1.
Remove EGR SV valve from vehicle. Refer to "Exhaust Gas Recirculation Solenoid Vacuum (EGR SV) Valve Replacement" in this section.
Measure
Measuring EGR SV Valve Resistance
^
Using a J39200, measure resistance between EGR SV valve terminals. Resistance when cold should be 37 - 44 ohms. Replace as necessary.
Checking For A Shorted SV Valve
^
Using a J39200, check for continuity between each terminal and the body of the EGR SV valve. Replace the EGR SV valve if continuity is
detected.
