    What caused the light to turn on?

    • The Check Engine light is your car’s response to the computer that monitors the independent systems of your car, so when it turns on, a problem could be occurring in a few different locations. For example, the computer monitors the brakes, steering, engine temperature and other systems by monitoring a variety of sensors which represent the individual states of these systems. If any of these sensors reaches its preset threshold for triggering, the car’s computer will turn on the Check Engine Light to notify the driver. The best feature about the Check Engine light is that it usually turns on when even small problems are detected in any of the systems. It is important to pay attention to the light because it also alerts drivers of poor fuel mileage, reduced performance or excessive exhaust emissions, and small problems that can be approached immediately before they turn into big, expensive repairs.

    What to do when it comes on?

    • The simplest way to handle this situation is to visit South Western Motors, where we will read the memory to see what fault the computer is reporting. We can identify whether the problem is as simple as a loose gas cap, or can do more extensive testing if required. We have all the equipment and information needed to determine and correct the problem. In the event the problem is something covered under the manufacturer’s warranty, we will notify you, so you can have it repaired at your dealer free of charge.

    How soon after the "Service Engine Soon" light turns on, do I need to bring my car in?

    • The most obvious answer, of course, is to get the engine checked. But many people do nothing, perhaps fearing an expensive repair bill. Some drivers with older cars want to squeeze out as many remaining miles as possible without visiting a service garage. But before they can pass their state's vehicle inspection, they have to get the light turned off. And a state inspection is a good motivator for dealing with the problem. If the light is lit, there's a good chance the car is releasing excess pollutants or consuming too much gas. Call South Western Motors and we will get your car towed into our shop and investigate it for you. 909.889.9539

    What does it mean if my "check engine" or "service engine soon" light comes on?

    • There are many sensors and computerized components that manage your vehicle’s engine performance and emissions. When one of these fails, the "check engine" light is illuminated. Although your car may seem to run fine, it is important to have the issue addressed to prevent needing significant car repair. For further information, check out our check engine light page.

    My technician turned the light off and it came back on a week later. Why?

    • The Onboard Diagnostic (OBD) system is consistently performing a variety of “self-tests” to determine if your vehicle is working as efficiently and cleanly as possible. When a potential problem or failure is identified, the system will compensate if possible, and many of these tests are delayed or turned off. This is especially true if you have continued driving with the check engine light on for several days. Once repairs are completed, the OBD system resumes its self-testing process, and some of these tests require specific conditions to provide thorough and accurate results. For example, one requires an 8 hour delay before starting the engine to provide accurate results while another requires the vehicle to be driven for several minutes above 50 mph. This is why the testing phase is so important to scheduling and conducting a proper repair the first time.
