EGR Valve: Service and Repair
REMOVALIf the EGR system operates incorrectly, replace the entire EGR valve and transducer together. The EGR valve and electrical transducer are calibrated together.
1. Remove the air cleaner lid, disconnect the inlet air temperature sensor and makeup air hose.
2. Remove the negative battery cable.

INSTALLATION
If the EGR system operates incorrectly, replace the entire EGR valve and transducer together. The EGR valve and electrical transducer are calibrated together.
1. Connect vacuum supply tube to solenoid.
2. Attach electrical connector to solenoid.
3. Install EGR transducer into the bracket and snap closed.
4. Loosely install EGR valve with new gaskets.
5. Finger tighten EGR tube fasteners.
6. Tighten EGR valve mounting screws to 22 N.m (195 in. lbs.) torque.
7. Tighten EGR tube fasteners to 11 N.m (97 in. lbs.) torque.
NOTE: Make sure that the hoses are routed away from the hot EGR tube and Valve and clipped.
8. Install the negative battery cable.
9. Install the air cleaner lid, connect the inlet air temperature sensor and makeup air hose.
