Read KBB OBD-II powertrain code references
Copy the fault code shown on your car scanner or inspection report. Your assistant checks the KBB powertrain-code reference list and explains the matching source entry if it is returned.

You receive
KBB’s common powertrain fault-code reference entries with each code, title and brief description. Your assistant checks your known code against the entries actually returned.
Start with your task
Use the KBB powertrain-code reference list to explain [fault code shown on the car scanner or report]. Show the matching title and description only if returned. If it is absent, say so; do not decide a repair from the code alone.
What to know
This is a curated powertrain-code reference collection, not a vehicle scan or a supplied-code search. It does not establish a particular vehicle fault, severity, safe-to-drive decision, repair procedure or repair cost. A missing entry does not make a code invalid.
