hello,my question is,on the heating circuit,does the computer sends a continuous ground that its always present until the engine shuts off or the ecm presents this ground only as needed? i ask this because i can splice a known good ground wire to the oxygen sensor heating element ground side thereby solving the lack of ground at the harness thanks alot !
-
Could you please double check the code, I have been trying to find more information, but the P0036 code is not listed in the factory service manual.
The ECM does not send the ground. The sensor gets the ground from the body ground and the ECM sends power.

I have a Pontiac g6 2008.today I was listen to some music.when I got back the car.the radio stop working.I replace the fuse and it still WOULDNT work.So I had Auto zone test it.and code p0036,p0056,po122,po141,po161,p0223 and it was saying my heater control circuit sensor bank 1&2 plus heater performance bank 1&2.and a high voltage.Please help me,I need to no what's wrong before I have to go back to work on Monday.

Did you had the codes (or engine light) before you replaced the fuse? Have you tried check the fuse installation? Start by checking all the fuses, and makes sure all the fuse are properly installed.
