About errorcodefacts

Most pages about error codes list the same possible causes in the same order. We wanted to know which causes actually show up in the records, so we built pages around them.

errorcodefacts starts with car trouble codes and the data NHTSA publishes about them. Each code page combines owner complaints with the service bulletins manufacturers send to their dealers, and explains in plain language what to check first.

We are independent and not affiliated with NHTSA or any manufacturer. See the methodology for how the numbers are produced.
