Why Is mine "Check Engine" irradiate On?

You've solved the problem that made her "check engine" light turn on, but now that won't revolve off! This may not be her fault. Sometimes the computer in your car will require a tiny help to check out that the concern has been resolved. I'll go over a few techniques because that resetting your check engine light.

This light screens itself as soon as the onboard computer system recognizes an electrical or mechanical trouble with her vehicle. Once the problem is fixed, the engine irradiate does not always turn off. This can be annoying, cause you to fail an emissions (smog) test, or keep you native finding out about future troubles the vehicle's computer might be trying to alert girlfriend to.

Of course, it is vital to be sure that the light isn't on since your engine yes, really does still have a problem. Shot one (or more) the the complying with approaches to revolve the light off. If the does no go off, then your engine has a problem.

MethodTools Required

1. Drive her car and also let light go off through itself.


2. Revolve the engine on and off 3 times in a row.


3. Disconnect and also reconnect the battery.


4. Usage an OBD password reader.

Wrench and OBD reader

1. Drive her Car and also Let the Light go Off through Itself

The first and easiest an approach for clearing the examine engine light is driving and also time. Most onboard computers will recheck whatever trouble caused the inspect engine irradiate to activate many times. Drive your auto as you generally would.

If the inspect engine irradiate is still on after three days, your problem may not have actually been solved or you might need to try some of the methods listed below to reset it.

2. Revolve the automobile On and also Off three Times

Some vehicles will instantly reset the problem codes that brought about the initial error after ~ the auto is turned on and also off 3 times in succession. To execute this, insert your crucial into the ignition, turn the automobile on for about a second, and then turn off for about a second. Repeat this two more times then drive the auto as normal. Check to watch if the examine engine irradiate reset.

3. Disconnect and also Reconnect the Battery

You will require a wrench. Prop open the hood and also use the wrench to disconnect the hopeful power cable to the car battery. Leave the battery disconnected because that at the very least 15 minutes. Then put your vital into the ignition and turn it 3 times come the “ON” position. This will certainly clear the emissions data indigenous the car memory as well as the readiness flag data.

Reconnect the hopeful battery cable and also turn the crucial in the automobile ignition. Wait one minute and also the examine engine irradiate error should be gone.

4. Use an OBD password Reader

You will require a wrench and an OBD (onboard diagnostic) reader. These inexpensive readers analyze and also clear engine codes. I have actually used the Kobra OBD scanner with an excellent success many times because that this task.

To execute this method:

Plug the reader right into the OBD harbor of your vehicle. This harbor is usually located on the underside the the dash area just over the foot well. On some vehicles, you'll need to remove the door on her fuse box to access this port.Once girlfriend have connected the reader, press the "enter" switch to turn it on.The an equipment will scan her engine for any error codes. As soon as done analyzing, the reader will display any error password it finds. Make note of the password (if any) if you wish to cross check them in the code reader's hands-on or online.Now you can press the "scroll" button to uncover the option to erase the code. Press get in while ~ above this choice to erase the fault code and reset the check engine light.


Frequently request Questions

Here are simply a handful of frequently asked questions related to this issue.

Can the check engine light turn off by itself?

Yes, sometimes the light will turn off by itself together you journey it approximately for a while after ~ addressing the worry that make it turn on in the an initial place.

Why walk my check engine light turn on and off intermittently?

There might be a few reasons why this is happening. A loosened gas cap, failing engine sensors, bad spark plugs, faulty valves such together in the EGR (exhaust gas recirculation) system, or intermittent misfiring could all it is in potential culprits. In this case, it's often best to take it your automobile into a mechanic shop to acquire a diagnostic, or in ~ the really least use an OBD leader yourself.

Does the examine engine light revolve off immediately after repair?

Sometimes yes and other time no. If the problem has to be repaired and the computer has to be cleared with a scan device or code reader, climate the light show turn off reasonably soon after.

That's not always the case though, and the light might still continue to be on (or turn on and also off intermittently)—especially if you have actually a larger electric or wiring problem.

If you acquired your automobile repaired in ~ a mechanic shop and also the problem seems to be resolved yet the light stays on, however, climate you have to take it ago to the shop and ask the mechanic if they deserve to reset the light.

Do I require a special tool to revolve off my examine engine light?

Yes. If you want to turn off your examine engine irradiate yourself, climate you will need an OBD password reader. That plugs right into the diagnostic port commonly located under the dashboard in cars made in 1996 or after. These tools can be purchased at various automotive parts stores or virtual at various retailers such as Amazon.

Be advised, however, the if you use an OBD leader to clear the code however the worry has not actually been resolved, climate the check engine light will likely turn back on again sometime quickly thereafter.

These methods Should assist You Reset Your examine Engine Light

Following these approaches will enable you come rid the annoying inspect engine light also as permit for new problems to be presented properly.

Whether you pick to manually reset the onboard computer by resetting the battery or by making use of an OBD reader, you will be able to successfully deal with the error. You might use these methods to fix the check engine light error as well as any other errors in the future should they existing themselves.

This post is accurate and also true to the ideal of the author’s knowledge. Contents is because that informational or entertainment purposes only and does not substitute for an individual counsel or professional advice in business, financial, legal, or technical matters.

Questions & Answers

Question: deserve to I get rid of the "check engine" light without an onboard diagnostic reader?

Answer: You certainly can, yet it may be much more difficult. Ns would start by make the efforts the other approaches outlined in this article. If those don't work, climate there is most likely something mechanically wrong with the vehicle.

