Fault-Code Lookup
Check-engine light on? Enter your car or bike's OBD-II fault code to understand what it means, what usually causes it, and how urgent it is — for free.
Common codes
Generic OBD-II codes (starting P0, P2, C0, B0, U0) are the same across makes and apply to cars and most modern fuel-injected motorbikes. Manufacturer-specific codes (P1xxx) vary by make — confirm those with a make-specific scan tool. This tool is general guidance, not a substitute for a professional diagnosis.
How it works
From warning light to fix
01
Read the code
Plug an OBD-II scanner into your car (or a compatible bike) to read the fault code.
02
Look it up
Enter the code above to see what it means, likely causes and how serious it is.
03
Confirm & fix
A code is a clue, not a diagnosis. Have a mechanic confirm the real cause with live data before replacing parts.
