I have an issue with these two codes (P0051-P0301).
First some catch up on what I've done thus far: Replaced the head gasket and all seals from the head gasket up in 2015. (Re-replaced the head gasket this year). Replaced all the plug wires and plugs when I did the head gasket. I've replaced both upstream and downstream O2 sensors. I have done a compression check and that's good. I've also done a engine block test and that's good as well. I am trying to get the state inspection but keep getting codes P0051 (HO2S heater control circuit low (bank 2, sensor 1), and code P0301 (Cylinder 1 misfire detected). I have rechecked everything and am running out of ideas of things to check. Any help would be fantastic. Thanks everyone.
Also, I got the T/C and ABS lights which told me that my right rear wheel speed sensor was bad. I replaced all four sensors but can't get the lights to go off. Any ideas on how to reset these codes?
