A check engine light can be triggered by various issues, ranging from minor to more severe problems. Some common causes include a loose gas cap, faulty oxygen sensor, malfunctioning catalytic converter, or issues with the ignition coil and spark plugs. Addressing these problems promptly is essential to prevent further damage and costly repairs. Ignoring the check engine light for an extended period can lead to severe consequences for your vehicle. A minor issue, if left unresolved, can escalate into a more significant problem, resulting in decreased fuel efficiency, increased emissions, and even engine damage.

"I was recommended to John's Automotive of El Cajon (on Airport Drive) for check engine light diagnosis and repair and was told that the workers know what they are doing and can get most cars fixed and able to pass SMOG. Patrick and Matt in the front office were both friendly and helpful. It is easy to call and reach an employee. I have a 2005 Toyota Camry and the shop was able to correctly identify that the front catalytic converter was failing and also caught cracks in the air intake hose and other issues. They gave good advice for using original equipment manufacturer parts and explained the work and required tests. I felt good about hiring them to do the repair work. They were able to schedule the repair right away and did a good job fixing my car. I recommend using John's Automotive for car diagnostics and repair."
