Throttle Position Sensor

Disconnect electrical connector from Throttle Position Sensor (TPS). Loosen TPS mounting screws. Connect ohmmeter between terminals IDL and E2. See Fig 1.
Apply vacuum to throttle opener. To set initial clearance, insert proper thickness feeler gauge between throttle stop screw and throttle lever. See V6 THROTTLE POSITION SENSOR ADJUSTMENT table.
With ohmmeter showing no continuity, rotate TPS clockwise until continuity exists. Tighten TPS mounting screws. Using specified feeler gauge, recheck adjusted clearance. Disconnect ohmmeter. Install electrical connector on TPS.
