Vehicle exhaust emissions have been a contributor to air pollution since the automobile first appeared on the dirt roads of the early 1900s. But it was not until the mid 60\u2019s that efforts were initiated to reduce those emissions.<\/p>\n

By the mid-90\u2019s, refined improvements to automotive engines and related systems had made major strides in dropping hydrocarbon emissions to very low levels. In fact, almost zero. Emission control systems had come of age.<\/p>\n

With these control systems came the need to confirm proper operation. Thus onboard diagnostics were born. In 1996 the On-Board Diagnostic version 2 (OBD2) system arrived and with it came the often maligned Check Engine Light<\/strong> (CEL).<\/p>\n

Located in the instrument panel, this warning light is sometimes called the Malfunction Indicator Light (MIL). For this article we will exclusively use the term CEL. Just to clarify, the CEL is definitely your friend. Let\u2019s find out why.<\/p>\n

Before we launch into this, prudence would dictate the following: Go take a look at your owners\u2019 manual and identify what the CEL and all the other instrument panel warning lights look like. Familiarize yourself with their functions.<\/p>\n
