Check Engine Light

Check Engine Light Diagnostics and Repair in

Concord, CA

Randy’s Mobile Mechanical Service offers complete range of mechanical and electrical auto repairs at our Concord, CA facility. Check engine light diagnosis and repair is one of the services we offer.

Your vehicle’s computer can illuminate the check engine light for a number of reasons. Some can be as simple as the fuel cap not holding pressure – simple fuel cap replacement will solve the problem. Other frequent causes of the check engine light include mass airflow sensor failure, spark plug problems, and in the severe cases, it could indicate catalytic converter failure. There are, literally, hundreds of conditions that can lead the computer to illuminate the check engine light. Diagnosing the real cause of the check engine light requires advanced skills and state-of-the-art digital diagnostic equipment. At Randy’s Mobile we provide our technicians with cutting-edge professional diagnostic tools to allow them to efficiently get to the root cause of the check engine light problem. 

What to do if the Check Engine Light is “On”

If the check engine light is flashing on–and–off, as soon as it is safe to do so, pull to the side of the road, turn off the engine, and have the car towed to our Concord, CA facility. Driving your vehicle in this condition could cause severe damage to the engine. 

If the check engine light is “on” but not flashing, and the car drives normally, you can usually continue driving the car, but should get it to a repair shop as soon as possible – prolonged driving with the check engine light “on” can cause catalytic converter damage.

When you bring your vehicle to our Concord auto repair shop, we will diagnose the problem and provide you with a clear explanation of what needs to be done to get your vehicle back in top shape. Any repairs you authorize include:

● 24 months / 24,000 miles warranty

● Same day service completion (in most cases)

● Clear explanation of what needs to be done

● Original Equipment or better quality parts

So when the day comes that your car’s on-board computer turns on the check engine light, call us. We will inspect your vehicle and diagnose the cause of the problem, fix it, and return the car to you – ready for the road.
