Throttle Position (TP) Sensor
- Disconnect negative battery cable and TP sensor connector. See Fig 1 . Using ohmmeter, check resistance between indicated terminals. See THROTTLE POSITION (TP) SENSOR RESISTANCE table.
- If resistance is not as specified, adjust the TP sensor. See the ADJUSTMENTS article. If resistance is not as specified after adjustment, replace TP sensor. For further diagnostic procedures, see the TESTS W/CODES article.
