Throttle Position (TP) Sensor

Disconnect negative battery cable and TP sensor connector. See Fig 1 , Fig 2 or Fig 3 . Using 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 appropriate TESTS W/CODES article.
