How Do I Reset My Check Engine Light So it Stops Turning On?

We get it here at Ideal Automotive. Your check engine light is annoying you and you just want it to turn off. You cannot afford an expensive auto repair and your car is running just fine, so why does the light keep turning on? The truth of the matter is you can try to turn off the check engine warning yourself using one of the hacks that you might find online, but this won’t prevent it from turning back on if there’s something wrong with your automobile. Let’s talk about this further.

Check Engine Warning Purpose

Your check engine light is there to alert you of engine trouble. As you know, your vehicle’s dashboard has many lights and gauges that keep you abreast of how your car, truck, or utility vehicle is running. For example, your temperature gauge lets you know that your engine is not running too hot and your oil light alerts you when the oil is too low. The check engine light also alerts you when something is going wrong, and what is going wrong does not have a light of its own.

Reasons Why the Check Engine Light Is On

For example, if your vehicle has a vacuum leak and there is too much air in the engine, the engine control module (ECM) will turn on the check engine warning because the air and fuel mixture in the combustion chamber has too much air in it. Other reasons why your check engine warning comes on include

  • Catalytic converter failure
  • Electrical system problems
  • Exhaust system problems
  • Fuel system problems
  • Loose gas cap
  • Mass airflow sensor failure
  • Oxygen sensor failure
  • Transmission problems
  • Worn or misfiring spark plugs

As you can see, these are all causes for concern, which is why it’s not a good idea to bypass your check engine light warning. Unless you tighten your gas cap and the light turns off, there is something wrong, and if you keep driving your automobile you run the risk of causing additional damage.

Consequences of Trying to Bypass the Check Engine Light

This damage is the primary consequence of bypassing your check engine warning. For example, if you ignore an exhaust system problem, you might end up becoming ill or worse because you have carbon monoxide seeping into your cabin. It’s much better to find out why your check engine light is coming on.

Another consequence of bypassing the check engine warning is you will void any extended warranty you have on your automobile. Turning the light off yourself will render the warranty useless when you need it the most. Instead of bypassing the light, call Ideal Automotive in Blaine, MN. We’ll get to the bottom of the problem.
