How to RESET check engine light
What’s up guys because you can’t attack now I’m going to show you three easy ways to reset your check engine light last way I’m going to show you is the best way I highly recommend it but it cost you I think around nine dollars.
I’ll leave a link in the video description below alright the first thing you do is put on your gloves you’re going to be working on the battery when I discover the positive terminal and the negative positive has the red cap the negative has the black cap.
I’m going to get your socket wrench and unscrew the nut counterclockwise and then wiggle off that black connection that negative connection you want to hold off for about 30 to 60 seconds that should clear the check engine code now if it doesn’t then you want to try the second method second method is easy put that negative to the side make sure it’s not touching the battery press and holds a horn that’s going to release some of the stored energy in the car circuit board.
You could turn on your headlights that’ll also release some of the stored energy in your car circuit now if that doesn’t work then we could do is remove the positive terminal from the battery to connect the jumper from the disconnected negative terminal and the disconnected positive and hold that jumper on it for about two seconds and now would also release in the stored energy and I don’t really recommend these message.
I highly recommend the next method make sure you put everything back together after that jumper and warning this will reset your car radio are the best way to check your check engine codes and to reset them is using the obd2 diagnostic tool plugged into your obd2 port on your car.
Most cars have it the works with the torque app on Google Play Store or the Apple Store works I think that without the source here as well they have their own version and only if you have to do is plug it directly here you can leave it plugged in it doesn’t kill the battery at all I left it plugged in for weeks on end and never killed my battery but uh only thing you have to do is just have the extension and I leave it plugged in and you just plug that extension in right here just plug it into the extension and then I have velcro it right here on the side just like that.
And it connect via bluetooth to your phone and there’s actually real time monitor turn so what you want to do is turn on your car right here as you can see turns on the car we have the check engine light right there you want to go into your app click on fault codes and have here he’ll get in the car and it tells you right here so most car scanners will tell you the code it will be P 102 but this actually tells you P 102 and actually tells you mass or volume air flow circuit low input alright and it does right here as well so let’s go ahead and go to my car.
Under my hood so of course there’s something wrong with it it’s unplugged because I unplugged it to simulate the check engine light and so what we’re going to do make sure the cars turned off when you do this what you do is just plug it in lock it in oh whatever problem you have it could be a loose gas cap that could be it maybe if you got them tighten your gas cap when you’re off the gas station that could actually trigger a check engine code which is common if that’s the case just go to your car and make sure your gas cap is on okay so once you get back in your car you want to make sure this is all plugged in there’s power going to it and it’s communicating to your computer and let’s try it again and you want to turn on the app of course and turn your car back on all right so we still get the check engine code even though we fix the issue
And then you want to go back into your so what you want to do now is you want to go back so you want to do is go back into your fault codes right here and here’s all my fault codes and so this is actually just a record it’s not currently a fault because we actually plugged it back in.
I’m going to click on the menu button right here on the upper right and then clear fault codes and then click OK and then as you can see look at the just it disappeared as soon as we did that and it says completed that’s how you do it now of course if you didn’t fix the problem that you know the check engine light will come back on but you know if you know if there was a loose gas cap and you tighten your gas cap it shouldn’t come back on and this is real-time monitoring just to show you let me read my engine okay pretty cool stuff.
So I highly recommend this device it’s about eight or nine dollars and Amazon I’ll leave a link in the video description below where to get it so if this video was informative give me a big thumbs up if you want more how-to videos coming your way subscribe to Tampa tech click on this link right here and if you want to check out my car how-to playlist click on this link right here and share this video to anyone this video may help thanks guys for watching.
