Cel code: H02S12
Definition
Heated oxygen sensor - bank 1 sensor 2 (HO2S12) circuit fault *P0136*
Probable cause:
- Open or short circuit condition
- Poor electrical connection
- Engine mechanical fault
- EFI relay fault
- Faulty heated oxygen sensor - bank 1 sensor 2
Just got this code on the way home tonight coming from the bank. It's on the 96 I recently just purchased 5VZFE. Before I go into searching for the exact culprit does anyone have experience with this code and how did you fix it.
Thanks in advance,
TFJ

Pretty sure I found what I need but any input is still welcomed.
