What is the throttle position sensor? 

The throttle position sensor (TPS) monitors the position of the throttle plate, which controls the airflow into the engine. By providing real-time feedback on how much the driver is pressing the gas pedal, the TPS helps the engine control unit (ECU) adjust the air-fuel mixture for optimal performance and efficiency.

Symptoms of a bad TPS throttle position sensor

A failing or malfunctioning Throttle Position Sensor (TPS) can manifest various symptoms, which may vary in severity. If you notice these situations, they may indicate a potential issue with the TPS:

  • Poor Acceleration: Sluggish or delayed response when pressing the gas pedal.
  • Rough Idle: An unstable or fluctuating engine idle.
  • Stalling: Unexpected engine shutdown, especially at stops.
  • Hesitation During Acceleration: Delayed acceleration after pressing the gas pedal.
  • Surging or Bucking: Jerking or lurching movements during acceleration or at constant speeds.
  • Inconsistent Idle Speed: Fluctuating engine idle speed.
  • Check Engine Light (CEL): Illumination of the Check Engine Light on the dashboard.
  • Poor Fuel Efficiency: Reduced gas mileage and increased fuel consumption.
  • Transmission Shifting Issues: Irregular or harsh shifting in automatic transmissions.
  • Limp Mode: The vehicle's computer may limit power and speed to protect the engine.

How to fix a throttle position sensor?

Fixing a faulty TPS often involves either cleaning the sensor or replacing it, depending on the severity of the problem.

Cleaning the TPS:

  • Disconnect the battery.
  • Locate and remove the TPS.
  • Clean it with an electronic contact cleaner.
  • Reinstall the TPS, reconnect, and reconnect the battery.

Replacing the TPS:

  • Disconnect the battery.
  • Remove the old TPS.
  • Get a matching replacement TPS.
  • Install the new TPS, reconnect, and reconnect the battery.
  • Calibrate if needed.
  • Test the vehicle for issues. If problems persist, consult a mechanic.
