Most auto parts stores will read and reset the code free.How do i clear the codes for the check engine light?
I dont know anything about your car. Your check engine light can come on because you didnt change your oil. In your fuse box normally on the drivers side next to the steering wheel. You can reset it there (assuming its routine maintenence) Its possible its on the passegers side.





Normally you will start the car and press it 3 minutes, sometimes you have to do with with just the car engaged, but not turned on.





If you reset the button according to the manual, and the lite stays on. Its still finding an issue that isnt normal. Cars now will send that light on when you need to change tire, rotate tires, check the brakes, change your oil ect. Without knowing your car I cant tell you were to reset it. But I would assume its in the fuse box, inside the car on the drivers side. How to reset it will depend on your car.
Make sure you remove the NEG terminal of the battery. If not, the wrench will make huge sparks when it touches the frame or fender.





It will usually clear the light but if you have not replaced the bad wires it will come back.





If you can, get the code reader. You might only use it a few times but its so helpful that you'll use it on friends rides too.
The only way to clear service codes and turn off the check engine light on newer model vehicles is with a diagnostic scanner. i believe o riely auto part stores offer to do this for free. Plug wires should be replaced every 75 to 100'000 miles and should have no corrosion.
By all means, replace them.





You can pick up a OMD2 code reader for between $70 and $100 online, they usually have a way to clear the diagnostic codes from the computer.





If the light comes back on, get it checked out by a mechanic.
disconnect the battery, i don't know how long, but then reconnect it. if the light comes back on within a couple of days, then there is a reason and you need a code reader i believe but if you cant buy one, then i believe certain auto stores will let you rent one.
Yes you should replace the core. If you cant afford to go to a mechanic who can clear the check engine light sometimes if you disconnect the negative battery cable it will clear the light.
