fuel injection, timing, and air-fuel mixture for optimal performance, fuel ...

Nov 2, 2022 · The throttle position sensor (TPS) is one of the thousands of system parts that work in harmony to ensure that your car engine performs at the best it should, and it is also one of the parts that is frequently disregarded.

Feb 14, 2025 · While small and relatively simple, the throttle position sensor (TPS) is a critical component that tells your car’s computer how far you’re pressing the gas pedal, helping control fuel delivery to your engine. If your TPS fails, you may experience anything from annoying driveability issues to downright dangerous driving conditions.

Mar 10, 2023 · Experiencing erratic accelerations or rough idles in your car? These could be red flags of a bad Throttle Position Sensor (TPS). Understanding the signs and knowing how to address them is crucial to keep your car running smoothly.

The throttle position sensor measures the openness of the throttle valve and controls the airflow through the intake manifold of the engine. This sensor is also known as the TP or TPS sensor. The TPS sensor is generally installed in the throttle …

Mar 5, 2025 · Potentiometer-based TPS: This type of TPS comes with a variable resistor that is configured with the throttle shaft. When the throttle opened, the resistance of the potentiometer varied, which gave a voltage signal to the ECU. The ECU uses that signal for finding the position of the throttle and setting fuel injection. Hall effect-based TPS:

Sep 8, 2023 · The throttle position sensor (TPS) is a vital component in a car’s engine management system that plays a crucial role in ensuring proper engine performance and fuel efficiency. It is responsible for monitoring the position of the throttle valve and relaying this information to the engine control unit (ECU).
