P0134: HO2S Circuit Insufficient Activity Bank 1 Sensor 1
P0154: HO2S Circuit Insufficient Activity Bank 2 Sensor 1
P0155: HO2S Heater Circuit Bank 2 Sensor 1

i'm not 100% sure but my guess is that those codes are telling me 1 of 2 things probably, either both my O2's are shot or my extensions are faulty, the extensions worked before the H/C swap so see below...

my narrowed down guess would be the O2's are shot and i think the culprit might have been from burning off the excess coolant after i did the H/C swap?! any ideas about that?

also what does CKT mean, circuit?
Bank 1 is drivers side and Bank 2 is passenger side??

thanks

 

ok found out the front O2's are dead

anyone know the part numbers off hand for them?

 

well after using the awesome search feature at the top of the page, i managed to answer my own questions from this thread
