Check engine light

Check Engine Light Repair in Walnut Creek, CA

The dreaded “check engine light” has been with us for more than two decades. It’s an all-purpose signal that tells you that your vehicle needs professional attention. There are literally hundreds of different conditions that can cause the light to come “on”. At Diablo Auto Specialists, our nationally ASE certified technicians will use state-of-the-art digital diagnostic tools to discover the root cause of the light coming on, and to repair your vehicle.

If your vehicle’s computer has illuminated the check engine light, it is time to visit “auto repair shop near me”, though of course we think that it’s best to come to Diablo Auto Specialists in Walnut Creek. Our technicians are certified by the National Institute for Automotive Service Excellence (ASE), and can offer complete check engine light diagnostics, and can repair any problem your vehicle may exhibit.

There are two states that the check engine light can indicate – steady light means lesser malfunction, blinking light indicates major malfunction.

If the check engine light is flashing, it is recommended that you stop the car as soon as it is safe to do so, and have it towed to an auto repair shop. Driving when check engine light is flashing can cause damage that will be very expensive to repair.

Diablo Auto Specialists is a family owned and operated full service auto repair shop that can offer comprehensive car care. Fortunately, the check engine light can indicate a wide range of problems, and many of them do not pose immediate threat to your vehicle. However, even if the check engine light is in the “steady” state, you should still bring your vehicle to a professional auto repair shop to have it inspected. Driving for prolonged time with the check engine light “on” can results in damage to the catalytic converter – catalytic converter replacement is an expensive repair.

So if the check engine light is not blinking, and the car drives normally, and there is no misfire, if it behaves as it always does, you can drive it home, but should call the “mechanic near me” and make an appointment for professional check engine light diagnostics, and to get the problem repaired.

Sometimes it may turn out to be a simple, and inexpensive fix – worn out gas cap can trigger the check engine light. Faulty sensors, faulty EGR valve, faulty fuel injector, worn out spark plugs – they all can cause the light to come on. On the expensive end, check engine light can indicate catalytic converter failure, which will be an expensive, but necessary repair.

Clients sometimes ask on the phone what will be the cost of the check engine light repairs. Even if you use a scanner to provide us with the code, most of the time we cannot answer this question. Because the trouble codes stored in the computer are more of a road sign, than an answer. Most of the codes require an experienced technician to inspect the system, to use advanced diagnostic tools, and often they require tracing the problem through various subsystems of your vehicle. Needless to say, nobody can do this on the phone – if someone gives you an answer, they are guessing.

At Diablo Auto Specialists we do not guess. We use state of the art digital diagnostic tools to provide you with accurate answers. When you bring your vehicle to our Walnut Creek auto repair shop, you will not only be greeted by our friendly staff, but will also find that your car is in the highly capable hands of our nationally ASE certified technicians.
