What Happens If You Ignore the Light?
A consistent check engine light (CEL) often indicates emissions issues that can reduce fuel efficiency by 20% or more. If these problems are not addressed, they can lead to rich fuel mixtures that damage spark plugs and the catalytic converter—transforming what could be a $75 sensor replacement into a costly four-figure repair for the exhaust system. Additionally, a blinking CEL is even more concerning, as it signals active misfires that can overheat the catalytic converter and potentially melt its internal components within minutes. Addressing these issues promptly is essential for both financial savings and environmental protection.

Upon your arrival at Zepeda Auto Service, our skilled technicians utilize advanced, high-end diagnostic scan tools that accurately interpret manufacturer-specific P-codes, pending codes, and Mode-6 data.
