EDITOR’S NOTE: This article revises the previous version posted in January 2022.
When diagnosing a Fit within the above VIN range with a misfire complaint, start by doing service bulletin, 21-007
(Carbon Buildup with Misfire DTCs) instead of replacing fuel injectors. These vehicles use an improved injector design that
addresses the failures that may have occurred in previous model years. In fact, fuel injectors within the above VIN range
with misfire complaints were collected and found to have no defects that required part replacement. Replacing those
injectors may have reduced the number of misfires temporarily, but most likely didn’t address the actual cause of the
misfire. The recommended repair for these vehicles is to do the intake valve cleaning procedure described in service
bulletin 21-007, (Carbon Buildup with Misfire DTCs).
NOTE:
• This bulletin also includes information about a PGM-FI software update that may be available for certain vehicle model
years.
• Injector replacements for misfire prior to doing service bulletin 21-007 may be subject to debit.
