O2 sensor q's

[DueceMcCracken]

So I rebuilt the top end of the ti. Valve job, cleaning, resurfacing, new hg and gaskets. New cabin air filters, one new o2 senor, the first one. I keep coming up with two different obd2 codes. One is a generic code for the heater circuit on bank 1 sensor 2 then the other code is a p1186 for the same thing, lol, kinda redundant.

So Should I just be swapping out the 2nd o2 sensor or is there some relay or something I should be checking?

I will be checking anything electrical the bentley manual guides me through.

Suggestions?

I had to look up the second code online, I thought it was going to be something catastrophic, then I laughed because it was the same code I already had just the dealer code.

IIRC Bank 1 sensor 2 is the post-cat sensor. I had the same code, replaced sensors, problem solved. I will say however, I tried to use a Bosch universal sensor prior to purchasing the Bosch OEM sensors and it gave me the same code so don't bother with the universals, they're a waste of money.
