A reading from my 2002 ford explorer said insufficient flow from the EGR valve. Would it be possible to clean the valve or fix it or would I need to buy a whole new valve?
Usually it is the manifold that gets plugged up with carbon impeding the flow of exhaust gases to the engine. Apply vacuum to the valve with the engine running, or lift the plunger off it's seat, the engine should stall. If not, remove the valve and see what you got. An old speedo cable and an electric drill is a great way to rout out the carbon, then blow it out with compressed air.
I have replaced several DPFE's for this reason. Never had to replace an EGR valve for the insufficient flow code. Like previously posted best to get a genuine Ford DPFE
It could be two things. The exhaust gasket coming to the valve or the vacuum coming to the valve. The egr did not need changing. Without the proper tool to check it out. I can not say which it is or how to repair. It need to go to shop where the proper test can be use to find what need to be repaired of replaced Most likely it will be a one way vacuum valve, that is not working right.
It probably has nothing to do with the actual EGR valve itself, there is a sensor called the PDFE, it monitors the flow of the egr valve, the flow is probably fine and the sensor that monitors it has gone bad, It is a VERY common issue on fords. I would start there. Good luck PS ford has an updated part number for the sensor so get it from the dealer
Could be dirty, or it could be the egr solenoid failing
