Exhaust gas recirculation (EGR) system - insufficient flow detected
Causes: Hose leak/blockage, basic setting not carried out (if applicable), wiring, EGR valve, EGR solenoid, ECM
Your EGR valve should be on top of the engine in the front between the intake manifold and the pulleys. It looks something like this:
First, make sure the vacuum hose is good and run it down to where it connects to the intake manifold to check for any leaks. If that's good and you want to get your hands dirty, take the valve off and see if it's clogged. clean it and see if you can actuate it with vacuum (put a vacuum hose on it, ****, and see if it will open. Also, look to see if there is gunk in the line and intake where it connects. Clean out anything you can with carb cleaner.
If you can get it unclogged and the valve is working, put the valve back on with a new gasket, else buy a new one ($40 at autozone :o( ). If you solve the issue, the engine light should clear after a couple hours of driving. OK?
