Emission Warranty Extension: MIL Is On With DTC P0420 or P0430
(Vehicles Currently Registered in 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 to 17 years from the original
date of purchase. The mileage limit is unlimited for the first year of this warranty extension based on the campaign launch
date.
After the first year, the warranty coverage is 17 years from the original date of purchase or 200,000 miles, whichever comes first.
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.
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.
What to do if you feel this notice is in error

If this is not the case, or the name/address information is not correct, please fill out and return the enclosed, postage-paid

reimbursement, even if you no longer own the vehicle. Refer to the attached Instructions for Reimbursement form
for eligibility requirements and the reimbursement procedure.
