Stop by your local store for free engine code scanning on most obd ii vehicles. The advent of computerized engine controls in the 80s meant the check engine light cel on the dash alerted drivers to potential problems. An illuminated cel means that a sensor or a system on the engine has registered a reading that s out of normal operating spec and the engine computer has stored a trouble code. Keep in mind that vehicles made since 1996 require an obd ii reader but some scan tools are able to read both obd and obd ii codes.

When the computer determines that something has gone wrong it logs a diagnostic trouble code and turns on the check engine light letting you know that you can scan for the code with your code reader. If it turns out that your code isn t serious this device can turn off that annoying check engine light. When the mil is illuminated getting to the engine codes themselves is a simple process. A tech can connect a diagnostic code reader or scanner device to a port in the passenger compartment often under the steering column and the engine codes will show up on the scanner usually showing the code itself and a one line definition.
