A Complete List of Free OBD2 Codes for Check Engine Light

If you are staring at an annoying check engine light on your dashboard, you need to learn about OBD2 Codes. On-Board Diagnostics Codes is the way your car keeps track of a wide range of issues. There are OBD2 codes for virtually everything that can go wrong with your car from transmission troubles to fuel injector issues.

The best thing about OBD2 codes? They are no longer a “mechanic’s secret.” Anyone can learn to access and read them easily. That means there is no need to take your car to the dealer the next time your check engine light comes on.

When the check engine light comes on, it is an indicator that you may have a significant problem. You need to check the codes stored by the onboard computer diagnostic system. Years ago, these codes were initially known as diagnostic trouble codes. Today, we commonly refer to them as OBD2 codes.

The first step in understanding OBD2 codes is knowing where to find your vehicle’s diagnostic plug. Many diagnostic plugs are underneath the dashboard, in or under the glove box. 

After you find the plug, pull it gently from its housing. It will more than likely be attached to an additional set of wires. The wires connect to various sets of sensors. Don’t pull hard enough to disengage them. 

Now stick one end of the paper clip or wire into one of the holes in the plug, and the other end into the other hole. Be sure to get the ends as far down into the holes as possible. Once you do this, turn your car’s ignition to the “run” position.

Watch the check engine light on your dashboard and count the flashes to decipher the OBD2 codes. Each long flash represents “10,” and each shorter blink represents a single digit. Say there are four long flashes and one quick flash, that would equate to the number 41.
