I was mildly intimidated at first till I realized they were all o2 related. Just hoping for a "this was my problem for the same codes" before I dig in.yikes, Thts a decent list. Hopefully someone here can help you out man
Ho2 circuit was open. Disconnected the o2 sensor and checked continuity of with Ho2 circuit wires. It appears both wires for the Ho2 are broken some place. Heater circuit power and ground are intact. Shiukd be fun to find and fix or pull new wire. Either way its gonna stink.Check fuses for both O2 sensors first.
