Throttle Position (TP) Sensor

1. Turn ignition off. Disconnect TP sensor wiring harness connector. Rotate throttle to wide open position. Measure resistance between terminals "A" and "B". See Fig 1 . Resistance should be about 5 ohms.
2. Rotate throttle to closed position. Again, measure resistance between terminals "A" and "B". See Fig 1 . Resistance should be about 1 ohm. If resistance is not as specified, loosen TP sensor screws. Adjust TP sensor until resistance is within specification.
