  4. Loosen the throttle position sensor mounting bolts and turn the TP Sensor body fully counterclockwise.
  5. In this condition, check that there is continuity between terminals 1 and 2.
  6. Slowly turn the throttle position sensor clockwise until you find a point at which there is no continuity between terminal 1 and 2. Then, tighten the throttle position sensor mounting bolt securely.
  7. Connect the throttle position sensor connector.
  8. Connect the scan tool to the data link connector in the fuse box.
  9. If the scan tool is not used, connect a voltmeter between throttle position sensor connector terminals 1 (sensor ground) and 3 (sensor output) using pin.
    NOTE:
    • Do not disconnect the TP Sensor connector.
    • Use a digital type voltmeter to obtain an accurate value.
  10. Turn the ignition switch "ON."
    NOTE: Do not start the engine.
  11. Check the throttle position sensor output voltage.

    Throttle position sensor output voltage: 250~800 mV

  12. If the voltage is out of specification, check the throttle position sensor and associated harnesses.
  13. Remove the feeler gauge.
  14. Turn the ignition switch OFF.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
