Emission Warranty Extension: MIL Is On With DTC P0420 or P0430
(All States Except CA, CT, ME, MA, NY, and VT)

VIN:
Dear :
In some cases, the electronic control module (ECM) misinterprets sensor inputs as a warm-up three-way catalytic converter
(TWC) deterioration and turns the malfunction indicator lamp (MIL) on with diagnostic trouble code (DTC) P0420 or DTC P0430
(catalyst system efficiency below threshold) stored.
To ensure your confidence in our product, American Honda is extending the warranty on the TWC 6 months from the launch of
the campaign or 200,000 miles, whichever comes first.
This warranty extension expires December 31, 2018.
This extension of the factory warranties provides coverage for the current owner and any subsequent owners. The warranty
extension is valid except for any vehicle that has ever been declared a total loss or sold for salvage by a financial institution or
insurer, or has a branded, or similar title under any state's law..
What should you do?
If the MIL indicator in your vehicle comes on, go to any Honda dealer to have your vehicle inspected. If DTC P0420 or P0430 is
stored, Honda will replace both the front and rear TWCs, and update the software in your vehicle free of charge.
Lessor Information
Please forward a copy of this notice to the lessee.
