It's a common misconception that the Check Engine Light is a sign of something seriously wrong with your car. While it can indicate major issues, it can also be something as simple as a loose gas cap.
Here's why the Check Engine Light might be on:
* Emissions System: The most common reason is a problem with your vehicle's emissions system, like a faulty oxygen sensor or a clogged catalytic converter.
* Engine Performance: It can also indicate issues with your engine, such as a misfire, a vacuum leak, or a problem with the fuel system.
* Other Sensors: The Check Engine Light can be triggered by a faulty sensor, like a mass airflow sensor or a temperature sensor.
What to do when the Check Engine Light is on:
1. Don't panic. The Check Engine Light doesn't necessarily mean your car is about to break down.
2. Get your car diagnosed: The best way to determine the cause of the light is to have a mechanic scan your car's computer system. They'll be able to read the "trouble codes" stored in the system, which will give them a clue about what's causing the light.
3. Don't ignore it: While the light may not be a major problem immediately, it's important to get it checked out as soon as possible. Ignoring the Check Engine Light can lead to more serious and expensive repairs down the road.
Important Note: The Check Engine Light doesn't differentiate between manual and automatic transmissions. It's a general warning that your car's computer system has detected a problem.
