REVISION SUMMARY
Under AFFECTED VEHICLES, WARRANTY CLAIM INFORMATION, and SOFTWARE INFORMATION, 2017 Pilot, 2017
Ridgeline, and 2018 Odyssey were added.
BACKGROUND
The PCM software may misinterpret sensor inputs as a deteriorated catalytic converter. Additionally, debris from the high
pressure pump or the fuel injector machining process can cause internal wear or clogging inside one or more injectors.
One or more of the following DTCs may be stored:
 P0420 (rear bank catalyst system efficiency below threshold [bank 1])
 P0430 (front bank catalyst system efficiency below threshold [bank 2])
 P0300-P0306 (misfire)
 P219A (air-fuel ratio variation of cylinder [bank 1, rear bank])
 P219B (air-fuel ratio variation of cylinder [bank 2, front bank])
American Honda is extending the warranty on these repairs to 10 years from the original date of purchase or 150,000
miles, whichever comes first.
CUSTOMER NOTIFICATION
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

REPAIR PROCEDURE
1. Relieve the fuel pressure.
2. Disconnect the negative terminal from the 12-volt battery.
3. Remove the intake manifold and intake manifold base.
4. Remove the high pressure fuel pump cover.
5. Remove the fuel rail cover.
6. Remove the fuel joint pipe.
7. Remove the fuel rail and fuel injectors.
8. Replace the fuel injectors in the fuel rail.
9. Install the fuel rail and new fuel injectors into the cylinder head.
10. Lubricate the tips of the new fuel joint pipe with polyethylene glycol included in the fuel injector kit.
11. Lubricate the threaded areas of the fuel rails and high pressure fuel pump with polyethylene glycol.
12. Loosen the fuel pump mounting bolts.
13. Install the new fuel joint pipe.
NOTE: Do not reuse the fuel joint pipe. Failure to install a new fuel joint pipe will cause fuel leaks.
Page 8 of 10
NOTES
14. Tighten the fuel joint pipe nuts by hand until the tips of the fuel joint pipe are seated on the fuel rails and the high
pressure fuel pump.
15. Loosely install the bracket bolts to secure the new fuel joint pipe to the cylinder head.
16. Tighten the fuel pump mounting bolts to 25 N·m (18 lb-ft).
17. Tighten the fuel joint pipe bracket bolts to 12 N·m (9 lb-ft) and 22 N·m (16 lb-ft) in the order shown.
18. Tighten the fuel joint pipe nuts to 36 N·m (27 lb-ft) in the order shown.
NOTE:
 A crowfoot-type special tool increases the torque applied by the torque wrench. Refer to Torque Specifications on
SIS for details on how to recalculate the torque wrench setting.
 Failure to tighten the fuel joint pipe nuts to the proper torque will cause a fuel leak.
