Disconnect TPS connector. Using hand vacuum pump, apply 20 in. Hg vacuum to throttle opener to move throttle lever to idle position. Using ohmmeter, check resistance between specified terminals of TPS connector with proper shim thickness gauge inserted between throttle valve lever and stop screw. See Figure . Also, refer to the THROTTLE POSITION SENSOR (TPS) RESISTANCE table. Adjust sensor if reading are not as specified.
