Throttle Position Sensor Test
WARNING: This page is about a different car, the 2001 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect throttle position sensor connector. Check resistance between sensor terminals No. 1 and 3. See WIRING DIAGRAMS . Resistance should be 5350-7350 ohms.
- Connect an analog ohmmeter between sensor terminals No. 1 and 3. Operate throttle valve slowly from idle to wide open throttle. Resistance should change smoothly as throttle is opened and closed. Replace and adjust throttle position sensor as necessary. See ON-VEHICLE ADJUSTMENT article in ENGINE PERFORMANCE.
