What is Bank 1?

Bank 1 is the side containing cylinder 1.

What is Bank 2?

Bank 2 is the other side on V or flat engines; inline engines have only Bank 1.

Do paired codes prove an engine has two banks?

A paired definition does not prove that your engine has both banks.

Reference-family membership is not proof that a code applies to every listed ECU or vehicle. Runtime-ready definitions are not physical-vehicle validation. Unavailable readings must not be treated as zero. App and hardware sale availability must be checked separately.
