Throttle Position Sensor (TPS)
Turn ignition off and disconnect electrical connector at TPS. Note terminal identification. See Fig 1 through Fig 3 . Insert specified thickness feeler gauge between throttle stop screw and throttle ever. See TPS RESISTANCE SPECIFICATIONS table. Using an ohmmeter, check for resistance or continuity. Replace or adjust TPS if not within specification. See TPS RESISTANCE SPECIFICATIONS table.
