    Can my car pass emissions with an engine light?

    My car has been running fine (1999 Nissan Maxima) but the engine light has been on forever. The code is an ignition coil but I replaced them and it is still on. Can I pass emissions in CT with a check engine light if everything else is alright?

    Thanks!

    I doubt it. Most states no.
    Go to autozone and get a hand held scanner and clear it yourself.
    Since it isn't emissions related, they should let you do it.
    Sometimes they won't let you clear ses lights. Depends on the state I think.

    you can clear the light, but then you'll need to do another drive cycle to activate all the sensors and get rid of the p1000 codes.

    On OBD-I, I have seen them pass a light truck w/ the CEL on. But your '99 is OBD-II, so I doubt it.

    Unplug the battery for a while. Then plug it back in and it should have cleared the code.

    Did you clear the code after the coil replacement? If not clear it and do a drive cycle to reset the readyness monitors. If the code doesn't reset, your golden.

    Nope. They check to see if the light comes on before starting the car. Plus, they'll see the tape

    It'll still show OBDII should snag the code. If you fixed the problem and the code is still popping.... is it something else?? It's worth a shot, but I doubt they'd pass you.

    They passed a law a couple years ago in NY that all OBD-II and 1996-present model year cars need to have a clear code scan to pass.

    Depending on what the code is for it can take a couple cycles of the ignition for it to come back. Pulling the battery cable will clear the history also.

    Or, if they are stupid and look for the SES light just cut the wire for the ses light. Not that I would recommend or do this.

    Yeah, I can't figure out what it is. But something is not agreeing because when I reset the light it still comes right back on. Car is running fine though--no misses etc. Strange.

    What kind of car and what was the code? Maybe we can help.
