What is the Throttle Position Sensor (TPS) of your Kia?

In short:
The TPS (Throttle Position Sensor) is the sensor that monitors the position of the butterfly valve of the throttle, allowing it to communicate with the computer so that it can adjust the injection and control the mixture of air and fuel. Some vehicles also include a similar sensor in the accelerator pedal called “APP sensor”.
The TPS sensor is located in the throttle body. If your vehicle has an automatic transmission, the TPS sensor also influences the control of the gears.

Signs that show that your Kia‘s TPS is faulty

  • Unstable idle speed
  • Lack of power
  • The car stalls or jerks
  • The “check engine” light comes on
  • In automatic cars, the gears may not work properly
