Hi Experts,
just recently installed OEM deal catalytic converter. after driving 30 mins. following 2 codes came up. P0301 and P0037.
P0037 :ho2s heater control circuit low bank 1 sensor 2
P0301 cilinder number 1 misfire.
where to locate Ho2s bank 1 sensor 2 ?
thanks

 

O2 sensors for both banks are located on the upstream (1) and downstream (2) sides of the cats, and in relatively close proximity to the cats.

Bank 1 is firewall, Bank 2 is core support.
