egr blues!

I have a 2002 ford mustang and have had my service engine light on for a while. I decided t take in to auto zone and they diagnozed it as egr - insufficient flow. I took the valve out, clean it....reset the didn't work...I brought a new egr valve, installed it, reset the computer...the engine light came back on again within 1 day......any further suggestions on what I could try?

Thanks in advance for any help.

Re: egr blues!

When you bought the new EGR valve, did it come with a new EVP (EGR Valve Position) sensor. It is screwed onto the end of the EGR valve. It provides a signal indicating valve position to the ECU. If you are still using the old EVP, it may be at fault.

The other item to look at is the EVR (EGR Vacuum Regulator). It controls how much vacuum is ported to the EGR valve. It may be faulty. To locate this, just follow the vacuum hose from the EGR valve, it leads straight to it.

Needless to say, with these items using vacuum as a motive force, check your vacuum hoses for this system. Any leaks will affect the system. If vacuum is low, so will be EGR flow.
