Check engine. Light

The check engine light is commonly activated by a loose gas cap, regardless of vehicle make or model. Having said that, it could also be a more significant issue. You may want to err on the side of caution and schedule a maintenance.

If it's come on recently (especially if you noticed it shortly after refueling) and you don't notice any difference in the way the vehicle has been starting, handling, or otherwise operating, you can try to unscrew the gas cap, screw it back on based on the vehicle user manual or instructions printed directly on the cap (i.e. turn until three clicks, turn until hand tight), and drive the vehicle around for a few days. The light usually won't deactivate immediately after correcting the problem. You'll have to drive it around for a couple of days to a week in order for the check engine light to go away.

Ran out of gas recently. when refueled and started again,check engine symbol stayed on? well mainted and has always ran great since new.

Sometimes the check engine light will come on if the fuel cap is not on tight enough. Check the fuel cap for an intact seal and install at correct tightness.

A major auto parts store will read out the stored trouble code in the car's computer for free. If the code pertains to the fuel EVAP system, the code probably set because you ran out of gas. Copy down the code and then have it erased. The check engine light should go out. If it comes on again, have the code read and the problem checked out.

Gas cap light on my 2007 explorer xlt is on and now the check engine light is on how do I get them off.

Check to see if the cap seal is good and the cap is tight. Next I have to ask if some one is refueling the vehicle while it is running like in cold weather to keep it warm. The system will see the gas cap off at that time and turn the lights on. If all that is good have the codes run to see what it is. Just about any parts house can do that for you and they might be able to reset the system. If the lights come back on then you have a problem that might have to go to a shop to be smoke checked for a leak.

2002 kia rio rxv check engine light came on again..

the check engine light is not caused by any wrong fluid level or dirty air filter or anything else like that, it is caused by well over 100 faults that can occur in the computer controlled electronic engine and emission controls, u will need to go to a Kragen or Autozone parts store and get a free OBD 2 fault code test to get the code that set your light.
