Check Engine Lights - Free Check

1. DO NOT drive at high speed!

2. Take this vehicle directly to O'reilly's Auto parts, Autozone, Advance Auto,.. they will diagnose the problem through the computer!!

You need to stop at one of the part stores that offers to read the code for free and will tell you what the code means. Auto Zone, Advance Auto are two I know of, Pep Boys in some locations will as well.

Ok,you could have a bad fuel cap or o-ring on the cap. could be you just didn't quite get the cap on good enough the last time you got gas so in turn the light comes on. unfortunately these things are so sensitive that the light doesn't go out even though you have tried taking it off and putting it back on. My advise is, check out your local auto parts stores. such as Autozone, or Advance. Most auto parts stores anymore will hook up a small scanner to your car and can tell you what the problem may be. not as good as a dealers repair shop could tell you,but should be able to let you know if it is nothing serious or could be. if it is something serious then you would of course have to see mechanical help. and if its nothing serious, like the only thing showing up is gas cap not on good,they can clear out the code and your light will go off and your good to go.if it turns out that's all it was and the code is cleared, and it keeps coming on, you could have a more serious problem and should have a qualified mechanic check it out. if you don't have an Autozone or Advance near you, just check your local auto parts stores and see if they offer the service of checking your vehicle when lights like this come on. and it should be a FREE service. Autozone and Advance is and most should be. i know this is long, but i hope it helps.

A good place to start is to see what codes are stored on the computer using an obd-II scanner. Many engine and transmission codes are possible, so this will narrow down the possibilities from several hundred down to a few possible problems with the vehicle.

Try autozone or advance auto parts to see if they will scan it for free.

I don't know that they would be related.  Do me a favor and take your car to an auto parts store (AutoZone, Napa, Advance Auto Parts) and have them check what the error code is.  They do this for free in TN.  Take that code and you can post back on here what it is and someone can help you with that.  Sorry, that's the best I can offer on that.
