Denso234-9014 Air Fuel Ratio Sensor

Please make sure your trim is a ULEV model before purchasing any of the other sensors for the 1998-2002 Honda Accords with an F23A1 engine. I first got the wrong upstream sensor, which it states it was for my engine, but not for ULEV. The confusing part is that ULEV uses the Air Fuel Ratio Sensor which is a completely different thing apparently. Another trick I found out, is to tell the difference between which sensor you need is on the exhaust manifold. If the sensor is on the side, pointing towards the passenger side, it's not the ULEV model. If it's at the center, it's ULEV.Once I used this sensor, everything works as it should and I no longer had the CEL come back on.

my ecl came on on my 2001 honda accord 4cyc ulev. Went to autozone to do a reading and it was P1167 which after thoroughly searching the internet, it was the front oxygen sensor. Some web sites say this part is not compatible (even amazon) while some say it is. Other side gives you the universal model and other brands. I was skeptical at first when ordering this, so all users here say this is the part I needed. Took my chance and it worked. Installation was a breeze (if you know what you are doing). I used a regular wrench to remove the old one and to tighten the new one. You can buy or go rent the special socket if you feel more comfortable with that. After taking off the old one, I applied the (included grease) onto the new one's threads and hand tighten first and then use the wrench and tighten just enough that there was a resistance. Turned my car on but the light was still there, even drive it around for a mile or two, but it was still on. Went back to research and lots of sites tell you to pull the battery or the back up fuse. DON'T DO IT!!!!!!!!!!!. All i did was turn my engine on, let it run for a minute, turn off, then let it rest for a minute or so. After the 5 time, i just let the car run and idle and the next time i know, the ecl went away. It has been a month since i replaced and drove a couple hundred miles already. ECL never came back, feel the car have power again and so far gas mileage is back to where it should been.

exact replacement for the OEM sensor that DENSO makes anyhow at an unbeatable price

Since I like reviews that simply focus on the facts instead of bias and opinion, I thought I would contribute by reviewing the way I would have found most helpful. My car’s check engine light went on so I plugged in my BlueDriver OBD2 interface and found that the error codes P1166 and P1167 had been generated. After researching/reading other people’s experience with these codes, I had found that my specific Honda is finicky when it comes to the brand of Air/Fuel ratio sensor used to resolve this problem. That being the case, I decided to go with Denso after learning that they made the original equipment part for Honda. I went to a local auto parts store and they wanted $230 for this sensor!!! I also checked rockauto.com in an effort to find the best price for this part but I decided to buy mine through Amazon to make certain that I was getting a genuine Denso part and because I have a prime account. When the part arrived (came with everything needed except the 7/8” box-end wrench), I installed the sensor using the included anti-seize and cleared the codes with my OBD2 interface. Everything worked beautifully and the car drives so much better now!--- PART INFORMATION ---Manufacturer: DensoDescription: Air/Fuel SensorPart Number: 234-9014UPC: 042511110465INCLUDED: Comes with anti-seize and instructionsNOTE: Color of 4-wire shielding is black and not green although worked perfectly on my ULEV AccordNOTE2: Honda info from original part was “DU2 DENSO 192400-1020 05D09 JAPAN”--- MY CAR INFORMATION ---Model Year: 2002Make: HondaModel: AccordTrim Level: EX-ULEVBody Type: 4 Door SedanEngine Type: L4, 2.3LEngine Code: G6Transmission: 4 Speed Automatic--- ERROR CODES ---CODE: P1166DEFINITION: A F Sensor Sensor 1 Heater Circuit MalfunctionCODE: P1167DEFINITION: A F Sensor Sensor 1 Heater System Malfunction

I installed this o2 sensor (it's actually an af sensor even though it says o2) on a 2001 honda accord with ultra low emissions, and it worked great, the check engine light is off!!! The only glitch was... I reset the computer by disconnecting the battery cable. This car has a theft system. Essentially the radio refused to work, asking for a radio code to be entered. I tried a few times until the radio locked me out. Just disconnect the battery cable again for a few minutes to get the radio to accept codes once again. I was able to go to [...] and use their data base with instructions on how to get the radio serial number with out removing it. After suppling vin, radio serial number, address and phone number, it gave me the correct code to unlock the radio. Follow the web site directions, assume you know nothing, read everything. You get three tries then it locks you out. I got it right on my third try...phew...I think if you don't disconnect the battery to reset the computer, the light will eventually shut off after a few engine cycles of driving for 15 minutes each time.
