EGR Valve: Service and Repair

Fig.3 EGR System:

NOTE: If the EGR system operates incorrectly, replace the entire EGR valve and transducer together. The EGR valve and electrical transducer (EET) are calibrated together.

NOTE: The EGR valve attaches to the rear of the cylinder head (Fig. 3). EGR transducer is attached to the air inlet duct.

REMOVAL
1. Remove EGR transducer from air inlet duct.
2. Disconnect vacuum supply tube from [1][2]EGR transducer solenoid.
3. Disconnect electrical connector from solenoid.
4. Remove air inlet duct.
5. Remove EGR tube to EGR valve screws.
6. Remove EGR valve mounting screws. Remove EGR valve and transducer.
7. Clean gasket surfaces. Discard old gaskets. If necessary, clean EGR passages.

INSTALLATION
1. Loosely install EGR valve with new gaskets.
2. Finger tighten EGR tube fasteners.
3. Tighten EGR tube fasteners to 11 Nm (95 in lb) torque.
4. Tightening EGR valve mounting screws to 22 Nm (200 in lb) torque.
5. Install air inlet duct.
6. Connect vacuum supply tube to solenoid.
7. Attach electrical connector to solenoid.
8. Install EGR transducer onto air inlet duct.
