Can You Continue Driving with a Check Engine Light On in Midland, ON?

Blog Apr 23rd, 2026

The check engine light is part of your vehicle’s onboard diagnostics system, often called OBD-II. When something falls outside the normal operating range, the system stores a fault code and turns the light on to let you know. The good news is that not every check engine light means you need to pull over right away, but it’s also not something you should ignore. It could be triggered by something simple, such as a loose gas cap affecting fuel vapour pressure in the EVAP system, or something more involved like a misfire, fuel system issue, or emissions control fault. Read on with our team at Bourgeois Motors Ford as we walk through whether you can continue driving with a check engine light, depending on whether the light is solid or flashing.

Is the Check Engine Light Solid or Flashing?

Before we get into what each one means, it helps to know what is normal. When you first switch the ignition on before starting the engine, the check engine light will usually turn on briefly. This is just your vehicle doing a system check to confirm the bulb is working and to show that the onboard diagnostics system is ready for Inspection and Maintenance (I/M) testing. Normally, it stays on until the engine starts and then turns off if everything is operating in order. Once the engine is running, here is how to tell what the light is trying to say.

When the Check Engine Light is Solid

If the check engine light illuminates while the engine is running, it means the On-Board Diagnostics system has detected an error in the vehicle’s emissions control system. In many cases, the vehicle may still feel normal, but a fault code has been stored that needs to be diagnosed. It could be related to anything from fuel vapour control to sensor performance. In this case, you can usually continue driving for a short period, but it’s important to book a service appointment at Bourgeois Motors Ford so the issue can be pinpointed before it develops further.

When the Check Engine Light is Flashing

What if the light continuously flashes while driving? That indicates a more serious issue, often an engine misfire. When this happens, continuing to drive may result in reduced engine power or, worse, cause the engine to stop. In some cases, ignoring this warning can lead to component damage that may not be covered under warranty. In this situation, it’s best to have your vehicle inspected as soon as possible at Bourgeois Motors Ford.
