Fuel Delivery and Air Induction: Service and Repair

Intake Manifold Diagnostic Plate (P/N J-39185):

Chart A-8 Intake Manifold Diagnostic Plate Installation Procedure:

Circuit Description
Due to the inaccessibility of the fuel rail, fuel injectors, fuel rail pressure test fitting and the knock sensor as well as the engine coolant sensor, it will be necessary to install the Intake Manifold Diagnostic Plate to be able to run the engine with the plenum assembly removed.

Diagnostic Aids
^ The ground stud is provided for the engine control module ground so as to not create any additional driveability problems while testing.
^ Bolt hole "D" is to mount the electronic ignition assembly to the manifold plate.
^ It is important to clear any malfunction diagnostic trouble codes after the manifold plate is removed. Retest the vehicle to insure no malfunction diagnostic trouble codes reset.
^ The exhaust gas recirculation block plate is used to cover the opening in the exhaust manifold where the exhaust gas recirculation exhaust tube originally was connected.
