How to Reset Check Engine Light Without Disconnecting Battery?

When the computer in your car finds a problem with the engine or emissions system, the check engine light comes on. The check engine light could be on for a number of reasons, such as a loose gas cap, a broken oxygen sensor, or a problem with the catalytic converter.

The check engine light means that something is wrong with your car. You should take it to a skilled mechanic right away. But there are some things you can do on your own to see if they clear the check engine light.

  • Method 1: Using the ignition key

The steps in this method are easy to understand. All you need is your car’s ignition key.

  1. Do not start the engine when you turn the ignition key to the “on” position.
  2. Wait for ten seconds.
  3. Press the “off” button on the ignition key.
  4. Do steps 1 to 3 three times.
  5. Check to see if the check engine light is off after you start the car.
  • Method 2: Using an OBD-II Scanner

An OBD-II reader is a tool that can help you figure out what’s wrong with your car’s engine. You can easily purchase an OBD-II scanner online or at most stores that sell car parts.

  1. Attach the OBD-II reader to the port under the steering wheel of your car.
  2. Do not start the engine when you turn the ignition key to the “on” position.
  3. The OBD-II reader will tell you how to clear the trouble codes.
  4. Check to see if the check engine light is off after you start the car.
  • Method 3: Reset the Check Engine Light with a Push Button Start

If your car has a push-button start, do these things to clear the check engine light:

  1. Turn off the engine.
  2. Put your foot on the brake pedal.
  3. Hold down the start button for 10 to 15 seconds, or until the check engine light goes off.
  4. Release the brake pedal.
  5. Start the engine for the vehicle.
  • Method 4: How to Reset Check Engine Light Without Scanner

  1. Don’t start the engine after turning the ignition to the “on” position.
  2. Just wait a second or two.
  3. The “off” setting should be selected in the ignition.
  4. Do steps 1 through 3 three times.
  5. Start the engine for the fourth time.
  • Method 5: Remove the Check Light Fuse

  1. To turn off the check engine light by taking out the fuse, you will need to:
  2. The owner’s manual for your car will tell you where the fuse box is.
  3. Find the check engine light fuse in the fuse box. The fuse’s name is usually “CEL” or “Check Engine Light.”
  4. To take out the fuse, use a fuse puller.
  5. Put the fuse back in after 10 to 15 seconds.
  6. Start the car. There shouldn’t be a check engine light on.

Here are some ways to find the fuse for the check engine light:

  • Most of the time, the fuse box is under the hood of the car, close to the battery.
  • A black plastic lid usually goes over the fuse box.
  • There is usually a diagram of the fuses on the lid of the fuse box. This will help you find the check engine light fuse.

Warning: Removing the check engine light fuse may prevent you from passing an emissions test.

Please keep in mind that taking out the fuse for the check engine light won’t fix the real problem. If your car is having trouble, you should take it to a qualified mechanic to find out what’s wrong and fix it.

  • Method 6: Use the Gas Pedal to Turn Off the Check Engine Light

One way to reset the check engine light in older cars that don’t have improved onboard diagnostics (OBD-II) systems is to press the gas pedal. Don’t forget that this method might not work for all cars, especially new ones. Here’s how to use the gas pedal to try to reset the check engine light:

Please keep in mind that this way isn’t perfect and won’t fix the real problem that’s making the check engine light come on. It’s more like a short restart or dimming of the light.

  1. First, turn off your car. Make sure the car has been sitting for a minute or two and the key is not in the ignition.
  2. Find the gas button. It’s most often on the right side of the footwell on the driver’s side. Remember to take your foot off the gas.
  3. Hold down the gas button. Do not put the key in the ignition. Instead, press and hold the gas pedal to the floor. Put it all the way down and hold it there.
  4. Put the key in and turn it. Press down on the gas pedal and then put the key back into the ignition. Turn the key to the “On” position. Just turn the key until the dashboard lights come on. You don’t have to start the car.
  5. Hold on until the light goes out. Hold down the gas pedal and keep an eye on the check engine light on the dash. It should either start flashing or turn off in the end. It might take a second or a minute to do this.
  6. Let go of the gas pedal. Let go of the gas pedal when the check engine light stops flashing or turns off.
  7. Turn off the ignition. Return the key to the “Off” position and take it out of the ignition.
  8.  Give it a moment. Put your car in “Off” mode and wait a minute or two to make sure the reset works.
  9. Turn on your car. Once the time is up, start your car properly and see if the check engine light stays off.

Note: You should know that this is only a short-term fix. You should get your car checked out by an experienced mechanic to find out what’s wrong and fix it.

To keep things simple, this method erases the trouble codes saved in the car’s computer. This might temporarily turn off the check engine light. But it won’t fix the real problem that made the light come on in the first place. If the problem doesn’t go away, the light will probably come back on, telling you that you need to have a tech look at it and fix it.

Simple Trick to Turn Off Check Engine Light

Don’t worry if you see a check engine light on your dashboard. You can try a simple trick with just your gas pedal to turn it off.

There is a small chance that this trick will work if the check engine light is on because of something like a loose gas cap or a broken oxygen sensor. If the light is on because of a bigger issue, like an engine that isn’t firing right or a broken catalytic converter, this fix won’t help.

Stick your foot on the gas to turn off the check engine light:

  1. Do not use your car at all.
  2. Step on the gas and hold it there.
  3. Press the “On” button on the key, but don’t start the engine.
  4. Hold down the gas pedal for 10 to 15 seconds.
  5. Turn the key to the “Off” position and let go of the gas pedal.
  6. Please wait a moment or two.
  7. As always, start your car.

Do the steps above again if the check engine light is still on. If the light stays on after a few tries, you should take your car to a mechanic to find out what’s wrong and fix it.

Keep in mind that this trick will only get rid of the trouble codes in the car’s computer. The problem that made the light come on in the first place will still be there. The light will likely come back on if the problem doesn’t go away. If you see a check engine light, it’s always best to have a qualified mechanic look at your car.

Why does this trick work?

When the key is in the “On” position, the computer in the car does a set of tests on its own. It will read the trouble codes and turn on the check engine light if it finds any problems.

The car’s computer will erase the trouble codes if you press and hold the gas pedal to the floor while turning the key to the “On” position. For this reason, pressing down on the gas pedal tells the computer to clear the codes.

Keep in mind, though, that this trick will only work for a short time. If you don’t fix the problem that made the light come on in the first place, it will probably come back on. If you see a check engine light, it’s always best to have a qualified mechanic look at your car.
