Two Engine codes, confused.
Two Engine codes, confused. My car is throwing two codes, i replaced both of the 02 sensors at different times, i replaced the last first one in february and i replaced bank 1 2 days ago.
P0153 02 Sensor Circuit Slow Response (Bank 2 Sensor 1) this code
and this one P1153 Ho2s Insufficient switching bank 2 seonsor 1
what could this be since i replaced both 02 sensor recently

haha had the same problem look at your fuses i spent money on o2 sensors and that didn't fix it i was told to get a new mass air flow so i did that and it didn't do **** so i was told i needed a new computer but i looked at my fuses and i had one that was burned out and it fixed it i wish i know that before i spent all that money on o2 and mass air
if i remember right its a 10 or 15

It sounds like you might because that can make both banks run rich and screw with the O2 readings. It can also cover them in black soot which will slow their reading (insufficient switching)

Check by sight and if you don't find anything use a piece of tubing and run it around the intake etc... alternatively you can use carb cleaner or something similar just spray a little and if the engine stumbles you found your leak.
