about 02 sensors and whatnot
Hi,
it is important to get an exact OEM sensor with the exact plug type.
period.
I previously wrote you can get away with something different, but what can happen is short term trim will
work to keep everything in spec, and as long term trim is recalculated, LT will eventually complain that it is
sick of seeing all the out of spec signals.
so you can reset the ecu and drive for a tank or two and everything fine, but then you will get another
code likely p0171, p1130 and p1133 which is signal out of range
stick with dealer parts.

Hey there. New to this, but it looks like a great forum. My 2000 4Runner popped up a CEL right about 45k miles. Is that an automated thing? Don't seem to have any issues with how the engine is running, so I'd love to reset it if that's possible. Fuel mileage MAY have declined about the same time, but can't honestly remember. Bought this baby 14 mos ago on Ebay with only 35k mi. It was owned by a guy who lived in Manhattan and kept it in a parking garage. Almost like a time capsule, except for the dog hair.

have a 2000 4runner v6 with cali emission. had code 420 so finally replaced the front O2 sensor with a denso that I had to splice to old connector. Since I did this I get a surging when I accelerate only. It idles fine and once you get to speed it does fine. I disconnected the sensor before leaving work and the surging is gone. Any ideas out there? How can I test the sensor to see if its working correctly. This is really starting to pi$$ me off!!!!

Thanks! So you're saying I can't replace it? My mechanic said "drop it off for the day", but didn't say anything about the AFR sensor. The way he was talking, it was going to be easy for him to fix, so I assumed it was an engineered CEL that just needs reset.

My CEL came on and I went to Advanced Auto to get the code pulled. They told me the O2 sensor was bad so I bought the plug-n-play Bosch for around $125. I got home and checked on yotatech to see how much of a pita it would be to replace and learned that the Bosch sensors were NFG. So I never installed it. I found the Denso model locally for $103. Luckily, I got my money back for the Bosch. Here is a photo of the three sensors. As you can see, the Bosch is a different design and is probably a generic O2.
