2009 Mazda 5 check engine light after loose gas cap

Recently, my check engine light came on. After a bit of research I read to check if the gas cap is loose. After checking the gas cap. it was very loose. I tightened the cap as tight as possible (many clicks), and now I'm wondering if the check engine light will go off by itself or should I take it in to an auto repair shop? Could it be a different problem if the light does not go off?

If the code would have been due to the cap problem then the code will go away. Try resetting the code. Also try diagnosing again after disconnecting the battery and then reconnecting it after a few minutes.

Testimonial: "Thanks Daniel! I will try resetting and thanks for your time and the info!"

Keep it under 65mph!
Go to the nearest auto parts store and ask them to check it with a code reader. Advanced Auto Parts will usually do this for free!

SOURCE: have a 2007 mazda cx-7. 12000kms on it. check

Check the engine oil level. Let it idle and watch the oil light if it flickers or comes on then not safe to drive. Check while driving it does'nt overheat but this is very unlikely Otherwise you should have no problem. I don't know anything about Mazda problem's so cannot advise on that but engines in general are all the same.

It will not go off by itself,you will need to reset it by connecting to a diagnostic tool.Once cleared if there is any other problem then it will trigger the check engine light again.Hope this helps..

SOURCE: On my 2005 Mazda 6, my engine light is on and the

you would need a scan tool to reset it, if it is the gas cap and you fixed the problem with it then the light will go out after 100 miles of driving with a couple of cold starts. if it doesnt go out after a few days of driving then that wasnt the problem.

Testimonial: "Excellent feedback..I haven't driven 100 miles yet. I will continue to monitor my mileage..Thx"

Check engine light and AT light came on

First, double check that the gas cap is good and tight. Sounds silly, but sometimes a loose gas cap will cause the check engine light to come on. Failing that, take the car to someone who can read the codes. You might have a bad or lazy O2 sensor but the codes are the quickest way to tell.

Reset Mazda 5 engine light

Your engine light is on because something is out of parameters, ignoring it isn't wise. If you need to reset, often disconnecting the battery for a minute or two will do the trick, otherwise go to a nationwide automotive retailer and they will lend you the OBD tool to connect and delete the fault code. If the problem isn't fixed tho, the light will come back on soon thereafter

Mazda tribute problems

The indicator is actually telling you there is a leak in the evap system. This can be caused by a loose cap, on cars that have them; but it will come on for any leak in the system. The capless fuel pipe may not be sealing, or any hose in the system may be leaking. Check the small hoses connected to the engine intake manifold--one of those is the purge line, which is part of the evap system. The rest of the system includes a charcoal canister and a vent line from the fuel tank. There may also be a vent valve connected to the canister. A leak in any of these can cause the light to stay on and may affect the operation of the engine, if the leak is large.

Check engine light & Slip indicator light on together why?

Both the Check Engine light and the Slip Indicator light on my 2009 Tacoma came on for no apparent reason. The truck has only 34,000 miles on it. After reading blogs on the internet by people having the same problem with their Tacoma, I tried the easiest potential fix first: just tighten the gas cap until it "clicks" and disconnect the positive cable from the battery for about 20 minutes. Bingo, that fixed the problem! Those simple actions saved me a trip to the Toyota dealer and who knows how much in charges by their service department.

2006 Saturn Relay Check Engine Light

PO455 is a large evaporative fuel leak. A bad fuel cap is ONE of the things that COULD be the problem. Fuel system cleaning only lightened your wallet. Reading your post is confusing. Did all this start AFTER the Valvoline Wallet Flushing? If so , they left something loose or disconnected. I would find a qualified repair shop to fix the problem, and if it has anything to do with what Valvoline did, make them pay the bill.

Check engine light came on this morning, mazda 3 09', it has 14,500 miles, i just got an oil change at the dealership a few days ago, also i think the gas cap was a little bit loose i noticed the last time...

I would take it back to the dealer and tell them the check engine light came on not long after oil change. Have them run the code on their dime...it's a reasonable request!

A loose gas cap will defintely trigger the engine light, but in most cases, it will reset itself within one week. Some cars don't have a reset which forces you to have a mechanic reset it for you.
