Took it to advance auto to have it read. They said both rear o2's are out and one of the fronts too. I have had o2 sims in the rears for about a month now and never set a code before. Is it possible that the diagnostics just saw the sims and figured they weren't working? Maybe just the front? This is what the readout says. I have no idea what it means. Any Ideas?

what does the o2 heater circuit malfunction mean?

 

Don't know the answer but your not throwing codes for post cat 02's so the sims are working. I think the bottom description for slow response on Bank 2, Sensor 1 should read P0153? If so, you have current codes for both front 02s.

 

your right po153 for the later....
