Purge and EGR valves replaced but light comes back on.

[wh31966]

Hello, I have a 2010 Ford Explorer Sport Trac. The purge and EGR valves have both been replaced twice within 2 weeks by a car repair shop. I have it back at my home and am taking it to a certified Ford dealer service department next week to have them scan it. The check engine light came on this time after approximately 160 miles after having the second valves replaced.
I'm suspecting that it could be the ECU.
Has anyone else experienced this before?

Thanks!

Fuel tank EVAP/Pump connector corroded or the fuel pressure sensor clogged.

Check the EGR valve. Lots of bad new parts out there. I got a defective one from rock auto.

What is the actual code stored in PCM?
