Throttle Position Sensor (TPS) Test
WARNING: This page is about a different car, the 1990 Toyota Land Cruiser and 1989 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition off. Unplug electrical connector at TPS on throttle body. Note terminal identification. See Fig 1. Insert specified thickness feeler gauge between throttle stop screw and throttle lever. See TPS RESISTANCE SPECIFICATIONS table. Using an ohmmeter, check for resistance or continuity. Replace or adjust TPS if not within specification.
