How can the Throttle Position Sensor be checked and adjusted with the throttle body installed on the plenum on Toyota MR2?

The TPS can be checked with the throttle body installed on the plenum, although clarity is enhanced by performing the following steps on a workbench. First, loosen the spring clip with a screwdriver and unplug the TPS electrical connector. Next, insert a feeler gauge of the specified thickness between the throttle stop screw and the throttle stop lever. Using an ohmmeter, check the resistance between each terminal and compare the readings to the specified resistance values; if any terminals fail, the TPS will need adjustment or replacement. To adjust or replace, remove the throttle body and loosen the two sensor mounting/adjustment screws. Insert a 0.47 mm (0.0185 in) feeler gauge between the throttle stop screw and the stop lever, then connect the ohmmeter to terminals IDL and E2. Gradually turn the sensor clockwise until the ohmmeter deflects, then tighten the sensor mounting/adjustment screws. Recheck continuity between terminals IDL and E2 by inserting a 0.35 mm (0.0138 in) feeler gauge; there should be continuity, and inserting a 0.59 mm (0.0232 in) feeler gauge should show no continuity. If the TPS fails either check, it must be replaced. Finally, installation is the reverse of removal, ensuring the new TPS is adjusted before installing the throttle body.
