REMOVAL AND INSTALLATION

Fuel Charging Wiring

Removal

  1. Perform Pre-Service Procedures as described in Fuel Charging System in the Removal and Installation portion of this section.

  1. NOTE: When the battery (10655) has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module (PCM) (12A650) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

    Disconnect battery ground cable (14301).

  1. Remove upper intake manifold (9424) as outlined in Section 03-01A.

  1. Remove strap attaching fuel charging wiring (9D930) to fuel injection supply manifold (9D280).

  1. Disconnect fuel charging wiring at:

  1. Remove fuel charging wiring from vehicle.

 

Installation

  1. Follow removal procedures in reverse order.

  1. Perform Post-Service Procedures as described in Fuel Charging System in the Removal and Installation portion of this section.

  1. Check for sensor function by performing EEC Self Test. Refer to Powertrain Control/Emissions Diagnosis Manual ODBII.
