EXHAUST EMISSIONS TESTING

IDLE TESTING- For vehicles from 1983 and older

This test is used for most 1983 vehicles and older. The vehicle is tested at idle and (depending on vehicle class) at approximately 25 to 30 miles per hour.

IM 240-For vehicles from 1984-1995

The IM240 test is a chassis dynamometer schedule developed and recommended by the US EPA for emission testing of in-use light duty vehicles in inspection & maintenance (I&M) programs implemented in a number of states.

The IM240 begins by driving the vehicle onto the dynamometer, activating vehicle restraints, properly placing the exhaust collection device, and positioning the auxiliary engine cooling fan. An inspector then “drives” the vehicle according to a prescribed cycle displayed on a video screen. The inspector follows the driving cycle by using the accelerator pedal and the brake to speed up or slow down just as if the vehicle were being driven on a city street. A cursor on the video screen indicates vehicle speed. The inspector adjusts the speed to keep the cursor on the trace. This technique is easily and quickly learned by anyone who can drive a car.

On-Board Diagnostics (OBD)-  For vehicles from 1996 and newer

OBD is an acronym for On-Board Diagnostics. The OBD system consists of one or more computers installed in model year 1996 and newer vehicles that monitors emissions control components in the vehicle's engine, transmission, evaporative system, and exhaust system. If an OBD monitor detects a problem that might cause the vehicle's emissions to exceed allowable limits, a "check engine," or similar warning light is illuminated on the dashboard to alert the driver that something is wrong with the vehicle. By giving vehicle owners this early warning, OBD protects not only the environment but also consumers, identifying minor problems before they become major repair bills.
