Throttle Position Sensor

  1. Turn ignition off. Disconnect electrical connector from Throttle Position Sensor (TPS) on throttle body. Note terminal identification. See Fig 1 and Fig 2.
    NOTE: Some models require that vacuum be applied to the throttle opener before checking TPS. See appropriate TPS RESISTANCE SPECIFICATIONS .
  2. Insert specified thickness feeler gauge between throttle stop screw and throttle lever and check resistance or continuity. See appropriate TPS RESISTANCE SPECIFICATIONS  table. Replace or adjust TPS if not within specification.
