How long does it take for a new PCM to open?
A brand new valve takes only about 50 milliseconds to open but an older valve may take up to 350 milliseconds or longer – which is not long enough to cause a real NOx emissions failure but is long enough to trip a fault code. The fix in this instance is to reflash the PCM with new instructions that allow more time for the EGR valve to respond.
