Which O2 sensor do I need to buy?
My 2004 TL has codes P0135(O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
) and P0155(O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1) ). I understand its 4 sensors total so Im assuming I only need to replace 2. But which 2 are these? front,rear,downstream,upstream?? im clueless and I just want to make sure I order the right one.

No need to post the same thing twice in two different sub-forums.
If you posted one in the wrong place by mistake, just PM a mod and ask 'em to move it for you.
Moved the response you had to the other thread.
