P1151 is Right Upstream O2 sensor not switching. P0161 is related to the Left Downstream O2 sensor heater. P0156 is related to the Left Downstream O2 sensor voltage being low. You at least have a bad or aged Right upstream and possibly a wiring issue with the Let downstream O2 sensor, which you replaced.

Re: 02 sensors help

I posted a link of ALL of the OBD codes that you would possibly get from P1000 on up. I know there are more and I will eventually get around to finding them and adding them.
