How do I fix these sensors?
 
My car showed these 4 error codes:

P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)
P0160 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
P1178 O2 Sensor Signal Circuit Slow Switching from Rich to Lean (Bank 1 Sensor 1)





So I'm guess I need to replace "Bank 1, Sensor 1", and "Bank 2, Sensor 2"?


Where are these sensors? How much am I looking at? Is it hard to DIY?

Please and Thank you!

four o2 sensors for a start/

Bank 1 refers to the first three cylinders and sensor 1 means the pre cat sensor. According to the codes you have, you have an issue with the pre cat sensor of bank 1 and the post cat sensor of bank 2. Changing the sensors is a really easy job and as far as price goes, both sensors are the same and about 160$. Good luck

thank you very much for that information.

I will need to get that fixed...

OR you could simply just purchase a bfh and that would fix your problem

whats a bfh?

I bet you are getting worse mileage. They should improve that.

oh... ok..

also, your rear 2 o2 sensors dont do anything other than tell the ECU that the cat is working. If you can deal with the cel, forget about them.

I say change them all better milage no cel and no worries...if the cel stays on then you will have to scan often to make sure it's the same prob. another thing the car will stay in limp mode so do it.

I'm sure you can get used ones if you dont have the cash for it new but dont leave that like that.

just my opinion...

anyone know if a 318 and a 328 use interchangeable o2 sensors?

morpheus 09-27-2009 05:02 AM

Not interchangeable. Post cat and pre cat sensors are different from one another and are cheaper than the 328 ones.

No, but there is some way to use 325 sensors. You just have to change the wiring, and they are half the price!

Wrong answer. The 325 sensors are voltage. 328 is impedence or some shit. Different technology
