  1. Manufacturer does not list procedure for Throttle Position (TP) sensor adjustment. Only information available is for checking resistance of TP sensor.
  2. Disconnect electrical connector from TP sensor. Note electrical terminals on TP sensor. See Fig 10. Apply vacuum to throttle opener located on throttle body. See Fig 10.
  3. Using ohmmeter, check resistance between specified terminals in relation to throttle position. See THROTTLE POSITION SENSOR RESISTANCE  table. Replace components as necessary if resistance is not within specification.
