WARNING: This page is about a different car, the 1985 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.

Turn Ignition Off and disconnect electrical connector at TPS. Insert a thickness gauge between throttle stop screw and throttle lever. Using an ohmmeter, check resistance values. See Fig 1. If values are not as specified in chart, adjust or replace TPS.
