Default engine light on again

[QUOTE=whh;44138]I'm new to the forum, looking for some help.
Engine light problem, nissan service serviced and replaced evap purge valve. Next day light was on again. This time, code 1490/1491, vacuum cut valve and bypass cut valve solenoid. My wallet was empty, so I passed on paying nissan another $500 to fix.
Now, I need to get the car inspected by DMV, so it needs to be fixed. I investigated the repair, saw that it was not difficult, purchased the parts from the dealer and replaced. Cleaned out broken plastic pieces from cut valve and so forth. Everything went together well.
The bad news is the light is still on. That brings my question, does the cpu need to be reset? Will it auto-reset if given time? I disconnected the battery for a short time, which did nothing.
Any advise what to do next?

Now, after three days of no engine light on bliss, it is back on. Went to my local Auto-Zone to find out what code comes up.
The new code is 1456. What do I do now? I already looked at the gas cap, which when opened released pressure, which looks ok.

Please advise, it's got to go through emissions by the end of the month.
Bill
