Throttle Position Sensor

INSPECTION

1. Unfasten the throttle sensor connector. Connect a suitable ohmmeter to the sensor as shown in the illustration.
2. Open the throttle valve and observe the resistance readings. Normal readings are as follows:

   Throttle opening A to B:

   • Idle position: approximately 1k ohms
   • Full open position: approximately 4–6k ohms

   Throttle opening A to C:

   • Idle position: approximately 4–6k ohms
   • Full open position: approximately 4–6k ohms

3. Reattach the connector. If the resistance readings are not as specified, adjust the throttle sensor.
