This is probably the single most frequently asked question pertaining to a vehicle, how to turn off the check engine light. Let’s first start with a little information. Did you know that you can get your check engine light scanned for free?
Any of the major parts stores in the country, such as: Napa, Advance Auto, Autozone, and O’Reilly’s, will scan your vehicle, and tell you the P codes for no charge at all. They will definitely try to sell you something, according to what the code is, but you’re not obligated to buy. Simply get the P code, come and visit us here, and get started with your diagnostics. 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, or cause you to think there is still a problem, because on very new vehicles, this won’t erase the check engine light at all. The safest, and best, way to turn off the light, is with a scanner. You can do the repairs yourself, and go back to the parts store to ask if they will turn it off for you as well. 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 it’s 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 anyone to scan your vehicle or turn off the check engine light
