🔬 Denso 234-4620 Oxygen Sensor: Precise Air/Fuel Monitoring for Enhanced Engine Performance Review

2 stars. "I have shaky confidence. I'm pretty sure I got the previously installed item. The product had discoloration on the tip, dirt on the stopper, was not in a plastic bag and was not the wrong size tube. I installed it anyway and it seems to work. I didn't have a comparison until the bottom gauge arrived. If I had bought from a local store I would have returned.

Works on my 96 Accord LX. Plug and Play.Check Engine Lite reverts back to normal after restarting the computer (I pulled the fuse out of the box to do this for web searching). Note. For SMOG: If you restart your computer, you have to drive about 100 miles before you can pass SMOG. I failed the first time because "OBD System Checker" ran out of memory. I drove the car about 100 miles or so, came back and it was gone. I hope that this information will be useful to someone.

Fixed my gross idle and check engine light on a 1997 Accord. The wire is slightly longer than standard (maybe 1 inch) and fits perfectly. If you use a misaligned oxygen sensor shorting bushing, it will hit the heat shield. I had to remove the exhaust heat shield to get the old sensor out and this is the new one. If you use a tool with a longer head it will work just fine, but I didn't have one. This sensor looks almost exactly like the original. I will update when the mpg improves.

This was the correct part for my 2001 Honda Accord VTEC F23A1 4 Cylinder Engine. It came with a white plastic protective sleeve inside the connector. The instructions don't mention this. I had to remove the white plastic cover with needle nose pliers before the plug could be inserted into the socket. I also had to remove the old neoprene gasket that was left in the socket when I unplugged the old plug. A bit of trial and error, but worth it. Pulling and reinserting the 7.5Amp "Clock Back Up"…

If you are getting codes P1166 Mass Air Flow Sensor Bank 1 and P1167 Sensor 1 Heater you will need a Denso Air Fuel Ratio Sensor 234-9014. This is the top sensor. The 2002 Accord does not use a traditional O2 sensor but uses a fuel ratio sensor. What to look for and what is very important (1) Motor type, mine is F23A4 which can be found on the side panel of the motor on the drive side. (2) Take out the original sensor and you will see the model on my Densor 192400-1020 is Denso 234-9014. For…

I would give 5 if it wasn't for the free shipping. This is perfect for my 2000 Honda Accord LEV (NOT ULEV again). ULEV is three times more expensive than LEV, as noted by other reviewers. DO NOT CHANGE parts - that's why I had to deal with some people who left negative reviews. The ULEV-O2 cables are longer than the LEV-O2 connection cables. I've visited this site several times and wasn't sure. I had to read all the reviews before realizing that there are really 2 different oxygen sensors for…
