- Turn ignition switch to "OFF" position. Disconnect Throttle Position Sensor (TPS) connector. Check resistance across terminals No. 1 and 3. See Fig 1. Resistance should be 3500-6500 ohms.
- Check resistance across terminals No. 1 and 2. Operate throttle valve slowly from idle position to full open position. Check that resistance changes smoothly in proportion to throttle valve opening. Resistance should change from 500 ohms to 3500-6500 ohms.
- If resistance is out of specification or does not change smoothly, replace the throttle position sensor.
