BACKGROUND
Due to an improper PCM calibration, after starting the engine the PCM cannot properly adjust the air-fuel ratio under
certain conditions and the on-board emission-related diagnostic system may not appropriately detect a malfuction. As a
result, vehicle emissions may exceed applicable emissions standards and the vehicle contains an improperly functioning
on-board emission-related diagnostic system that violates applicable state and federal standards.
NOTE
Vehicles previously repaired under service bulletin 17-023, Emissions Recall: 2012 Civic PZEV PCM Update must have
the PCM software updated with the software listed in this bulletin.
