Can I drive a Lexus with the check engine light on?
The short answer is that it is generally not recommended to drive a Lexus with the check engine light on.

Understanding the Check Engine Light
The check engine light, also known as the malfunction indicator light (MIL), is a warning signal that illuminates on the dashboard of a vehicle when the onboard diagnostic (OBD) system detects a problem. This system monitors various components of the engine and emissions control systems, and the light is triggered when it senses an issue that could affect the vehicle's performance, fuel efficiency, or emissions.
When the check engine light is on, it means that the vehicle's computer has detected a trouble code, which can indicate a wide range of problems, from a loose gas cap to a malfunctioning catalytic converter. Ignoring the light and continuing to drive can potentially lead to further damage and more expensive repairs.

- If the light is steady (not flashing), it may be safe to drive the vehicle, but it is important to have the issue diagnosed and repaired as soon as possible.
- Driving with the check engine light on can potentially lead to decreased fuel efficiency, increased emissions, and further damage to the vehicle's systems.
