Throttle Switch (Full Load Contact) Check

1. Connect ohmmeter across ECU connector terminals 12 and 17.
2. With throttle closed, resistance value should be infinite.
3. With throttle in full load position, resistance value should be 0 ohms. Switch over from throttle closed to full load position, should take place at approximately 3/4 total throttle travel.
4. If test results are not as specified, check resistance values directly at switch.
