I had to replace this sensor on the wife’s car. I can’t remember the bank or sensor number I needed to replace, but just like with my RX300, I went to Denso’s website to make sure I had the proper item and then came here to Amazon. I saved about $20 over buying it directly from Denso, and about $35 over the local parts store.
Replacing this sensor on the wife’s car necessitated removing the carpet on the passenger side and feeding the wire through the floorboard/firewall area. DO be sure to use the anti-seize compound to help with removal the next time. Just put the compound on the threads of the sensor, don’t bother putting it on the exhaust pipe.
This sensor was a bit more difficult to remove than on my RX300, but I believe that was due to me not using anything to loosen rusted/stuck parts. On my RX300, the following process worked quite well for me, and I recommend it anytime you need to replace one of these sensors: The day before trying to remove the sensor, as with the RX300, I put some Kroil Kano Kroil Penetrating Oil, 8 oz. liquid (KROIL) on/around the sensor threads and tapped the sensor to help it start seeping in. I would let the Kroil sit for about a half-hour, then put some more on, tap it, head inside…after doing that for a total of 3 times, I let it sit overnight.
I bought this version because it has the connector already done. If you’re handy with soldering, you could easily cut the connector off the old (bad) sensor and solder it to the connector-less version of this sensor and save yourself an additional handful of dollars. Had I realized this earlier, I would have likely taken that route.

Decent price for original equipment. Would be nice if they included the specialty 22mm split socket for us DIYers to get around the wire.

Purchased this O2 sensor for my 2004 Toyota Camry LE 4 cylinder that had a check engine light illuminated and a PO136 bank 1 sensor 2 error code. This is the O2 sensor that is downstream from the catalytic converter (not the sensor that is on the exhaust manifold pipe accessible via the engine compartment). Removing the failed sensor required getting my Camry on ramps so I could comfortably crawl under the car to use a 24″ breaker bar wrench extender to spin out the old sensor. I could not budge the old sensor with a wrench and penetrating oil alone. This O2 sensor has electrical wires and rubber grommet that allow the connector to travel through the floor of the car to make the electric connection inside the car (often under one of the front seats.) My model Camry has the electrical connection on the underside of the car. I coiled the extra wire and secured it to the underside of my car with zip ties. This sensor also comes with a small container of goop which you can apply to the threads of the sensor to make it easier to remove in the future. Do not get any of the goop on the sensor probe. After driving about 15 miles, the check engine light disappeared.

Engine light was on. Called for bank 2 sensor 2. This did the trick. Was able to get car pass smog and registered. Thanks!

Fit my 2004 Camry and was able to install. Had the problem with many other O2 sensors with the wire being too short, but this one had plenty to spare so I just tie wrapped it.

It was too late to return this before I discovered that the rubber boot that seals the wire through the floor under the car was on backwards. I spoke with Denso about it and they refused to honor the warranty because it was purchased form an unauthorized dealer.
The only solution is to cut the connector wire, reverse the boot, and solder and waterproof the repair.

Vehicle used on: 2003 Camry LE 4 cylinder.
Problem: Check engine light threw a P0420 — Catalyst system efficiency related code. I did some research and narrowed it down to the downstream o2 sensor. After FURTHER digging, I settled on utilizing the “Spark Plug Non-Fouler” trick (google it). I’m not going to go into details for that.
Basically, this part will save you more than a hundred dollars if you order here on Amazon compared to the stealership. The wires on this o2 sensor are EXCESSIVELY LONG, so I needed electrical tape to bind them together so they don’t flop around and hit the cat and exhaust. Also, the fitment for a 2003 Camry is WRONG. The grooves are all incorrect so it didn’t click/fit into the receiver. I had to grind down the grooves on the cement so that it would slide in, instead of bothering with returning the unit and getting correct one. Still worked, just had to modify it a bit so beware.
LASTLY, getting off my old o2 sensor was a pain in the butt. I HIGHLY, HIGHLY recommend going very liberally with the copper anti-seize that comes with the o2 sensor. This way it will save the next person grief when removing it should something happen.

Denso is a great product for Toyota vehicles and is built to last. Good value and easy to install.

My Lexus GS300 was displaying check engine and VSC light. I took it to a shop to pull the error code, they said my O2 sensor on Bay 2 was bad. I asked them how much will it cost me to fix the issue, their estimate parts $195.00 and $95.00 labor. It seemed pretty high so I did not get it fixed. I did some Google search and came upon this product. This fits and works perfect. Only minor point is that the rubber stopper does not fit as snugly as the original but close enough for the price. I put it in 3 weeks and so far working very well.
