Check Engine vs. Service Engine Soon Light: What’s the Difference?

Dashboard warning lights can be confusing. Many drivers wonder: what’s the difference between a Check Engine Light and a Service Engine Soon Light? At Car Aid Auto Repair, we break it down so you know what to do next.

🔧 Check Engine Light

• Usually yellow or orange
• Indicates a specific issue detected by your car’s onboard computer
• Can be minor (loose gas cap) or serious (catalytic converter failure)
• Should be diagnosed ASAP with a scan tool

🔧 Service Engine Soon Light

• Sometimes yellow or red, varies by make
• Reminder for scheduled maintenance (oil change, filter replacement, inspection)
• Not always urgent, but ignoring it can shorten your car’s lifespan
