Throttle Position Sensor

WARNING: This page is about a different car, the 1987 Toyota Supra. However, it is still accessible from the selected car via links, so may be relevant.

Turn ignition off and disconnect electrical connector at Throttle Position (TP) sensor. 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 table, adjust or replace TP sensor.
