| ONLW8V03292021 | 2021-04-06. Service bulletin. "Owner Notification Letter - On some 2016-17 Pilot, 2017 Ridgeline, and 2018 Odysey models, the malfunction indicator light (MIL) may come on if one of the following diagnostic trouble codes (DTCs) are 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]) Depending on which DTCs were stored, the powertrain control module (PCM) may need the PGM-FI and A/T software updated. Additionally, the fuel injectors may need to be replaced. 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. This warranty extension provides coverage for the original owner and any subsequent owners. No action is required on your part unless you experience a problem." |

| A20-100 | 2021-02-18. Service bulletin. "Service Bulletin - 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." |
