Good Evening Everyone!

After all these years, I finally got an check engine light.

Codes are P2259 and P0037.

Already have the air valve/solenoid and the rear/downstream 02 Oxygen Sensor on order due to the codes.

My questions is, do I really need a special socket to get the rear 02 sensor off? If so, does this work:

If I don't really need that 02 socket wrench (mentioned above), can I use a regular wrench? I'm assuming 22mm will work?

Thanks and any other useful information/knowledge is greatly appreciated.

 

Some times they can be a bitch to get off. I have an O2 socket but most of the times I just use a 22mm box end wrench.

 

Just and FYI, I got the rear 02 Sensor off fairly easy. It was harder to move that damn guard from around it due to the bolts being rusted and couldnt remove it.

 

IIrc, a 1" wrench works also.

 

What size socket is recommended for the upstream o2?

 

I Believe it's a 22mm as well. Same as back o2.
