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