HI
without using the scan tool you can do it by disconnected the the battery for ( 24 h) to reset it or to ( 5 m) to reset the service engine light but the fault sty in the memory
WITH MY BEST WISHES

The light comes on when the car's computer detects that something has an incorrect reading that is sending that incorrect reading from the sensing unit to the computer.
Here's how i would attempt to solve it. To reset an service engine soon light take the positive terminal off of the battery and let it drain all the voltage and currents in your vehicle. Like try turning on your radio and turning your car over while the positive terminal is taken off of the battery terminal.
I would say let it sit for atleast 15 minutes then put it back on and start the car back up. If the light still comes back one then you have a small problem that could be many different little things
Check to see that your gas cap isn't worn out and still keeping a seal so when you take it off you should hear air escaping from it
Could be a filter in your fuel tank.
Could be o2 sensors
The list could go on, but to make sure before you start spending a huge amounts of money go to a shop and get them to plug in a scanner into your car to see what exactly the code is.
Good luck bud!

That's telling you your computer pick up a bad signal from one of your engine sensor's, have the codes read, go to any auto parts or autozone where they will do a free code reading, they can also reset the computer, but get back with us with the code number, so we can help you here at FixYa with your trouble code.

You can reset the light using an OBDII scanner. If you take the car to autozone and ask them to clear it out for you, they will do this at no charge using an OBDII scanner.
The other option that you have is to disconnect the battery for 5min. Leave it disconnected 5min , then reconnect. The check engine light will be reset.
Keep in mind that these will reset the light, if the fault/problem is still there the light may come back.
