Both p0175 and p0151 code

Hi all,

Car has been sitting a few years with literally zero driving. Gas is a few years old. 155k miles.

Getting these codes after starting it up. How do I diagnose? I have a scanner with live data. Bad MAF?

If it was me I'd start with extracting the old gas and filling with new (I'd also do other fluids as well after that long). There's no way that gas is still good.

4 years old fuel is not the problem.
codes say b2s1 O2 sensor wire may be damage by rats and robo cat needed.

Well the wire seems okay… Should I try replacing the sensor?

I have careless headers FWIW.

Swap the sensors cable connectors and if the errors point to b1s1 then b2s1 is bad.

This is pre-cat codes so catless is not related.

From what I remember, all four sensor connectors are keyed. You would not be able to swap them around.

Hooked up the live data scanner and I was getting 0V to that sensor. Went ahead and ordered a new one. Fingers crossed

I didn't know this, as non-M cars the connectors are the same so they are swappable.
