Almost every vehicle built from the early 1990's onward contains a small component called a powertrain control module (PCM) that electronically controls parts and runs diagnostic tests. Function A powertrain control module is a printed circuit board computer housed in a heavy duty case that can withstand the extremes of temperatures normally experienced inside a vehicle's engine. The module constantly sends electronic signals to all of the different components in the engine, and tests the temperature and airflow around them, to check on the status of their operation. When a component is not working properly, the module turns on the check engine light on your vehicle's dashboard.
