Will Check Engine Light Reset Itself?

Most cars have a check engine light that can be triggered when there’s a problem that could require you to check the engine soon. This can be triggered randomly whilst you’re driving, and chances are that you’ve dealt with it before because this light can be triggered several times during a car’s lifetime.

Your cars OBD system is a computer system that continuously monitors the electronic sensors of engines and emission control systems, which include the catalytic converter, whilst you’re driving to make sure they’re constantly working. The check engine light can be triggered due to some parts of your car malfunction and this can include a whole host of things and these can be hard to detect.

Why Your Check Engine Light is On

If your car engine control unit detects a problem it can’t regulate without assistance, then your check engine light will turn on. The EGU in your car is the brain of the engine and it controls all the functions of the engine. It can do things such as regulating and maintaining the amount and fuel and air mixture to help increase horsepower within your engine.

When the EGU finds a problem, it can regulate or maintain, the check engine light on your dashboard will turn on – it’ll either stay on or start blinking and this all depends on the nature of the problem. If it’s blinking, there’s an emergency within your car and you should stop driving right away and get it checked by a mechanic. If the light just stays on, then it’s not an emergency but you should still get it checked out.

Resetting Check Engine Light

If the check engine light is on and you know that the problem with your car isn’t severe, there are ways to make the check engine light go away. Heck, you may have even fixed the problem, but the check engine light still remains on.

1. Continue Driving and Wait for it to Go Away

The first and easiest way to get the check engine light to turn off is to continue driving and to allow to take car of it. If the problem is minor, your control unit will recheck the problem its detected and If there’s a mishap and the problem can be regulated, then the light will naturally switch off itself. You just have to continue driving your car like you normally would. If the check engine light has remained on for a few days now, the problem couldn’t be regulated so you’ll have to use other methods to get rid of it.

2. Restart Your Car

Another way to get rid of this is to restart your car multiple times. Turning your car off then on three in succession might get the check engine light to reset. Some vehicles can automatically reset problems that caused the light to come on. In order to do this, you need to insert your ignition key and turn your car on for a second then turn it off for a second. After doing these 3 or 4 times successfully. Once you’ve done this, turn your car back on and check if you were able to get rid of the check engine light.

3. OBD2 Scanner

If you experience problems with your car regularly then you can use an OBD2 scanner. An OBD2 scanner is a diagnostic system that comes with your vehicle and it’s used to check the engine and other vehicle systems. It also communicates all the possible glitches that happen to them. You can use an OBD2 scanner (View on Amazon) to get rid of a check engine light.

When you see the check engine light come on, you can connect the OBD2 scanner to the OBD connector that is under the steering portion of most vehicles. Once this is done, you can switch on your car’s ignition and turn all the other devices connected into the car. Once the computer and car are connected, press the red button on the scanner so it can check everything going on in the engine control unit.

After the scan is complete, you can write down all the error codes that the scanner diagnosed. Then, use your car’s manual to decode the problems. After you’ve decoded the problem and the problem is detected, you can take appropriate measures to sure the problem. This may require certain parts to be checked.

After you’ve fixed the problem with your car, press Erase/Clear on the scanner. Restart your car and turn on the ignition and the check engine light should no longer be there.

4. Disconnect Battery

This method will involve you removing all of your batteries positive and negative terminals. You’ll then need to drain any electricity that available in your car’s capacity by turning the lights on or holding the horn for 30 seconds. Once the car’s electricity is disconnected, leave your car one for 15 minutes. After, connect all the batteries positive and negative terminals making sure that they’re tightened. Once this is done, turn your car on.

If you’ve turned your car on and you can still see that the check engine light is on, then you’ll know that there’s a serious problem with your car. In this case, you can take it to the mechanic and get it checked out.
