P0156 code

[TM98]

I’ve just started getting the p0156 code. I haven’t seen that code very often when doing a search. From what it looks like it’s the O2 sensor bank 2 sensor 2.

I got the code and had it on for about two days then I cleared it just to see if it came back. After a day of driving it it came back on then about a day later it went out. I looked at the fuses under the hood and looked at the wiring and all look good.

Does it seem like it could be anything else or just the O2 sensor?

If you do not trust your computer, try swapping the downstream O2 sensors and see if the corresponding code for the other side comes up.
