Why is your check engine light on?

The “check engine” light or “service engine soon” light can be caused by one or more sensors along the emissions system of a car.

Don’t ignore this light — it means REPAIR NOW!

Luckily modern cars are easy to diagnose. All I need to do is plug in my trusty code reader, and presto — I know exactly what needs to be fixed. No guessing necessary.

Recently I fixed a 2004 Suzuki Forenza with a flashing service engine light. I gave it a complete tune-up and got all of the service work up-to-date. It’s important to keep your car well maintained so that major repairs are avoided.
