EGR Control Solenoid: Testing and Inspection

EGR Solenoid Vacuum (SV) Valve (California Emissions Only)

Tools Required:

J39200 Digital Multimeter
J36169 Fuse Jumper Wire

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.

Checking EGR SV Air Flow:

2. Blow air through port "E" of the valve and make sure that air flows from port "E" through the valve and out of the filter. Replace EGR SV valve if air does not pass through valve.

Checking EGR SV Valve Air Flow:

3. Using two J36169 fused jumpers, apply battery voltage across the terminals of the EGR SV Valve and blow air through port "E" making sure that air does NOT pass through valve and out of the filter. Replace EGR SV valve if air passes through valve.

4. Reinstall EGR SV valve. Refer to "Exhaust Gas Recirculation Solenoid Vacuum (EGR SV) Valve Replacement" in this section.
