What is the most common reason for the check engine light on a 2025 Toyota Camry?

• One of the most frequent causes is an emissions-related sensor fault — oxygen sensors or catalytic efficiency codes are common.

• Addressing these early prevents secondary damage such as catalytic converter failure, which increases repair cost significantly.
