Throttle Position Sensor
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 Figure and Figure . If values are not as specified in table, adjust or replace TP sensor.
