Why the Ram 1500 Check Engine Light Matters
The RAM 1500’s check engine light is an early warning system for engine, emission and transmission problems. Ignoring the light can lead to reduced fuel economy, failed inspections or damage to expensive components like catalytic converters.
- Steady light: Indicates a stored fault—schedule diagnostics soon.
- Flashing light: Signals an active misfire—reduce throttle immediately and repair before driving further.
- Best practice: Scan for codes, repair the root cause, then clear the MIL with a scan tool.
