Throttle Position Sensor Adjustment
- Disconnect electrical connector from Throttle Position Sensor (TPS). Loosen mounting screws. Connect ohmmeter between terminals IDL and E1 (MR2 2.2L with M/T) or E2 (all others). See Fig 1-Fig 4 .
- Apply vacuum to throttle opener (if equipped). See Fig 1-Fig 4 . To set initial clearance, insert proper thickness feeler gauge between throttle stop screw and throttle lever. See the 6-CYLINDER THROTTLE POSITION SENSOR ADJUSTMENT table.
- With ohmmeter showing no continuity, rotate TPS clockwise until continuity exists. Tighten mounting screws. Using specified feeler gauge, recheck adjusted clearance. Disconnect ohmmeter and install electrical connector on TPS.
