Replaced battery now the car will not put out any codes to pass inspection
Hi there,
I'm assuming you are referring to your vehicle's on-board diagnostic codes?????
When replacing the battery (i.e. disconnecting power from the vehicle), this will RESET your vehicle's OBD computer.
When the computer is reset, NO CODES should be present, UNLESS the computer has detected a fault.

I'm assuming that it is a four cyl.The p0401 code is for insufficient egr flow.Most of the time it is the egr vsv valve (vsv means vacuum switching valve)which is what controls the vacuum to the egr valve to open it.It is kind of hard to get to as it is on the block under the head on the back side.If you follow the hose from the egr valve it goes to the vsv.I have also seen mice eat holes in the vacuum line which would also give you problems.I hope this help and let me know if you have anymore questions

HAVE YOU REPLACED THAT PLUG AND PLUG WIRE,FIND NO3 CYLINDER AND PULL THAT WIRE OFF SEE IF ILDE OF ENGINE CHANGES IF NO THEN YOU MAY HAVE BIGGER PROBLEM BUT DEFINITELY CHECK FOR SPARK WITH WIRE ON PLUG ITSELF.
SOURCE: can't pass state inspection, changed EGR valve already, next?
I suggest quit hunting for maybes and rent an OBD code reader which ends up being free when you return it to the auto parts store. Connect it and find out what is causing the CEL condition. Normal issues are the O2 sensor, or sensors in the system.

If the "evap not ready" readiness monitor never clears and you keep getting P0440,P0441,P0446 type codes, then you have a problem with the evap system. You have already tried the gas cap (good start) but there are about 6 other things it can be from electrical VSV air valves (there are 3 of them, 2 under the hood, 1 near the charcoal cannister (behind fuel tank) to 2 air operated valves on the front of the same cannister. There is also an air line that goes to one of the electric VSV valves on the air cleaner under the hood. Several oil change places have been guilty of pullling these off and not reconnecting them.
