So How do You Turn Off Your Check Engine Light?

On older vehicles you could just disconnect the battery, wait for 5 minutes, and reconnect the battery. The light would be out, and you would be good to go. However this can mask a problem that wasn't fixed, cause your radio not to work. On very new vehicles, this won’t erase the check engine light at all causing you to think there is still a problem. The safest, and best, way to turn off the light, is with a scanner.

Here's a tip that a lot of people don't know: if the problem that caused the light is fixed, the light will eventually go off by itself. It can take a week or more, but if the problem is truly fixed, it will absolutely go off on its own. Nobody really wants to wait that long to find out if the repair they've done is correct or not though. So, with a hand held scanner, or a blue tooth scanner for your smart phone, you can erase the light yourself, and avoid paying a mechanic to just to scan your vehicle or turn off the check engine light.
