I found a generic 4 wire sensor from Bosch at Auto Zone. Bosch #15717. Spliced it in, reset the check engine light and it fixed the problem."

Thanks Bryang for your response. I posted on the brickboard

specificaly NOx. I pulled two codes out of socket 2, 435 which
is oxygen sensor slow to respond. Problem is, it has two so how
do I know which one is slow? The other code is 443 and using this
table here:
