In addition, a sticker with the "engine code" and "serial number" is affixed to the back of the cylinder head cover.

The first three digits describe the mechanical structure of the engine and are still stamped on the engine. The fourth digit describes the engine output and torque and depends on the Engine Control Module (ECM). Four-digit engine codes are found on the type plate and vehicle data label. It can also be read via the ECM.
