The emission calibration number label is attached to the left side door or the left door post pillar. This label plate identifies the engine calibration number, engine code number and the revision level. These numbers are used to determine if parts are unique to specific engines. The engine codes and calibration are necessary for ordering parts and asking questions related to the engine.
