EGR Valve: Service and Repair






Removal Procedure
1. Remove the Air Cleaner Outlet Resonator.
2. Disconnect the electrical connector to the EGR valve.
3. Remove the EGR valve bolts.
4. Remove the EGR valve.

Installation Procedure

Important: Be sure all gasket material is removed from the EGR mounting surface. Even a small amount of material may cause a DTC P0401 to set.

Note: Clear DTCs from the PCM any time either the PCM is reprogramed or the EGR valve is replaced, or anytime the ignition switch is turned on with the EGR valve electrical connector disconnected. This is due to the auto zeroing funtion of the PCM on the EGR pintle.

1. Install the EGR valve with the gasket.
2. Install the EGR valve bolts. Tighten EGR valve bolts to 22-30 Nm (16-22 lb ft).
3. Connect the EGR valve electrical connector.
4. Install the Air Cleaner Outlet Resonator.
