EGR Control Solenoid: Testing and Inspection
COMPONENTS FOR REMOVAL AND INSTALLATION
VACUUM SWITCHING VALVE (VSV) FOR EGR INSPECTION
1. REMOVE VSV.
2. INSPECT VSV.
- Inspect VSV for open circuit
- Using an ohmmeter, check that there is continuity between the terminals.
Resistance: At 20°C (68°F): 38.5 - 44.5 Ohms)
- If there is no continuity, replace the VSV.
- 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.
- Inspect VSV operation.
- Check that air does not flows from port E to G.
- Apply battery voltage across the terminals.
- Check that air flows from port E to G.
- If operation is not as specified, replace the VSV.
3. REINSTALL VSV.
