DTC codes
Look up an OBD-II fault code: what it means on every car or on your make, and how to track it down.
How to read a code

Read the code
Note every stored and pending code your scanner shows, such as P0420.
Find it
Search by code or by words. For a manufacturer code (P1, B1, C1, U1) pick your make: its meaning differs by make.
