How To Adjust The Grand Vitara TPS

The TPS, on the 2.5L Grand Vitara (Chevy Tracker) covered by this tutorial, has to be adjusted if removed and replaced.

The adjustment procedure is easy and below you'll find it explained in a step-by-step way:

  1. Tap into the RED/GRN wire of the TPS with the red multimeter test lead.
    • The TP sensor must remain connected to its connector during the whole adjustment procedure.
  2. Ground the black multimeter test lead on the battery negative (-) terminal.
  3. Turn the key to the ON position but don't crank or start the engine.
  4. Your multimeter should read 0.35 to 0.65 Volts DC with the throttle plate closed.
    • If the multimeter does not read 0.35 to 0.65 Volts DC, then the TPS is not adjusted to specification.
  5. To adjust the TPS:
    • Loosen the TPS screws.
    • Rotate the TPS till your multimeter registers 0.35 to 0.65 Volts and tighten the screws.
  6. After tightening the TPS screws, check the voltage reading on the RED/GRN wire to make sure it's within the indicated specification.
  7. After the TPS adjustment is done, reset the fuel injection computer by disconnecting the battery negative cable from the battery for about 10 seconds. This is a very important step for the computer to recognize the new closed throttle plate angle voltage value as 0 degrees!
