Will The Check Engine Light Go Off After Tightening The Gas Cap?

The gas cap is one important part of your car; it ensures that the air in your tank is sealed. In case you’re having issues with your gas cap, then there’s a chance that your check light might be on. Thus you may want to replace your cap if you notice that it is loosened or damaged and broken. 

So yes, you can say that if your gas cap is loosened, it can lead to fuel leakage, which can make the engine light turn on, and by simply tightening the gas cap, you can solve the issue. 

What Is The Most Common Reason For Check The Engine Light?

If you’ve noticed that your check light is on, and you don’t know why there could be anything from a bad catalytic convertor to faulty wirings. There are a few reasons that this light might activate, so we’ll go through some common of them :

  • Malfunction in oxygen sensor 

Your engine’s oxygen sensor sits in your exhaust pipe, determining whether there’s enough oxygen in the exhaust gases from the motor. This is a crucial job because if the sensor doesn’t work properly, it can alter fuel-burning efficiency and fuel economy. So a failing oxygen sensor can trigger to turn on the check engine lights. 

  • Faulty spark plugs

An issue with your spark plugs can also cause a check engine light to turn on. The problem could be from plug wires and spark plug caps as well. Also, if you’ve recently installed new spark plugs and the light is still on, the problem might be with your ignition coil or ignition module. 

  • Bad catalytic convertor 

Your catalytic converter is a device that converts poisonous Catylenic Oils into less harmful carbon dioxide fuel. You can’t see it on your dashboard, but it is necessary and works fine. If your catalytic converter doesn’t work properly, you will notice an issue with your check engine light coming on. 

  • Bad fuel pump

A bad fuel pump can be triggered if your gas tank has been low for a long time or the gas cap is not installed properly. If one of these inspections didn’t find any problem, this could be something else. Get your fuel pump tested because if it’s not working, you will be unable to start your car.

It can be either a loose terminal or damaged wiring. If the problem is in the wiring, you may want a mechanic to check this out because you don’t want to cause further damage by driving.

How Long Does It Take For The Check Engine Light To Reset?

It does not take much of your time to reset the check engine lights, and it’s only a few minutes if you reset it by disconnecting the battery and then reconnecting it. 

Most of the time, the check engine light will reset when you restart your car. But if it does not, you have to drive a few miles or up to 20 minutes with no lights on your dashboard. 

Sometimes this happens mostly because of a misfire when the spark plugs cannot ignite the fuel properly. 

When this happens, your check engine light is triggered automatically. So after you drive a while with it off, your vehicle’s computer identifies that the misfire has been fixed and therefore turns off the check engine lights on its own.
