That would be EGR. (Exhaust Gas Recirc). It is the diaphram valve that allows exhaust gases back into the intake to be reburned. Follow the small metal tube from your exhaust manifold(s) - they will lead to a flat, circular piece. that's the EGR valve. Some (not me) have had luck simply cleaning it - I always buy a new one. (not too expensive). But before you do that, make sure it's not just the vacuum line that is assigned to operate it. If that has a leak, it won't open either.

I had a service engine light on a nissan altima to come on autozone said it was a dirty erg and also had a po 400 code. what is a po400 code

P0400 is Exhuast Gas Recirculation Flow Malfunction or restriction.This would be carbon build up in the EGR Valve.You can take it off and clean it with a non-chlronated brake cleaner and wire brush or scraper.Other option is to buy a new one.

I am getting check engine codes that read EGR Flow CKT RNG/Perform and Engine Oil Pressure Switch CKT and EGR Closed Position/Perform

Replace what ever the codes say needs replaced,,,start with the ERG,,,Than run the scan again, if that engine oil switch comes up after you replace the ERG than replace it. Always clear the codes after you read them.

TCS and check engine light keeps coming on. We have had the code and it was the ERG value. We replaced and lights are still coming on.

You may have more than one code.
You may need a ABS sensor if the TCS light is coming on.
Check the codes again.

Air flow erg

could be MAF mass air flow sensor or your MAP sensor manifold absolute pressure. check for a cracked or worn hose going to the Map i had found a crack in mine one time. if its the MAF just see if you disconnect it and if the trouble stays the same then thats probably the problem..they should have been able to tell you what the code it said...was it calling out for? Some auto stores will lone this tool out as long as you hand them your drivers licence..but dont expect them all to do this.
