Throttle Position Sensor (TPS)
- Turn ignition off. Disconnect electrical connector from TPS on throttle body. Note terminal identification. See Fig 1 and Fig 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.
NOTE:
Some models require that vacuum be applied to throttle opener before checking TPS. See appropriate TPS RESISTANCE SPECIFICATIONS table.
