Is there a printable OBD-II trouble code list?
What a printable list covers
Most printable lists focus on generic powertrain codes, which start with P0. These cover common areas like misfires, fuel trim, oxygen sensors and emissions systems. A list can be handy in the garage when you want a quick look at a code you just read.
A list usually will not include the detailed causes for your exact vehicle. Codes such as P1 series or body and chassis codes may vary by brand, so the list may only give part of the story.
- Generic P0 codes cover many common faults
- Manufacturer P1 codes vary by brand
- Keep the date of the list in mind
- Use the list as a reference, not a repair plan
Safe ways to use a list
Download lists from a source you trust, such as a known repair site, an automaker or a university or library. Save the file and scan it for odd popups before you open it. Printing a copy is a good idea for older cars with no phone connection.
Write the code and the date you read it on a list, along with any symptoms. That record helps a mechanic if the problem comes back.
- Download only from trusted sources
- Scan files before opening them
- Write down codes with dates and symptoms
- Print a copy for the garage
Common mistakes
- Assuming a generic list explains every code on your specific vehicle.
- Opening a file from an unknown site without scanning it first.
- Ignoring symptoms that do not match the code description.
