What does OBD code P0427 mean on a 2012 Dodge Grand Caravan SE (flex fuel)?
Check engine light came on a couple days ago and I have a generic code reader and got a P0427 code. Surely there is a Guru out there that can help me get specific with this code and my vehicle type.
02 HEGO (heated exhaust gas oxygen) sensor(s) upstream. Change it / them after 80,000
