Honda Accord EGR Valve
Testing Ported EGR Valve
1. Run engine to operating temperature and allow it to idle. Attach a vacuum gauge to EGR vacuum hose. Locate EGR vacuum solenoid.
2. Using a jumper wire, ground signal wire from ECM to EGR vacuum solenoid. Vacuum should be present at EGR vacuum hose. On some models, engine speed may have to be increased 3000-4000 RPM.
3. Connect a vacuum pump to EGR valve. Start engine. Apply vacuum to EGR valve. If engine runs rough or stalls, and gauge holds vacuum, EGR valve is functioning properly.
