Can You Drive on the Highway with the Engine Yellow Light On?

[ClaytonFitz]

You should not drive on the highway with the engine yellow light on. The yellow engine light indicates a fault in the engine, meaning it can still operate temporarily but requires inspection and repair. Reasons for the engine warning light to illuminate: Poor combustion state, engine knocking, poor fuel quality, dirty engine cylinders with carbon deposits, or the computer failing to retrieve engine data. Effects of the engine light being on: When the engine warning light is on, there are usually some abnormal conditions present. If not addressed promptly, it can lead to deteriorated vehicle exhaust quality, polluting the environment; increased fuel consumption, wasting petroleum and financial resources; elevated combustion chamber temperature and accelerated wear, potentially causing premature engine damage; engine oil burning, increased engine noise, affecting driving and passenger comfort.
