The check engine light may come on during deceleration due to various issues, such as problems with the engine management system, fuel system, or emissions controls. Common causes include a faulty oxygen sensor, issues with the catalytic converter, or vacuum leaks that affect engine performance when the throttle closes. Additionally, changes in engine load during deceleration can expose existing problems that trigger the light. It's advisable to have the vehicle diagnosed with an OBD-II scanner to pinpoint the exact issue.
