Gasoline EGR valvesare very similar to high-pressure ones. The vacuum created by cylinder depression draws the exhaust gases in, and the flow is regulated by the opening and closing of the EGR valve. Vacuum-operated EGRvalves use a vacuum solenoid to vary the vacuum and direct it, opening a...
Use the scan tool to force the EGR valve on. If it responds, you may be facing an intermittent problem. For example, the EGR valve can become frozen if there is an excessive amount of moisture or the weather is cold. If you let the vehicle warm up, you may notice that the code can...
