Very well could be a small evap leak.Did you get gas earlier that day?Check and make sure your fuel cap is tight.
Take it off and spin on till it clicks 3 or 4 times.
Drive around for a day or two and the code should clear.
If not,take it to a mechanic and just have them pull the code.
I believe most autozones will read the code for you as well.
That should lead you in the right direction.

Check engine stay all the time 2005 mercury mariner


Hello,

There is a lot of things that cause a engine lite to stay on.

Here is just a few things, that will have engine light stay on:

Service is due, some cars have that automatically do this when time for regular service.

Breaks, Some cars have a sensor that after a certain range on your pads, it triggers the service Light.

Oil Low, or water/antifreeze low.

Emission problem, Like fuel filter needs replacing or possible 02 sensor not working ( part of your Cadillac converter)

Battery not fulling charging, or alternator not putting out proper amps. etc,,

This list can go on and on, most the time if you have low oil, or break issue, there is separate warning lights for that.


Here is what I think, sometimes when you have something wrong with your car, if you checked your oil level, water/antifreeze level, breaks seem good, and all your other fluids are good, and your car is running good and as normal, what best to do, is take it in and have them put it on there computer, this will tell you if there is something your over looking, by normally a code that comes up on there system. Sometimes the code will come up on there computer and not on your dash warning lights. Auto Zone, normally can do this for free with there hand held computer and tell you what comes up and what to check out. And all Garages if everything is ok, can with computer turn your engine light off if everything is ok. But for sure get it checked, and don't just assume it is a faulty engine light coming on, most the time there is a reason. Thanks Mike

Check engine light is on. don't have an owners manuel


There are many reasons for a check engine light to come on. If you are near a large auto parts store they will ususally hook it up to a computer and tell you what code is setting off the check engine light. The most common cause for a check engine light is a vacuum leak. This will usually show as an "engine lean" code. Meaning your engine is getting too much air in comparison to the normal amount of fuel. However, bad catalytic converter, faulty oxygen sensors, faulty exhaust gas recirculator, faulty positive crankcase ventilation valve could all be bad. It is too expensive to just replace everything, so getting the correct code from Autozone or Advance auto parts is important.
