Throttle Position Sensor (TPS): Removal

  1. Remove TPS electrical connector. Remove air cleaner and throttle body assembly. Turn throttle body upside down and support assembly to prevent damage to injector connectors. Using a 5/16" drill bit, drill completely through both TPS access holes in base of throttle body to remove spot welds holding screws in place.
  2. Remove and discard TPS attaching screws. Remove lock washers and retainers. Remove TPS from throttle body, noting location of TPS pick-up lever in relation to throttle shaft lever tang for installation reference.
