Does check engine light have to do anything with oil light?

No, the check engine light and the oil light are separate warning systems that indicate different problems. While they can sometimes be related indirectly (e.g., a faulty sensor could trigger both), they are fundamentally independent.

* Check Engine Light: Indicates a problem detected by the vehicle's onboard diagnostic system (OBD). This could be anything from a minor issue like a loose gas cap to a serious problem like a failing catalytic converter. A scan tool is needed to determine the specific code(s) triggering the light.

* Oil Light: Indicates a problem with the engine's oil pressure or level. This is a much more serious and immediate warning, indicating potential engine damage if ignored. Low oil pressure means your engine isn't getting properly lubricated, leading to rapid wear and failure.

In short: The check engine light is a broad warning; the oil light is a critical warning demanding immediate attention.
