O2 sensors

O2 sensors
So, before I tackled the timing belt, etc, I had always had a check engine light on with the following codes:
P0036 Bank 1 sebsor 2 heater control circuit
P0141 Bank 1 sensor 2 heater control malfunction
P0175 P0175 system too rich bank 2
P0685 ECM/PCM power relay control ckt open
Then the first two codes repeat
P0036 Bank 1 sebsor 2 heater control circuit
P0141 Bank 1 sensor 2 heater control malfunction
So, I was able to get the firewall o2 sensor post cat replaced, cleared the codes, and now after a while of driving, I'm getting these
P0685 ECM/PCM power relay control ckt open
P0152 bank 2 sensor 1 high voltage
P2298 bank sensor out of range during deceleration
1st question, could my idle problem when cold cause the P0152, P2298 issue?
2nd, is the P0685 the whole ECM or is it related to the relay for it in the under-hood fuse box.?
so, just for kicks, last night i swapped the ECM relay with the rear defroster, will check later when I get out of work.
It's funny, my stock radio has been doing this funky think with the clock and station display not turning on until I turn the radio on since doing the timing belt job
Hmmm...

AAAHH?
I figured you would have posted any codes you had before the timing belt change.
I won't say this changes everything, but it may have an effect.
Bank 1 sensor 2 since you have a V6 I believe is the postcat 02 sensor on the bank of cylinders containing cylinder number one. No I don't know which one it is on the Honda engine. Seems you got that correct since the codes are gone. Bank 2 being rich, well, not changing either of the front O2 sensors and having the bank 2 Rich go away is unique.
However the other two new codes relating to bank 2 seem to indicate an electrical issue with the bank 2 sensors. I have never seen the ECM code before but I am far from the forum expert on The vue, let alone the Honda 3.5 L V6. I'll look up what the codes are and post the definitions later tonight and hopefully someone else on the forum can pick up from here. Otherwise I'm just guessing wildly.
