Check Engine Light Repair Near Me
Doral’s Auto Repair, the premiere auto repair shop in San Leandro, offers broad range of automotive services, including check engine light repair. Contrary to popular opinion, just reading the error codes is rarely sufficient to diagnose the root cause of the check engine light. In most cases, it takes work of a highly trained technician to follow the “road-signs” that are the error codes stored in the computer.
The check engine light is activated by your vehicle’s onboard diagnostic system, often called OBD-II. When the computer detects something outside its normal range, it stores a trouble code and switches on the warning light. Sometimes the cause is as simple as a loose fuel cap, while other times it could be a failing catalytic converter or a problem with an oxygen sensor. Addressing this problem in a timely manner helps prevent more serious damage.
Our ASE-certified technicians use advanced diagnostic equipment and years of experience to quickly identify the cause of the check engine light. The light often appears alongside other symptoms such as rough idling, stalling, poor fuel economy, unusual exhaust smells, or strange knocking sounds.
At Doral’s Auto Repair we see codes like P0420, which relates to catalytic converter efficiency below a certain threshold, lean codes such as P0171 or P0174 that are commonly caused by vacuum leaks or dirty mass airflow sensors, we also see small EVAP leaks, often flagged as P0442, which can stem from cracked hoses or worn gas cap seals, as well as oxygen sensor circuit faults like P0130. When we see engine misfire codes, like P0300, they are frequently linked to worn spark plugs, ignition coils, or fuel injectors. In all cases, a highly trained technician needs to investigate which component caused the check engine light to illuminate – it is one thing to just read the code, something we do for free, it is another entirely to perform full diagnostics to find the cause of the problem.
Once we identify the cause of the check engine light, we will let you know what repairs are needed, and proceed only with your approval. We offer OEM-quality parts and provide clear explanations or the work to be done. All repairs are backed by a 36-month/36,000-mile nationwide warranty, ensuring your peace of mind.
