I have a 1998 4 cyl EX that says it's CARB certified for Ultra Low Emissions, so it looks like it's a ULEV then right?
The O2 sensor is in a pretty easy to access place right on the front of the exhaust manifold. Will i need any special tools to change it out?

I think it has to be a ULEV engine because P1166 & P1167 are error codes that only exist for the ULEV engine.
Sometimes you can get the O2 sensor out with normal tools. Old one is scrap, so you can cut off the wire. Forget what size socket, maybe 22mm?? The heat-shield probably get in the way, so see if that comes off without too much persuasion (corrosion).
There's a special socket, but really the only thing special is it's got a slot for the wire. So if you can get the old one out with a socket (cutting the wire) then put the new one in with an open-end wrench. Don't need so much torque to put in the new one.
Or borrow the special socket from AutoZone or someplace like that.

So, I'm in the same boat as imweeks.
It was throwing P1166 and P1167, I read a lot online and decided to buy and install the Denso 234-9014 sensor for the ULEV engine (since that what I have). A whole bunch of people said that it was the right sensor and would definitely fix the problem.
Before buying it I visually checked all of the wiring (as best as I could) and the fuses. Everything seemed okay.
I just got finished installing the sensor, I cleared the codes, and right away it threw the P1167 code again. ?!?!?!?!?
I'm going to recheck all of the wiring, check everything with my multimeter, and I'll let you know what I'm getting, but boy is this frustrating. If anyone has any thoughts or ideas about what might be wrong, please let me know!

Nice catch!
I used to have a 1998 4-cyl non-ULEV. Having looked through the wiring drawings, I know the wideband O2 sensor was powered from somewhere different on the ULEV engine, but I didn't remember WHERE they got the power.
