Selected User Reviews For Denso 234-9042 Air Fuel Ratio Sensor

By replacing this sensor myself, I was able to save several hundred dollars
5/5

For my 2002 Camry V6 3. 0, I purchased a Denso Air Ratio sensor. The Check Engine light was illuminated on a 0 litre engine. P1155 indicated a bad air/fuel sensor Bank 2 Sensor 1 according to a free scan performed by a local auto parts store. This can be found just below the air intake on the intake side of the manifold (front right). A O2 socket was also on my list of things to order. I was able to quickly remove the old sensor after spraying it with a penetrating oil. Disconnecting the wiring harness took a little longer for me. The copper anti-seize paste was applied to the new Denso sensor (234-1). 9042), and then followed the steps below to clear the code. By replacing this sensor myself, I was able to save at least $200. Before ordering the new sensor, I forgot to test the two black heater wires on the old one. Set your ohm meter to 200 ohms and any reading less than 2 ohms is a false positive. The sensor is bad if it has a rating of 5. If you buy a Bosch or a less expensive sensor instead of a Denso, the problem will persist, according to other reviewers. br>br>How to turn off the check engine light: Turn the key to the on position. br>br> br>Check to see if the odometer reading is visible. br>Return the key to its original position. br>Push and hold the trip odometer reset button. br>Continue to depress the reset button while turning the key back to the "on" position, but not far enough to "start" the engine.

If you own a Camry, this is the one to get
5/5

On my 2002 Toyota Camry, the check engine light was illuminated. Purchased a less expensive sensor in an attempt to save money. I got the same check engine light and error code. I spent hundreds of dollars and had the car serviced by four different mechanics. Everyone said the sensor was the problem, but three of them said the sensor was fine. I finally spent the money on this Denso sensor after finding two websites that said only Denso or Toyota sensors should be used. The only issue I had was the wire was about two or three inches shorter than the stock wire hold down, so I couldn't use the stock wire hold down. . . You will not save money by buying the cheaper sensor. . . You will only have more mechanics bills and who knows what kind of damage you may do to your engine. . . The only issue I had was the wire was about two or three inches shorter than the stock wire hold down, so you will have more mechanics bills and who knows what kind of damage you may do to your engine. However, I'll take it because it solved my issue!.

O2 Sensor Bank 1/Sensor1 for the 2010 Lexus RX350 It was a perfect match
5/5

It's a pain to put in because it's installed before the CAT and the car must be jacked up. It should take a mechanic about 30 minutes to complete. 45 mins. br>br>Note: If you're looking for a unique way to express yourself, try using the words "creative Bank 1/Sensor1 is FRONT/RIGHTbr>br>It's also for the 2010 Lexus rx350, which was released in February 2010. So, what exactly does this imply? So you examine the letter following the fourth digit of your VIN. It must be at least a B. B stands for February, and C stands for March. Any previous grades, such as an A-, will not be accepted. It's a different section of the building.

For the 2007 RX 350 bank 2 sensor 1, it falls short by 56 inches
3/5

[Additional Note 1/5/19] Should have stated that this was used to replace the A/F sensor in the 2007 RX350 Bank 2 Sensor. br>br>I thought this was a great match, especially since both Amazon and Google said "match. " It's about 5 to 6 inches too short, which is a pity. Unfortunately, after comparing only wire color and shape, I cut the wire too quickly. To make it work, I had to repurpose the old wires and cover them with black tape. After all the extra work, I'm not sure the $50 savings is worth it. It's possible that I ordered the wrong part; it's a good idea to double-check everything before proceeding with the installation. br>br>After clearing the CEL/VSC code, the sensor worked fine.

For a 2007 Lexus RX 350, this is the perfect OE replacement: Sensor 1 (Bank 1) The 2007 Lexus RX-450h is a perfect match

Sensor for 350 ppm of oxygen Bank 1, Sensor 1, which has to be accessed from underneath the car, on the firewall side, upstream from the catalystic converter! It unquestionably necessitates the use of the unique open-source software. deep on one side- To remove the socket, press the button on the right-hand side of the socket. without causing any harm The majority of the O2 sensors in my Lexus and Toyota vehicles could be replaced with open-source alternatives. end or box-shaped the final nut However, I couldn't get a standard wrench into the space where Bank 1 Sensor 1 is located, and I couldn't get any leverage on a standard wrench in such a tight spot.

Original equipment manufacturer (OEM)
5/5

If your application requires Denso, use only Denso, which can cost up to $275 at a dealership. It worked perfectly, and the code vanished; I'm glad I found it here.

On a 2004 Toyota Sienna, the upstream air/fuel ratio oxygen sensor needed to be replaced exactly
5/5

The original sensor was covered in a white coating that had worn away, resulting in a lean fuel/air ratio. The central electrode isolators on the spark plugs were almost white, and the engine hesitated when accelerating. Now the engine responds quickly to accelerator input and runs smoothly. The unit was a perfect replacement, right down to the clip securing the wires on the bracket to prevent chafing. I would purchase this item again.
