Check Engine Light

at CW Exhaust & Auto Care of Olympia

You may be wondering why your "Check Engine Light" is on. A number of different things could be causing this, including a loose gas cap, a spark plug or wire that needs to be replaced, oxygen sensor that needs to be replaced, faulty ignition coils, or your catalytic converter may need to be replaced, among other possible issues. Catalytic converter trouble is a problem primarily because this part won't fail unless there is an underlying problem. Ignoring this warning can compromise your vehicle's performance or even damage to your engine.

Bring us your car or truck when you see "Check Engine" or "Service Engine" light up on your dashboard. We'll diagnose the issue and recommend a solution. We want our customers to have the opportunity to feel comfortable in their vehicle. You can leave the repairs and services to our professionals, but please don’t hesitate to ask us questions about why a service is needed or how an issue occurred. Give us a call at (360) 489-0589, and we will be happy to assist you.
