Automatic Transmission Control Module problems of the 2006 Chevrolet Equinox

I replaced the egr valve sensor and hose still getting a code 1404. I don't understand what the main problem could be unless it's the pcm causing problems and it has been changed as well.

Vehicle will not pass state required emission, due to readiness error code. For reasons unknown the evap and egr system code will not reset (not ready code). We were told by several mechanics to drive the vehicle for several hundred miles. After 800 miles and several failed test later the system still will not reset. We called gm and was told to take the car to a dealer. Against our better judgement we had no other options available and finally took it to our local gm dealer and was told the service tech downloaded software to address a p0171 code, which cost us over $300 and to drive it 200 more miles, bring it back for a test. The system still did not reset and the car will not pass emissions. We asked the service manager for other options and all he could give us was lip service (useless rambling), possible troubleshooting repairs and more money. I found on a topix website that gm recalled the pcm for the Equinox but could not find the recall on the NHTSA website. Please research and post the recall if gm has issued one for the pcm.

I have a 2006 chevy Equinox and I've been having difficulty starting it. The cd/radio was not working correctly displaying numbers/letters and signs. -failure to start -poor fuel economy -radio/cd failure I did some research and found that the 2005 chevy Equinox had the same problems and a recall was issued for faulty pcm, which was covered under a NHTSA recall for replacement. The report indicated that it can cause the problems listed above at random times: I checked with the dealership and they indicated that there is no listing for recalls on my 2006 chevy Equinox.