It have the right to be as simple as replacing basic to reach $10 sensor that has actually gone bad, or much much more difficult. While some professional mechanics deserve to troubleshoot your vehicle and locate the worry without the help of one OBD reader, most civilization (such as myself) require a password reader to make things less complicated for us.

A code reader can assist you through manually permitting you to clean the fault code that has actually caused the check engine irradiate to illuminate (in situation it to be stuck on because of an error in the car's computer), or if over there truly is miscellaneous mechanically wrong then it can offer you the "error code" that your car is producing.

This error password is the actual reason the examine engine light has actually been activated. You have the right to then look up this error password in the reader's hand-operated or online and also see what the problem is v your vehicle in plain English. That is a handy tool that even most expert mechanics quite greatly rely on these days.

Question: Why walk my inspect engine light come on ~ I changed some fuses?

Answer: likely one that these situations occurred:

1. You changed a fuse v a fuse of an not correct value. Twin check that you provided the correct type of fuse per the vehicle's manual.

2. Among the fuses you put is bad or easily went bad after installation, bring about one the the equipment in your vehicle to stop working correctly.

3. You replaced a poor fuse, bring about a device in your vehicle that was not working formerly to begin working. That system has actually an worry causing your vehicle to display the examine engine light. This is much less likely if the examine engine irradiate wasn't on before this.

4. It's a coincidence and another system in your car started to suffer an worry just ~ you changed the fuse. Think it or not, this walk happen also though it is also less likely.

The easiest method to narrow under the problem is to use an OBD 2 reader, such as the one I connected to in the article, to review the problem codes from her car's computer. You can then cross recommendation this code online or through the manual that comes through the reader to uncover out specifically which system is bring about your car's check engine irradiate to illuminate.

Question: I replaced my vehicle's O2 sensor, disconnected and reconnected the battery lot of times, and also even changed its plugs, however the inspect engine light came earlier on ~ a 45 kilometres drive. What have to I perform next?

Answer: If your vehicle is 1996 or newer model, friend should connect its computer system to an OBD2 leader to discover out what error password it's generating.

Once you acquire this code, you'll have the ability to translate it and also gain a better understanding the what is wrong with your vehicle.

If it states it is "out the range," which is an extremely common as soon as a sensor malfunctions, change the faulty sensor. Climate take the procedures outlined in this post to reset the inspect engine light.

A loose or damaged gas cap is in reality a pretty common reason the a examine engine light will certainly come on. Her car's computer probably just needed a tiny help after you solved the issue. Friend did the ideal thing!

Yes, as lengthy as your examine engine light remains off throughout the smog test, you need to be fine. Take it a look at my other post (below) which may be helpful to make details your vehicle passes smog. An excellent luck!


Penny Lister on December 11, 2017:

my inspect engine irradiate was continuing to be on so I replaced the gas cap, but the light to be still on, so ns took the floor cable loose from my battery, pressed the horn for 30 seconds, and also i waited because that 15 minutes to reconnect the cable come the battery. When i walk that, my examine engine irradiate is now off. I have driven the car about 30 miles because then and it is quiet off. Carry out you think I have fixed the problem and do you think i can now pass emmissions?

Kate day-to-day (author) indigenous California ~ above December 07, 2017:


There might only be a couple of reasons why the check engine light would certainly remain. These space in order from the most likely reason to the the very least likely:

Possibility 1 - The trouble that resulted in the computer's error code (which is make the examine engine light illuminate) was not fully fixed. Even if you replaced the sensor, it might not have truly to be a faulty sensor the is the issue. That may have been what the sensor is detecting (i.e. A bigger issue with the engine).

Possibility 2 - there is an issue with the connection to the sensor. I understand you confirm for loosened connections, yet did you check the wiring native the computer to the sensor itself? shot doing this by using an ohm meter to obtain a reading on the resistance throughout just the sensor, then affix the sensor and find the very same sensor wires earlier at the car's computer. Check the resistance between those 2 wires earlier at the car's computer. They must be just around the exact same resistance. If the resistance is significantly greater or reduced than what the resistance was throughout just the sensor by itself, climate you have an concern with the wiring and/or link to the sensor.

Possibility 3 - The car's computer is faulty, this is by much the the very least common. See items 1 and also 2 above first.

I hope this offers you a good starting point. If you would certainly like, short article what certain error code your car's computer system is giving you (read the codes with the OBD 2 reader) and I can provide you much more ideas on wherein to look.

Rick dreves on December 07, 2017:

What if you've done every these procedures and your examine engine light is still on replaced all O2 sensors map sensor inspect for all loosened connections and a good ground however the engine light still on and still provides the exact same code that you simply repaired

Kate daily (author) native California on October 08, 2017:

Hi Paul, i would absolutely start by canceling the fault code to view if the password comes back. If that does climate it may not have been the sensor chin that's the problem, rather it may be what the sensor is detecting. Here are some thoughts that might be helpful:

1 - check for loose or corroded electrical connections in the wiring harness close to the sensor.

2 - are there any other electrical related concerns with the car? If therefore they could be related (like a loose or corroded ground connection wire).

3 - check the vacuum mechanism (i.e. Vacuum hoses and also connectors) for any type of lose or brittle/broken parts. If you have actually a small vacuum hose with a crack in it, the could reason your fault. Shot using a vacuum gauge because that chasing down any kind of issues with the vacuum system.

Hopefully you uncover some of this useful for addressing your problem!
