I have a P0038 code on 2007 Nitro, 3.7 eng. is there a fuse for the 02 sensors on this make?

Question

I have replaced all 4 of the 02 sensors on ,my 07 Nitro, 3.7ltr. put the CEL out, stayed off for about 5 minutes and came back on with the same (2) codes

I have erased the codes with a scanner, CEL still on, Have disconnected the -battery cable for over an hour, CEL still on. I have replaced all the o2 sensors front and back on the exhaust system. Have checked the connection's all are tight. The code P0038 is for Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2. Is there a fuse for these sensors? Some post say there is some not, I can't find anything in the owners manual on this. I have checked for pinched or burned wiring from the connection to the firewall. Everything looks good.

There is no fuse for this, What you have encounter is a PCM or PCM software issue to correct this you will need a Reprogram of the PCM. Here is a TSB # 18-051-11. title Engine control - Avoid multiple DTC software update
