So i went to autozone and got these 2 codes p114b and p114d, are those my o2 pre catalylic and after catalylic? im trying to order these two sensors from Amazon and i need to know if they would fit like oem.
One is Bosch 17102 and the other is Bosch 17098. thanks

Is the car running ok? I would look into that a little more before replacing 2 o2 sensors. I think it would be rare for 2 to fail at the same time.

Looks like they are probably both for post catalyst bank 1.

thanks for replying, i did a couple of WOT to get some datalogs, parked my car for a few hours, then went to drive my car, that's when i got SES light and car was sputtering but it drives. got a few codes 2FD2, C7E2 and C2C2 from the JB4 usb but couldnt find out what is it, also noticed my RPM is not always at 600, sometimes it stay at 800 when at idle, never happen before. went to advanceauto and got these codes P114b and P114d. been doing research all day and i figured it might be the o2 sensors but im not positive. any help would be appreciated.
