2004 h2

Proud owner of a brand spanking new (new to me) 2004 H2!!

Purchased it last night and now the check engine light is on
The guys at AutoZone say it's an O2 sensor. Any idea on how to swap these buggers out?
I tried searching but no clear instructions.. any help would be greatly appreciated.

O2 sensors are pretty easy. You just get under the truck and you can see them on the down pipe. You unscrew it with a 22mm (right?) end wrench and unplug it from the pigtail. Then screw the new one in and plug it into the pigtail. Should be easy on an H2 since you have so much ground clearance.

Welcome, that's a nice looking 2.

Thanks for the info. I'll be taking a look under there shortly.

I plan on taking off the ugly running bars as well.

Yes, I bought a code reader on Amazon and got everything figured out. Thanks!
