Removal & Installation

  1. Remove air cleaner assembly. Disconnect electrical lead from TPS sensor. Remove attaching screws, lock washers, retainers, and TPS sensor. To install, reverse removal procedure. Adjust TPS to specification. See ADJUSTMENTS in this article. Use Loctite on TPS attaching screws.
  2. On model 220 TBI units, all 2.8L and 7.4L engines use a horizontal electrical connector on the TPS. All other engines with model 220 TBI units, use a vertical electrical connector on the TPS. The sensor mounting configurations are the same. When replacing a TPS ensure correct part number is used.
