Check Engine Light On?

Don’t Panic — But Don’t Ignore It Either

We’ve all been there — you’re driving along, and suddenly that little orange engine icon lights up on the dash. At K&M Automotive in Woodinville, we specialize in accurate, honest, and efficient diagnostics when your Check Engine Light (CEL) comes on.

Whether it’s something simple or a sign of a deeper issue, we’re equipped to get to the root of the problem — and get you confidently back on the road.

What Is Meant by the Check Engine Light?

Your car’s onboard diagnostics system (OBD-II) includes your check engine light. The light alerts you when the system notices something that isn’t typical, whether it’s engine performance, pollution, fuel supply, or sensors.

Typical reasons include:

• Inaccurate mass airflow or oxygen sensors
• Ignition coil problems or misfires
• Damaged or loose gas cap
• Catalytic converter failure
• Issues with the fuel system or injector
• Problems with the emissions system

Some reasons are minor, but if left unchecked, they can cause major engine damage or decreased fuel efficiency.

Advanced Diagnostics at K&M Automotive

Many shops rely on a basic scan tool to read a generic code — but that often only tells part of the story. At K&M Automotive, we go deeper with factory-level diagnostic tools and expertise to pinpoint the issue with precision.
