2001 Dakota 4.7 with A/C. One 02 sensor went out so I replaced them all. Now getting a Code: P0051 H02S Sensor Control Circuit Low (Bank 2 Sensor 1)
When driving with scanner on here is the data
Oxy Sensor 2 Bank 1 .660 V (some fluctuations)
Oxy Sensor 1 Bank 2 1.000 V (no fluctuations)
Oxy Sensor 1 Bank 1 .660 V (some fluctuations)
Oxy Sensor 2 Bank 2 .660 V (some fluctuations)
I have replaced Oxy Sensor 1 bank 2 twice now with factory parts and still throw the code.
question: is it possible my 02 Sensor Relay is going bad or is there a fuse somewhere that could be bad?
