TPS Adjustment
WARNING: This page is about a different car, the 1994 Mitsubishi Diamante. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Ensure basic idle speed is set to specification before adjusting TPS. See BASIC IDLE SPEED
under IDLE SPEED & MIXTURE. Perform all adjustments with engine at normal operating temperature, front wheels in straight-ahead position, cooling fan and all accessories off, and transmission in Park or Neutral.

- Disconnect TPS connector. Using external ohmmeter, measure resistance between TPS terminals No. 3 and 4. See Fig 1 . Insert .025" (.65 mm) feeler gauge between fixed speed adjusting screw and throttle lever.
- 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.
- 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.
