EGR Control Solenoid: Testing and Inspection

INSPECTION





1. REMOVE EGR VSV ASSEMBLY
Disconnect the connector and 2 vacuum hoses, and remove the 2 bolts and EGR VSV assembly.





2. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, measure the resistance between the terminals.

Resistance:
33-39 ohms at 20°C(68°F)

If resistance is not as specified, replace the VSV.





3. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.
4. INSPECT VSV OPERATION





(a) Check that air flows from port E to port G.





(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from port E to the filter. If operation is not as specified, replace the VSV.
5. REINSTALL EGR VSV ASSEMBLY
(a) Install the EGR VSV assembly with the 2 bolts.

Torque:8 N.m (80 kgf.cm 71 in.lbf)

(b) Connect the connector and 2 vacuum hoses to the VSV.
