In Texas, for the annual state auto inspection, now they check the computer codes if they see the Engine Check bit set on the computer. Mine was set but I guess my light was reset or something because I never saw it on since the time I bought the car used. Anyway, it was set because the computer says my EGR sensor is low and my EGR tubing is clogged. I replaced the EGR valve and the tube turned out to be very clean inside. The repair man said I had to drive through many different driving conditions and scenarios to be recorded before the error codes would clear. I have driven very much since but the codes are not clearing. Does the O2 sensor have to be replaced or something like that even though I didn't get an error for the O2 sensor? One of the conditions is that I have to drive when the outside air temperature is over 70F. Is there maybe an outside air sensor that could be out? What usually stops the EGR codes from clearing? Is it a problem with the computers software and is there a software update that fixes the computers' inability to ever clear the error? Thanks if you can help, George
