Check engine stay all the time 2005 mercury mariner
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
