I have a 98 Ford Escort 2.0. About a week ago I got a check engine light on and when I had the codes pulled I got P0401 p1131. I was promised by the parts guy at AutoZone that EGR one would be fixed by replacing the EGR valve, and he said it could even fix the 1131 code. So I figured I would trust him. ( I know I should have listened to Eric and never go souly on what the parts guy said)So I bought the part and put it on. While the part was off I did do a little cleaning in the actual port. I used some carb cleaner and then scraped the little amount of gunk that was there. I put everything back together and still had the codes. After doing a little research I found out that its more likely the sensor than the actual valve. So I was wondering where to go from here. Is there a good way to test the sensor. And The other thing I was wondering is could the two codes be related? I know the other code is referring to the Oxygen sensor after the CAT.
Just trying to get some advice on where to start or where to go from here. I have watched the videos that Eric has up for the P0401 Ford one. I was just trying to see what some of you guys think about it.

p0401 EGR insufficient flow. I know the valve
is new. check to see if vacuum is present to
open the valve.check the vac line itself for cracks.
P1131 thats your upstream o2 sensor.the one closest
to the engine not switching as it should.check for
vacuum leaks.How many miles on the car?Hi,
Have you watched this ScannerDanner one?
This video is for a 5.4L V8 but Fords EGR system is basically the same in all models.
or this videoYou will have to test the DPFE sensor for the EGR system like ScannerDanner does with a test-pin and apply pressure to one of the ports to get a voltmeter reading. If the DPFE sensor checks out OK you have to continue investigating why there is no EGR flow. As you have changed the EGR valve the logical course of action would be the EVR (EGR Valve regulator). I don’t know if the voltages are the same for a -98 Escort as the american Escort is not the same as the European one! You may have to look the voltages up! Good luck!
I’ve actually written and article on this very thing on this website, here’s a link.
