The code needs to be reset. The code you got was most likely "emission leak medium" this happens if the gas cap is left loose. If the code is reset, and you tightened your gas cap it should not come back. If it does, then get back with me and I can walk you through some steps and parts that will have to be checked, but I am 99% sure its only your gas cap, Happens to me all the time, and I just reset it after tightening my cap. Thanks.

Go to any of the Parts Retailers in your area and they will check the code for you and tell you what they believe the trouble is.

My check fuel cap light came on the other day after having been at the gas station. I later tightened the cap & the light remained on. Now several days later the check engine light has come on too,...


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.

Is it possible to rest the engine management light on a 2004 Dodge Dakota without visiting the dealers. I believe it has come on due to filling with premium grade gas. Thanks in advance.


Most auto parts stores offer free reading and resets of engine lights. Just call a local parts store and see is they have the capabilities and they will tell you what turned the light on. Premium gas should not cause a check engine light but not tightening the gas cap enough will.

Engine check light comes on and stays on for awhile then goes off. Dometimes when I fill the gas tank the check engine light comes on. is something to do with the gas cap or the instrument lights.


IF IT COME ON EVERY TIME YOU GET GAS.GAS CAP HAS BAD SEAL IT MORE LIKELY YOUR PROBLEM BUT LET AUTO ZONE SCAN IT FREE TO SEE WHAT TROUBLE CODE YOU ARE GETTING.

2002 Jeep Cherokee with 22,000 miles has check engine light on. What can this be so early in the mileage


Hi:
There are hundreds of things that turn on the check engine light, some are simple, like the gas cap loose, others are more complicated. A good thing to try is to stop by a local auto parts store, such as Auto zone, and most will scan your code for free and tell you what possibly caused the light. This way you can know for sure !

The 'service engine soon' light comes on repeatedly


I'm thinking the oxygen sensor is not working properly. Autozone or Advance Auto will do a check at not charge.
