Throttle Position Sensor Test
- Disconnect throttle position sensor harness connector. Check resistance between sensor terminals No. 1 and 4. Refer to the WIRING DIAGRAMS . Resistance should be 3.5-6.5 ohms.
- Connect an analog ohmmeter between sensor terminals No. 2 and 4. Operate throttle valve slowly from idle to wide open throttle. Resistance should change smoothly as throttle is opened and closed. Replace throttle position sensor as necessary.
