Throttle Position Sensor Adjustment

1992 Toyota Pickup Base, W55SECTION Throttle Position Sensor Adjustment
  1. 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 1-29.
  2. Apply vacuum to throttle opener (if equipped). See Fig 1-29. To set initial clearance, insert proper thickness feeler gauge between throttle stop screw and throttle lever. See 4-CYLINDER THROTTLE POSITION SENSOR ADJUSTMENT  table.
  3. 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.
