How to Check Car Engine Codes
What Are Engine Codes?
Engine codes are diagnostic trouble codes (DTCs) that are stored in the car’s computer when a problem is detected. These codes can help you identify the source of the problem and get it fixed.
How to Check Engine Codes
Using a Code Reader
The easiest way to check engine codes is to use a code reader. This is a small, handheld device that plugs into the car’s diagnostic port. Once connected, the code reader will display any DTCs that are stored in the computer.
Using a Smartphone App
There are also a number of smartphone apps that can be used to check engine codes. These apps typically use Bluetooth to connect to the car’s computer and display any DTCs that are stored.
Manually Checking the Codes
If you don’t have a code reader or a smartphone app, you can also manually check the engine codes by following these steps:
- Locate the diagnostic port. This is typically located under the dashboard on the driver’s side.
- Insert a paperclip into the appropriate hole in the diagnostic port.
- Turn the ignition key to the “On” position, but do not start the engine.
- Count the number of times the check engine light flashes.
- Repeat steps 3-4 until you have a series of five flashes.
The series of flashes will correspond to a specific DTC. You can look up the DTC in a repair manual or online to find out what the problem is.
What to Do if You Find an Engine Code
If you find an engine code, the first step is to identify the source of the problem. You can do this by referring to a repair manual or by searching for the DTC online.
Once you have identified the source of the problem, you can take steps to fix it. This may involve replacing a faulty part, repairing a damaged component, or simply resetting the computer.
Conclusion
Checking car engine codes is a simple and effective way to identify and fix problems with your car. By following the steps outlined in this article, you can quickly and easily get your car back on the road.
