01Introduction

  • The throttle position sensor (TPS) is located on the throttle body.
  • It is responsible for monitoring the position of the throttle valve.
  • The TPS sends signals to the engine control unit (ECU) to adjust the fuel and air mixture.
  • A faulty TPS can cause various performance issues such as hesitation, rough idle, and poor throttle response.

02Tools Needed

  • Socket wrench set
  • Multimeter
  • Electrical cleaner
  • Safety goggles
  • Latex gloves

03Step 1: Preparation

  • Ensure the motorcycle is parked on a flat and stable surface.
  • Wear safety goggles and latex gloves to protect your eyes and hands.
  • Make sure the engine is off and cool to the touch.
  • Locate the throttle body on your motorcycle.

04Step 2: Disconnect the TPS

  • Using a socket wrench, loosen the bolts securing the TPS to the throttle body.
  • Carefully disconnect the electrical connector from the TPS.
  • Take note of the position and orientation of the connector for reassembly.

05Step 3: Test the TPS with a Multimeter

  • Set your multimeter to the voltage testing mode.
  • Connect the multimeter probes to the TPS connector terminals.
  • Turn on the ignition key without starting the engine.
  • Gradually open and close the throttle while observing the voltage readings on the multimeter.
  • The voltage should increase or decrease smoothly as the throttle opens or closes.
  • Any sudden jumps or fluctuations in voltage indicate a faulty TPS that needs to be replaced.

06Step 4: Clean and Reinstall the TPS

  • Spray electrical cleaner on a clean cloth.
  • Gently wipe the TPS and throttle body to remove any dirt or debris.
  • Ensure the TPS and throttle body are completely dry before reinstallation.
  • Reconnect the electrical connector to the TPS, ensuring proper alignment.
  • Tighten the bolts securing the TPS to the throttle body.
  • Double-check all connections and ensure they are secure.

07Conclusion
