You can pay a mechanic a bunch of money to read your car's error codes when your check engine light comes on, or you can grab a paper clip and read the codes yourself.
The obd/i code definitions are a good starting point when determining the cause of the service engine light on your car.
The first step in troubleshooting the problem is retrieving the engine fault code. In this guide, we will take a look at how you can read and clear engine fault codes using various scanners.
The connector is usually located under your steering wheel, under the dash. The connector may have a black plastic cover over it and you may have to remove some covers to reach it. The connector is often black and has 12 pins on it, pretty easy to identify.
A test light is used as the flash indicator that will identify the two digit code number. Once a grounded test light is connected to the data port connector turn the key to the "on" position without starting the engine. The test light will begin to flash on then off, count the flashes, when the flashing stops the first digit is complete, then the system will pause and the second digit will begin flashing. For example the test light flashes twice and then pauses and flashes four more times the code number is 24.
