What can cause a check engine light to come on?

A check engine light can be caused by a variety of conditions, including ignition problems, emissions faults, fuel system issues, sensor failures, air leaks, catalytic converter concerns, and electrical problems. The vehicle's computer records information about the detected fault, but additional testing may be necessary to determine what actually caused it.

Can I drive with my check engine light on?

A solid check engine light with no noticeable drivability problems may allow you to drive the vehicle temporarily while arranging an inspection. However, the warning should not be ignored indefinitely. If the light begins flashing or the vehicle is shaking, losing power, running poorly, or displaying other serious symptoms, stop driving when it is safe to do so and have the vehicle evaluated.

Why does my check engine light keep coming back?

A recurring check engine light usually means the underlying condition has not been corrected or an intermittent problem continues to occur. Clearing the code can turn the warning off temporarily, but it does not repair the cause. If the same fault returns, additional diagnostic testing may be necessary to determine exactly what is causing it.

Does a diagnostic code tell you exactly which part needs to be replaced?

Not necessarily. Diagnostic trouble codes identify a system or operating condition that the vehicle computer has detected. A technician may need to test wiring, sensors, connectors, mechanical components, or related systems before determining which part is actually responsible. Proper diagnosis helps prevent unnecessary parts replacement.

That Warning Light Deserves a Proper Diagnosis

A check engine light can appear without much warning. Your vehicle may still start, accelerate, and drive normally, making it tempting to ignore the illuminated symbol.

That isn't always a good idea.

The warning can be associated with something relatively minor, but it can also point toward an engine performance, emissions, fuel, ignition, or electrical problem. Finding out what triggered the light gives you an opportunity to address the issue before it becomes a larger repair.

At Brady's Service Center, we provide check engine light diagnostics in Moorhead, MN for cars, trucks, SUVs, and other vehicles. Our technicians use modern diagnostic equipment and hands-on troubleshooting to determine what is happening with your vehicle.
