- Q:How is the EGR solenoid valve tested, and what differences exist for the 1996 Chevrolet C1500 based on GVW (Gross 1996 Chevrolet C1500 Weight)? Posted by Customer
- A:To test the EGR solenoid valve on vehicles under 8500 GVW, the ignition should be off, and vacuum applied. If it doesn't hold vacuum, replacement is required. For vehicles over 8500 GVW, the ignition should be on (engine not running) during the test. If the EGR valve moves, disconnecting the electrical connector and repeating the test is necessary. If the EGR valve moves, the solenoid valve should be replaced.Posted by GMPartsGiant Specialist
