Installation Notes and Tips

Verify connector style, terminal layout, and port count against the original valve before installation. Confirm the vehicle build date on 2012 INFINITI M35h applications, since fitment is split between vehicles built from 12/11 and to 12/11. After installation, clear diagnostic trouble codes and recheck EVAP system operation.
