Thanks. I'm going to get the sensors out and run volt meter tests on sensor wire as well as heater circuit wire just to be sure they are okay or not. What is weird is that when I unplug the 4 sensors the codes go away 1 at a time... Does that make sense? Would the PCM just ditch the codes it...

May I ask why you replaced yours? I also have a manual 05.. And all at once I got O2 heater circuit voltage low codes... P 0031, P 0037, P 0051 & P 0057 I've replaced the upstream sensors recently due to codes a while ago which resolved that issue. I am going to test ohms and voltages on the O2...

Have you managed to resolve this in the long term? Was it bad wiring somewhere? I have the same issue and wiring all looks fine...

Hey Pullski. So I am getting these codes.. P 0031, P 0037, P 0051, P 0057 - is this bulletin to fix these issues?
