2009 Kia Sedona with engine code P0051, P2195 and P2270. Can all three sensors be bad?

Question

I have a 2009 Kia Sedona 3.8L. The check engine light came on. I have a code reader.3 codes come up a P0051, P2195 and P2270. Can all three sensors be bad? Could the fuse be bad if so where is the fuse located? What are the part numbers for the 3 sensors? Where are the sensors located?

Answer 1

P0051 H02S Bank 2 Sensor 1 heater resistance

P2195 H02S sensor stuck lean Bank 1 Sensor 1

P2270 H02S sensor signal stuck lean Bank 1 Sensor 2

With all 3 code reporting a lean condition, this may not be the H02S sensor but a running lean condition of the engine. There is no fuse for the H02S sensor. You can subsitute a know good MAF (mass airflow sensor) and retest the system for a lean code symptom
