I had a diagnostic done and it came up with po 133 bank 1 sensor 1 o2 sensor slow response; po153-bank 2 sensor 1 o2 sensor slow response; po171B-bank 1 too lean; po174B-bank too lean. The garage wanted to charge me $ 350 a piece for the sensors plus about 1000 in labor because they said it was hard to get to the sensors. I have seen sensors online for 40 dollars. What type of 02 sensor do I need? 1, 2 or 3 wire? It should NOT cost this much for 02 sensors should it?
