Throttle Sensor
- To check and adjust throttle sensor, proceed as follows. Warm up engine then turn it off. Connect voltmeters to checking connector (Green) as shown in Fig 1 .
- Turn ignition switch on and check to see if current flows to one of the voltmeters. If current flows to both voltmeters or does not flow at all, turn throttle sensor adjusting screw until current flows to one of the voltmeters.
- If current flows to both voltmeters, turn adjusting screw counterclockwise. If current does not flow at all, turn adjusting screw clockwise. After adjusting, install cap onto adjusting screw.
- Disconnect connector for throttle sensor. Connect an ohmmeter to throttle sensor as shown in Fig 2 . Open throttle valve and observe ohmmeter reading. At idle reading should be about 1000 ohms. Wide open reading should be about 5000 ohms.
