Egr Valve Vacuum Hose Disconnected at Melva Patricia blog

Egr Valve Vacuum Hose Disconnected. The most common sign of a bad egr valve is a rough idle, a check engine light, detonation, and misfires. This could be caused by one of two possibilities, either the egr solenoid is defective or the vacuum hose is attached to the wrong port on the egr solenoid. An incorrectly operating egr can create smoke and excessive soot. The more subtle signs include increased fuel consumption, poor performance, and increased exhaust gas emissions. It’s a good idea to cover it with something to keep it from accidentally getting sprayed. Egr is for the sole purpose of reducing nox production. If it looks brittle or frayed, you might want to replace the vacuum hose as well. If you suspect that your egr valve is stuck open, the first thing you should do is check the engine’s vacuum hoses. So with the vacuum line disconnected (and the engine still running), recheck your reading on the dpfe sensor. Disconnect the wiring harness from the egr valve and pull it out of the way. Next, you’ll need to test the egr valve itself with a vacuum gauge to see if it’s stuck open and inspect it for carbon deposits. Carefully remove the rubber vacuum line from the egr valve.
