I prefer Denso because the original equipment O2 Sensors that came with my 2004 Jeep Grand Cherokee 4.7L were Denso and having owned the vehicle since new, I know they lasted 10 years. I can’t say for certain if what Denso supplies to Jeep for manufacturing a new vehicle is the same quality as what you’re getting when your purchase Denso aftermarket. I am assuming they should be the same. For significant the price difference between the dealer and Amazon, I am willing to chance it. I compared my old sensor to this one and they looked exactly the same. This was not the case with the 1 Bosch sensor I bought in a pinch at my local Auto Zone. Yes it was the correct part, but the sensor gas collector looked a lot different. Another thing I like about Denso is that they supply you with a generous tube of anti-seize compound to apply to the threads of the sensor, whereas Bosch pre-applies it for you.
As far as “does it work good†? For my 2004 Jeep Grand Cherokee 4.7L, this is the left side upstream sensor. I replaced it in anticipation of it failing because three out of my four sensors failed within two months of each other, so I figured why bother waiting on this fourth one. It was the original 11 year old sensor – how much time could it have left on it? So I swapped it out and even though the service engine light didn’t deem my old one as bad. I do feel like this new one is giving me more responsive acceleration.
Just prior to this a failed right side upstream O2 sensor was causing my exhaust to flutter, the engine was running rich, which was creating a very strong fuel rich exhaust odor and my MPG went from 19 to 10. The check engine light was code read at a shop and it pointed to this sensor. Upon installing the Denso replacement 234-4653(which I was forced to buy locally because I couldn’t wait for one to get shipped given the symptoms), all the symptoms went away immediately, except for the check engine light with took a couple of driving trips (around 30 miles) before it turned itself off.
Some advice:
When applying the anti-seize just hold the opening of tube against the threads and slowly rotate the threads and squeeze a small amount out until the threads are filled. Use the edge of the tube to plow a uniform coating all the way around. If any excess is above the last thread and on the smooth surface below the gas collector itself, be very sure to remove that with a Q-Tip or small piece of paper towel. You don’t want any compound clogging up your new sensor.
Removing an old O2 sensor can be a nightmare, especially since they are normally in there for a very long time and sometimes get quite melded into the threads. It is always recommended to get the exhaust as hot as possible if you are dealing with a stubborn one. On a 2004 Jeep Grand Cherokee, only one of the O2 sensors was in a reasonable place and the others are in very tight spaces, which makes it difficult to maneuver any tool. Chain stores like Auto Zone do offer free tool rental and they do have wrench & socket based tools made specifically for O2 senors that can work around the wires. If that is not an option for you and you are unable to remove with an open-end wrench, you could opt to cut the wires and/or rip off the housing on the old one so you can slip a regular long socket on there, but only do this if you know the sensor is not working, else you’re creating more of a situation. Cutting the wires on verified non-working sensor will not worsen the condition.
I’m assuming you’re reading this review or looking at this product because you are aware that you need the sensor for one reason or another. However if you are unsure if this is what you need or just have a service engine light on, you can most times go to a local auto store to have the service engine code read, which is normally free of charge and you are not obligated to buy anything from them. However, please note that some of handheld code scanners may not be specify which sensor has failed. In my experience, Auto Zone was able to tell me that both of my downstream sensors were fouled as it specifically cited which bank and which senor. However on another occasion when my service engine light came on again, the unit reported that a sensor was fouled, but it only specified the bank, but not which sensor in the bank. I could easily assume it was the upstream sensor on that bank given that I had recently replaced the downstream and that turned out to be true. I got that confirmed beforehand while visiting a jeep specialist shop (not the dealer) because their code reader was a more robust unit tailored to Chrysler/Jeep. It reported the same bank, but it specified the upstream sensor. If I didn’t have this option, I would have just purchased the sensor anyway because chances are there is nothing wrong with downstream sensor I just replaced in the same bank.
Something to consider; if you’ve had your vehicle since new, it’s on the older side, you know it has all the original O2 sensors and you are starting to run into O2 sensor failures, chances are they’re all probably going to fail within a close window to each other. That is what happened to me. First the two downstream failed simultaneously and then one upstream a month later. If I had to do over, I would have just replaced all four of them saved myself: some money by buying them all on Amazon, multiple trips to the auto-store for code reading, gas (I burned twice as much for the few days I was driving before I had a chance to fix it) and I paid $15 extra for the one I bought a local auto parts store and that was the cheapest I could find.

wired up with no issues

Product was completely misrepresented and doesn’t fit a 2003 Jeep Grand Cherokee. Due to other issues I was having with the vehicle I wasn’t able to get this unit installed until yesterday when I found it didn’t fit. Due to Amazon’s return policy I am stuck with the part and had to pay full price for another. Make sure you know what you are ordering or use it quick.

I have a 2001 Dakota with the 4.7L. Check engine light showed up, code was for the 1/1 sensor (front left). The dealer quoted me something in the $150 range for the OEM sensor alone. Guess what – this Denso is a perfect match. The connector is exactly the same as the original. You do need to keep a little red plastic clip from the old sensor. FYI – there is not much space to work with underneath the truck, but with the 4×4 clearance, I didn’t need to jack it up! Anyway, I broke that little red clip while trying to re-attach it, but I was able to use a couple of zip-ties to keep the connector and receptacle mated. Not sure how long that “fix” will last, but I’ll get a nice CEL when it gets brittle and fails! I’m not worried.
Getting to the sensor itself is fairly easy, though. There is a small access panel in the front left wheel well. You’ll need a universal joint, O2 socket, 6″ extension, breaker bar, and a torque wrench (for reinstall).
Save yourself some crazy $, buy this, and do it yourself.

Go to the DENSO site. They list the 4 O2 sensors required by position on the Jeep.
This happens to be the driver’s side front upstream sensor in front of the driver’s side cat. Couldn’t tell this on Amazon’s site because it doesn’t detail the 4 different ones required for the Cherokee. Basically they are all the same sensor but have different length cables and different sockets (keyed differently) so they aren’t interchangeable.
The plug fits very well into the factory harness.
Alternatively, if you can solder, there are versions of this that come with a long “pigtail” of wire that you can splice into your old factory connectors.

It was just what I needed and the best price.

Worked great and no more code installed myself took it the next day after installing the all 4 02 and passed state inspection .

Installed on 2001 Dodge Durango SLT 4.7L 4WD . Removing OLD sensor and accessing wiring harness connection was a bloody knuckle nightmare, but this part worked perfectly!
