Check Engine Light Diagnostics

The onboard computer diagnostic system (OBD II) in your vehicle is responsible for monitoring the emissions control systems, including catalytic converters, fuel caps and parts of the chassis. Because of the many components monitored by this system, there are several underlying factors that could trigger your check engine light to pop up on the dashboard. Some Walnut Creek automobile owners opt to ignore this light until they see evidence of a concrete problem, but this is a mistake that could lead to serious damage to your automobile. At Walnut Creek Import Service and Sales, we suggest that you schedule check engine light service the first time you see the display light up. We’ll run car diagnostics to determine the source of trouble and provide repair services for the issue.

Common Error Codes & Problems

Did you know that there are at least 49 different error codes that auto diagnostics could generate? Technicians require specialized equipment, such as scanners and diagnostic monitors, to determine the cause of these alerts. As we run tests and perform inspections to uncover the issues that trigger the lights to come on, we have learned to expect some common concerns. They most likely include emissions failures, malfunctioning oxygen sensors, loose or faulty gas caps, damaged catalytic convertors, faulty mass airflow sensors and failing spark plugs. If you ignore the check engine light, you could miss the chance to correct minor issues before they become major, and could end up paying much more to fix serious damage to your vehicle.
