OK so I've got a slight problem that I need so assistance with. Recently I aquired a 2000 Honda Accord SE w/ F23A4 ULEV for next to nothing because the auto trans was fark'd up. I had the trans rebuilt... which wasn't cheap and the shop that did it had to have the local Honda dealership re-flash the ecu for some reason (it was never explain to me why). About a day after the CEL came on so I have it checked and it turned out to be the front O2 sensor had gone bad. So after doing some searching to replace it I find that it's nearly $200 for the sensor. I looked over @ ebay and they've got O2 sensors for $50 but they are for the 2.3 DE, LX, and EX models. So my question is... will one of those sensors work for my 2.3 ULEV (POS)....

Thanks in advance.

 

thats a god question,but to answer i think you would have to wire it up to work.

 

As far as I know (and I'm pretty sure this is correct), both O2 sensors are 4 wire, 4 wire prong connectors, and even the wires are the same color code... I just wonder how different the ULEV spec on the O2S is over the normal F23 O2S.

 

The O2 sensor may be the same for the same year 4 cylinder motor. At Slhonda,
the part number comes up the same for the ULEV and several different models:

My understanding is the ULEV has the more expensive and sensitive sensors, enjoy that =p. I wouldn't mess with anything but OEM, especially on a ULEV car.

 

I just checked again at Majestic Honda, and the ULEV model does come up with the different number for the front O2 sensor.

The rear O2 sensor number seems the same.

In the stickies post above, it does says that non-OEM sensors may still trigger a CEL, on the ULEV.
