P0030 code which sensor to check? Help!

[Bmaughan]

Hey so I threw a p0030 code the other day. O2 Heater circuit failure. Cleared it and checked for 12v to sensors. All seems well but it threw the light again.

So I’m pretty confident i need to replace a o2 sensor. Question is: which one? Anyone run into this problem? How am I able to determine?

I’ve read somewhere that p0030 is bank one upstream... I’m assuming that’s pre cat but which side is bank one?

any help would be seriously appreciated!

Bank one is passenger side. Try swapping your o2 sensors around to see if it changes anything before spending money on a new one.

that’s a good idea... can you confirm that p0030 is in fact bank one?

Yeah looks like it.

Id check your connections and try swapping the sensors before anything else
