Hey guys, im new and i just joined. i need help please. i get the p0135 error that read: "o2 sensor heater circuit malfunction [bank 1 sensor 1] please help me locate this and troubleshoot it? i thank you all in advance.

 

It basically means your upstream oxygen sensor heater element took a dump. Order a new Denso sensor and replace. You will have to remove the battery, the battery tray, and the two part heat shield to get to it. I got the same code earlier this year, look through my post for the part number. https://acurazine.com/forums/1g-tl-problems-fixes-118/p0135-f-sensor-malfunction-877913/

 

I will report back as soon as I get this handled. Thanks again!

 

I have the same code on mine too. I will replace that when i do the valve cover gasket and spark plug tube seals

 

That could be the reason why your car hasn't been running correctly! My transmission was shifting very hard when I had that code...

 

really? my shifts like dook, and i haz that codez too!!!! DERPin it up over here haha.....guess i better head to town and rent an o2 tool.
