When that little orange light flickers to life on your dashboard, it’s easy to feel a sense of panic—or worse, ignore it altogether. The Check Engine Light (CEL) is one of your car’s most important warning systems, and it's not something to overlook.
Whether you're commuting daily in New Britain or heading out on I-84, your vehicle needs to be in top condition. At our New Britain auto repair shop, we specialize in diagnosing and fixing Check Engine Light issues with precision and transparency. Let’s break down what this light means, what could be causing it, and why expert diagnostics matter.
Your Check Engine Light is part of the On-Board Diagnostics (OBD-II) system in your vehicle. When this light comes on, it means your car's computer has detected an issue within the engine, emissions, or drivetrain system.
It can signal something as minor as a loose gas cap—or as serious as a misfiring engine.
There are hundreds of potential triggers, but here are the most common causes we diagnose in New Britain, CT:
A simple yet common issue. If your gas cap is loose, cracked, or missing, it can affect fuel pressure and trigger the light.
Your O2 sensors monitor unburned oxygen in the exhaust. A failing sensor can decrease fuel efficiency and damage your catalytic converter.
If your car misfires, especially during acceleration or idling, spark plugs or ignition coils may be the culprit.
This component helps reduce harmful emissions. If it fails, your car won’t pass an emissions test and may run hotter than normal.
The MAF sensor measures air entering the engine. If it's malfunctioning, your fuel-air mixture will be off, affecting performance.
Cracked hoses or loose connections can lead to vacuum leaks, causing rough idling, high RPMs, and—yes—the CEL.
Even if your car seems to run fine, a Check Engine Light is not something to delay. Here’s why:
