Possible Reasons Why Your Check Engine Light is On
The check engine light is one of the most important lights on your dashboard. It’s important to understand what this light means, and what you should do if it comes on. So if your check engine light is on, it’s important to have your vehicle checked by a qualified mechanic as soon as possible to diagnose the problem.
Here are a number of potential reasons why your check engine light might is on:
1. The gas cap is loose
One of the most common reasons your check engine light may come on is because your gas cap is loose. The gas cap is responsible for sealing in the gasoline fumes, and if it's not tight enough, those fumes can escape. In addition to causing your check engine light to come on, a loose gas cap can also lead to decreased fuel economy.
2. You're vehicle is due for an oil change:
Another common reason for your "check engine" light to come on is that you're due for an oil change. Over time, the oil in your car breaks down and becomes less effective at lubricating the engine. This can lead to increased wear and tear on the engine, which can eventually lead to engine damage. Changing your oil regularly is one of the best ways to prevent this from happening.
3. The oxygen sensor needs to be replaced:
The oxygen sensor is responsible for monitoring the amount of oxygen in the exhaust fumes. If the sensor detects that there's too much or too little oxygen, it will send a signal to the computer to adjust the air/fuel mixture accordingly. However, if the sensor itself is faulty, it can cause the "check engine" light to come on. Replacing the oxygen sensor is typically a fairly simple and inexpensive repair.

What We Inspect:
1. We check to see if the gas cap is loose.
The gas cap is one of the most common reasons why the check engine light comes on. A loose or damaged gas cap can cause your car to lose fuel, which can trigger the check engine light. We will inspect the gas cap to see if it is loose or damaged.
2. We check the air filter.
Another common reason for the check engine light to come on is a dirty air filter. A dirty air filter can restrict airflow to the engine, which can cause performance problems. We will inspect the air filter and replace it if necessary.
3. We check the oxygen sensor.
The oxygen sensor is responsible for monitoring the amount of oxygen in the exhaust fumes. If the oxygen sensor is not functioning properly, it can cause the engine to run lean or rich, which can trigger the check engine light.
4. We check for vacuum leaks.
A vacuum leak can cause your car to lose power and can trigger the check engine light. We will inspect your vehicle for vacuum leaks and repair them as necessary.
5. We check for engine misfires.
An engine misfire can be caused by a variety of factors, such as a spark plug that has gone bad or a fuel injector that is not functioning properly. We will inspect your car for engine misfires.
