- Disconnect electrical connector from EGR VSV. See EGR VSV LOCATIONS table. See Figure. Using ohmmeter, check that continuity exists between electrical terminals on EGR VSV and resistance is 33-39 ohms at 68°F (20°C). Replace EGR VSV if no continuity exists, or resistance is not within specification.
- Ensure no continuity exists between each electrical terminal and body of EGR VSV body. Replace EGR VSV if continuity exists between electrical terminal and body of EGR VSV.
- To test EGR VSV operation, apply air pressure to port "E". Ensure no air flows from port "F". Perform STEP 1 in illustration. See Fig 1. Apply battery voltage and ground to electrical terminals on EGR VSV.
- Apply air pressure to port "E". Ensure air flows from port "F". Perform STEP 2 in illustration. See Fig 1. Replace EGR VSV if defective.
