i got that code autozone said o2 sensor heater, circuit malfunction (bank 1, sensor 1)

i got bosch 13354 and replaced the one in front.

now i am wondering was that the correct one?

the guy donw there said it was but i dont trust them.

I think you may have needed an A/F ratio sensor which is like an oxygen sensor but a lot more expensive.

well 122. each for them, not expensive engouh?

well i finally went and replaced both the back one had gotten into an aruge ment with the exhaust manifold and meilted the connector. that was my problem.

another question there is a sensor on top of the power steering pulley assembily. how important is that?

what would happen if if broke and was not fixed?

There are 2 sensors pre-cat, which one did you replace?
