You will have to have it reset with a scan tool. Disconnecting the battery won't do it anymore. Go over to a parts store that has a scan tool and ask them to scan it for you and tell them to clear the code. It probably set a fuel evaporative leak large code.

    If you are in the Austin TX area I would be more than happy to scan and reset it for you for free. If my reply helped please give it a rating.

Where is the ecm fuse located on 2004 grand am gt


If the light is still on with the engine running, the problem has not been resolved. The computer is still seeing the problem. Had the gas cap fixed it, it would have turned off the light and kept the trouble code stored in memory.
You can turn the light off and erase the stored codes, but it will likely return. The approved method is to use a hand held scanner, a free service at autozone and a few other national parts stores. Before you have them erase the codes, write the number down and post it here. Maybe someone can help you find the problem. Those diagnostic trouble codes are all over the internet-you can google it, or you could find a site that is devoted to them. Here is one, a good one that gives the description. If you click on a particular code, you can go to a page with some discussion about possible causes and solutions:

Engine light on


Your engine light can come on for about a million reasons. Its best to go to a part store most have computers and some will hook up your car at no charge and tell you the code its showing.

sometimes this can be simply you didn't tighten your gas cap all the way. Remove your gas cap, then put it back on and be sure it clicks 3 times. The engine light will not go out right away, it takes a few trips out, around 3-4, hope this is helpful. Good luck

I get a po455 code on my 2004 grand prix


I had a check engine light on for my gas cap. I fueled up and sometimes it would say "check gas cap" So i just plugged it in under the steering wheel and cleared the check engine light from my dash board. So far so good.

2004 pontiac grand am service engine soon light


I have the same car and if the gas cap is loos for any reason the service engine light will come on so check that. If it is it will turn off in a few days after you tighten it.

Service engine soon


hi, this is just a reset issue. sometimes the CPU can become confused. the original warning that informed you about your gas cap is still in the cpu's memory. you will have to reset the cpu and, this will clear the warning. After the reset, it will stay off. chevy cpu's tend to do this from time to time.

Service engine soon light 2004 Alero


if it truly set code for "loose fuel cap" or po455 large leak, then tightening the cap and driving a couple days should reset on its own. if not then get it checked for free at autozone and report back with code # and can help from there. they'll ck for free but are not allowed to reset.
