Product Description

Sensors that measure Air/Fuel Ratios have highly sophisticated sensing elements, which allow them to create precise outputs in proportion to the ratio of Air/Fuel
This dual protection cover maintains the correct temperature to allow faster response times, as well as protecting the ceramic element against contamination.
A Denso oxygen sensor utilizes an aluminum oxide trap layer to prevent the ceramic from being contaminated by silicone and lead, which prevents the platinum electrode from being damaged.
With a corrosion-resistant housing and watertight body, this housing is resistant to contamination and corrosion
A porous PTFE filter makes it possible for atmospheric oxygen to enter the sensor without allowing water or contaminants to penetrate the casing
As a result, AFR Sensors provide the ECU with an Exact AFR Response, resulting in better performance, lower emissions, and more gas mileage.

Questions & Answers

The Highlander's O2 sensor is already there on the front. Would this sensor replace it?

Although I am not sure what the sensor is on your Highlander, it replaced the front sensor (just behind the radiator) in my 1999 V-Series There are six Camrys. I now don't have to worry about "Check Engine" warning lights!

How can I get sensor 1 bank 2 for my Lexus 2003 RX300?

Using this will solve all of your problems.

There is a P0155 code - Can you help? The sensor 2 for bank 2 of a Lexus rx300 is labelled 1. Are you able to change it?

There is no way to tell. The one I have is an ES300, but based on my confirmation, it should work. Located on the exhaust manifolds is a sensor that measures how much oxygen is present upstream. Each side has the same problem.

This 1999 Lexus RX300 is for sale I have a bank 1 sensor 1 on my network
4/5

I find it to be incredibly helpful! When I drove my 1999 Lexus RX300, I started getting CEL codes (P0125, P1030, P1033). The P1035 number. Denso 234-03 was located on ClubLexus, so an entry was made for it This sensor is the perfect match for Bank 1 Sensor 1, located behind the firewall and accessible from underneath the vehicle. Remove the connector first, as it is the most difficult task. A pick up tool with wire prongs was used to hold the sensor connector part from the top. The tab on the right connector was pressed and it was relatively easy to disconnect. After jacking up the passenger side of the vehicle, spraying PB blaster penetrating oil on the old sensor threads, letting it soak for a few minutes, and using an O2 sensor removal tool, I was able to push the sensor out. The antibacterial agent is applied Install the new sensor threads and the thread seize that was included with the package. We spent less than 30 minutes on the project! The codes came back after connecting the battery negative terminal for a few minutes, but when I started the engine, the codes went away! Visit the images section to see the pictures. This sensor is designed to work for Bank 1 Sensor 1 (before the catalytic converter, accessed underneath the vehicle) and Bank 2 Sensor 1 (between the engine and radiator, accessed from above). Item to note If working underneath the vehicle, it is recommended that you use two jack stands for increased safety. A copy of the PB Blaster is available here. In addition,.

Six thousand miles later, the sensor failed
5/5

Includes an updated review of the "holy moly" series. The sensor was professionally installed after I bought it from Denso. While I did purchase the part quite some time ago, I have only driven a little over 6,000 miles (and I have proof of that), and now my check engine light has come A diagnostic shows that the same sensor needs to be replaced once There seems to be a misconception that sensors should last more than a year. My attempt to contact Amazon regarding its warranty on the part was unsuccessful. They did respond and asked for more specific order info, which I have since emailed to There have been more than 4 days since the order info was sent to them, yet they have not replied. My warranty issue can be contacted directly with Denso and every time I press the button Mary, in the warranty department, is not available. It has been 10 days since I left 3 messages for her and I have not yet received a call back. As a result, I sent an email to Denso requesting information on warranty. The warranty information has only been emailed to me since yesterday, and I am hopeful that I will get it tomorrow. Then there's the fact that I can't drive my car as there is a check engine light and I don't want to risk more damage or damage to my How can I get warranty information so difficult? I'm not sure why it's so hard. The hassle I'm going to have just trying to get the insurance number has been immense. I can't even imagine how hard it will be to get them to honor my warranty if it's still valid. However, the cost of the sensor was quite high. As far as Amazon is concerned, it is still my favorite. A revised review has been posted. It was still a bit early to hear about warranty when I saw something that made me melt. I was placing orders for other items and confirming delivery dates when it suddenly hit me. In one of my packages that was en route, I noticed an Amazon delivery lady had included a brand new sensor absolutely FREE of charge. Even though I had to triple-check it, I almost couldn't believe what my eyes were seeing. My excitement and appreciation were over the fact that Amazon made good on its warranty for the product even though I purchased it two years As you can tell, it only lasted 6,000 miles, so they could surely tell that it was defective. The customer service they provided went far beyond my expectations and I am forever grateful to them. I would not have had access to a vehicle for who knows how long if that had not been done by Amazon -- I am disabled and on a fixed income, and couldn't afford to replace the sensor at that time. Due to Amazon, I have now been able to get back on the road after I did the DIY thing. Amazon, thank you so much!.

An expert at Denso says that the 234-point range was found to be the best There is a telephone number 9007
5/5

An expert at Denso says that the 234-point range was found to be the best Two of the 9007 code are 234-6 A sensor 9009 is identical to a sensor 9009, but their wire lengths differ. There are two parts to the 234-page report The model 9009 comes with 14" leads and a 234-foot main cable The lead length of the 9007 is 11". There are many Toyota applications (California certified vehicles) in which these sensors are used for B1S1 and B2S1, and, in so far as attention is paid to lead dress away from the hot manifold, they can be used interchangeably. In order to replace B1S1, it is imperative that you have the proper tool because the space between the firewall and the engine is so tight and it will take a great deal of force to twist it out of the manifold. If you need a tool in the Midwest, Advance Auto Parts will lend you one or sell you one for less than A slot is cut into the tool so the wire harness can be cleared. It is similar to a closed end wrench. I wish long life to the Gen 1 Toyota Avalon.
