1. Understanding the Check Engine Light
The check engine light, also known as the malfunction indicator lamp (MIL), is a signal from your car’s onboard computer that something is amiss. It doesn’t always indicate a severe problem, but it should never be ignored. According to the Environmental Protection Agency (EPA), all cars sold in the U.S. since 1996 are required to have an OBD system to monitor engine performance and emissions. When the system detects a problem, it illuminates the check engine light to alert the driver.
