TPS Adjustment: Galant

  1. Disconnect TPS connector. Using external ohmmeter, measure resistance between TPS terminals No. 3 and 4. See Figure . Insert .256" (.65 mm) feeler gauge between fixed speed adjusting screw and throttle lever.
  2. Loosen TPS mounting screws and rotate TPS fully clockwise. Ensure there is continuity between terminals No. 3 and 4. Rotate TPS counterclockwise until there is no continuity and tighten screws. Install Test Harness (MB991348 ) between TPS and harness connector.
  3. Turn ignition on. Using external voltmeter, measure TPS output voltage between terminals No. 2 and 4. See TPS SPECIFICATIONS  table. If voltage is not within specification, check harness and sensor. See SYSTEM/COMPONENT TESTS article in this section.
