Denso 234-4621 Oxygen Sensor

Fixed my 02 accord check engine problem. Should only take about 10 to 15 minutes job if you have a 22m o2 sensor socket. The hardest is the unhooking the clip.

Does Exactly What It's Supposed ToNo complaints here—this product works exactly as expected. It arrived on time, in good condition, and performed its intended function without any issues. Reliable and as described. Would purchase again if needed.

OEM fit for my 2002 Honda Accord for a fraction of the price. Great product.

Good quality, but time will tell

Wow, just wow. This product just saved my car.First off, I am a 24 year old woman who know absolutely nothing about cars. But I was pretty adamant about fixing my own vehicle. Especially knowing that I was not going to pay someone else to do an easy job. After countless research I came across this product on Amazon. This Denso 234-4621 Oxygen Sensor is described to be a exact fit on my car. I've come to learn that it's best to get the exact fit rather than universal oxygen sensors. My car is a 2001 Honda Accord, V4 EX 2.3 F23A4 Engine . It is ULEV which stands for Ultra-Low Emission Vehicle and means that the car emit cleaner emissions.My car was diagnosed with a Check Engine Light unfortunately after getting a new transmission. Using my Veepeek OBD2 Code Reader, I received the code of P0141 "O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)." If you're interested in the code reader, I will link it below. My 2001 Honda Accord has TWO sensors. I made the mistake of not realizing what this code meant. The code was for the oxygen sensor located UNDERNEATH my car where the catalytic converter was, and not the one located underneath my HOOD in front of the catalytic converter. If you're interested in the oxygen sensor underneath the hood known as an "upstream" sensor, you are looking for a Denso 234-9014 Air Fuel Ratio Sensor which you can also purchase on Amazon. So just to make sure this makes sense, Denso 234-4621, a downstream sensor (the product being reviewed) is what you're looking for if you're receiving the P0141 Code and it is UNDERNEATH your car where the catalytic converter is located. The Denso 234-9014 is an upstream sensor that is located in front of your catalytic converter underneath your HOOD. Even though I was mistaken on which sensors I needed, turned out I still needed a new Denso 234-9014 upstream sensor due to mine being oxidized after pulling it out.Anyways, I bought a 2 different things to work on my car: Stanley 91-929 3/8-Inch Drive Pear Head Quick Release Ratchet & RamPro 3 Piece Oxygen Sensor Kit. I will link the products below. Anyways, you want to go underneath your car to where your catalytic converter is. Using the RampPro Oxygen Sensor Kit, you insert the oxygen sensor socket where your sensors are in the catalytic converter, and use the 3/8" ratchet to tug and release the bad sensor. Just replace it with the new sensor and screw it on tight with the ratchet. And wolah! These two products worked perfect on my vehicle, and after replacing both of my oxygen sensors, I used my Veekpeek Code reader to erase the code! My car is now Check Engine Light free! Please do your research before purchasing any of these products mentioned in the review. And safety first! Please don't try to attempt to work on your vehicle without knowing the risks. This review is solely meant to indicate that this is the proper sensor for your vehicle if it is the correct year, make, model, engine, and ULEV. I hope this review helps someone out there. I will link the products I purchased to erase my check engine light for good below.Veepeek OB2 Code Readerhttps://www.amazon.com/gp/product/B01I8UJ0V8/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1Denso 234-9014 Air Fuel Ratio Sensor (Upstream)https://www.amazon.com/gp/product/B000C5UFW6/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1Stanley 91-929 3/8-Inch Drive Pear Head Quick Release Ratchethttps://www.amazon.com/gp/product/B000NJ63UY/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1RamPro 3 Piece 3/8 & ½” Drive O2 Oxygen Sensor Wrench Socket Tool Set – 1 Vacuum Switch Socket & 2 Puller Sockets Kit – Universal 7/8” / 22mm Professional Grade Removal Tool for Cars & Automotivehttps://www.amazon.com/gp/product/B01IAH7MSC/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Clear the oxygen sensor code on honda accord

Installed on a 2002 Honda Accord 3.0 with no problem.

The O2 sensor was faulty. I returned it. Bought the exact one at Autozone and it worked fine. Sad thing is I had a great price on Amazon and the Autozone one was $30 higher.
