Understanding Your Check Engine Light

Depending on your car’s year, make, and model, this could relate to various systems such as the engine, transmission, brakes, or suspension. Here, we’ll address some common questions and debunk myths about the check engine light.
Frequently Asked Questions
1) Can you keep driving if the light comes on?

2) The light went off by itself. Is everything okay now?
Not necessarily. Check engine lights can turn off temporarily even if the problem persists. The vehicle's computer retains information about the issue, so it's wise to get it checked to prevent long-term problems.
3) What should you do if the light stays on?

This light acts as a warning for various systems in your vehicle. Similar to an error message on a computer, it alerts you to a malfunction?"mechanical, technical, or software-related.
Resetting the Check Engine Light
When the check engine light is on, it indicates that fault codes are stored in your vehicle's onboard computer. These codes are crucial for diagnosing the problem accurately.
