The cord is like 4” shorter than the one I’m trying to replace, and would reach so couldn’t install. I contacted Denso to advise.

I CAN ONLY SPEAK TO THE OVERALL IMPRESSION OF THE PRODUCT AS RECEIVED; I AM NOT A MECHANIC.
PRO: APPEARED TO BE WELL MADE QUALITY PRODUCT / FIT ITS LOCATION EXACTLY; CONNECTOR AND LEAD LENGTH WERE RIGHT ON / SUPPLIED WITH ANTI-SEIZE COMPOUND / BOXED IN MANUFACTURERS BOX WITH PRODUCT IDENTIFIERS CLEARLY MARKED
CON: I WAS SOMEWHAT CONFUSED INITIALLY BECAUSE I ONLY RECEIVED ONE OF THE TWO POSITIONS I ORDERED AND THE BOX HAD TWO IDENTIFIERS ON IT; ONE, AS “OXYGEN SENSOR” AND ANOTHER ( WHICH I REALIZED A BIT LATER WAS THERE) WAS “FUEL AIR SENSOR”. I INITIALLY THOUGHT THAT SUPPLIER HAD SENT THE WRONG PRODUCT AS IT DID NOT FIT IN THE LOCATION I HAD TRIED IT IN ( THE WIRE HARNESS CONNECTOR WOULDNT FIT) . WHEN THE SECOND ONE CAME AND I COMPARED THEM I FOUND THAT BOTH WERE CORRECT FOR THEIR “SPECIFIC” LOCATIONS; THE SENSORS AND THE CONNECTORS ARE LOCATION SPECIFIC SO THAT THEY CAN ONLY BE CONNECTED AT ONE LOCATION. ONCE I HAD THAT SORTED OUT EVERYTHING WENT WHERE IT WAS SUPPOSED TO GO AND ALL WENT SMOOTHLY. ENGINE RUNNING SMOOTHLY NOW. HINT: BEFORE DOING ANYTHING COMPARE THE WIRING CONNECTOR TO THE COMPLEMENTARY ONE AT THE LOCATION YOU ARE TRYING TO INSTALL THE NEW SENSOR IN; THE WIRING CONNECTOR SHOULD SLIDE IN EASILY.

For price its great so long as it works but the in stock count climbs up and down.
The box was crushed and it had those classic lines that form when the box has really been crushed for a while so the internals of the box show the insides inner center lining. Did I mention this is the original packaging? Yes the original box.
Add to that the mailing box that came which read crush pressure to 29 lbs label and it looked like a gorilla squashed it! Naturally the box was still sealed amazingly. You would think for a +$100 item just bigger than a bunch of pencils would be packed and sent with more concern.
Add to that, it almost arrived late as after complaining it was 2 day delivery and it was not processed for a day, how could it make it on time. Noticed the new updated ship time after the complaint.
So all that builds into my confidence naturally. Since this sensor was a solid item and not something fragile, I kept it. Lets hope there won’t be troubles from the way it got to me. Disappointing experience again.

When the cheaper, non-OEM oxygen sensors failed to resolve my car’s ECU ‘check engine’ code, I purchased the identical parts that came in the vehicle from the factory (Denso, which is the same part sold by Toyota dealers with a Toyota part number at a huge markup). This is the second time this has happened to a family member’s car and Denso sensors have resolved the issue on both occasions. Unlike some cheaper generic sensors, these not only work to original specs (duh), but will last much longer than the generic (or Bosch) substitutes. So, these should last well over 100K miles like the original ones they replaced.
If replacing these yourself, it’s a relatively easy job. Just unplug the harness, unscrew the old sensor, screw in the new sensor, and plug the new harness back in.
If care and the proper tools aren’t used, however, one can easily strip the threads, since the heat seems to ‘weld’ these sensors on over time. I recommend PB Blaster (to avoid stripping the threads) and going slow on seized sensors. Use a six-sided O2 socket (or 6-sided wrench in the tight spaces of some newer cars), and make sure the force you exert is parallel to the threads. Avoid straining with a small socket wrench, as it tends to casue the force to ‘tilt’ the sensor, which can leave the softer metal of the sensor threads stuck in the exhaust’s sensor port. Avoid this, even if it means using a breaker bar or pipe extension. Having to pipe-tap the threads or pay a mechanic to do it will totally ruin your day.
Also beware shady mechanics, who have been known to remove good sensors and replace them with faulty ones, in order to rob you of $300 or more to fix it.
Use a good OBDII scanner that has the ability to record all the ECU/sensor readings prior to leaving your car with a Mechanic. Then when the scumbag tries to scam you, report it to the authorities.

Installed this in my wife’s 2002 Toyota RAV4 a couple of months back, best price I could find. About half of what the local auto parts stores could offer. Car runs fine, the check engine light is off, all is good. Highly recommended!! You might want to get the special slotted socket to install it. I got one thru a loaner tool program at a local national-chain parts store, might want to check into that first. Pay a deposit, use a tool and return it, deposit refunded. Works great for tools you probably would hardly use otherwise for special jobs like Oxygen Sensors.

The fact that I could buy this Oxygen sensor from Amazon was awesome. It saved me so much money and it’s working great.I am a girl and unlike other reviewer who could replace the sensor by themselves, I couldn’t. But I asked a mobile mechanic to do that for me and it was much cheaper than going to a toyota dealership or somewhere similar. I totally recommend this product and specially for those unlucky people out there like me, who needs to replace all four oxygen sensors on their car. The auto mechanic that replaced the first oxygen sensor on my car cost me 360$. I bought all the other three oxygens sensors from here and I am glad I could find them here.

My 2002 Toyota Rav 4 finally threw out the P1135 and the P1155 codes after 214K miles. That is both Bank 1 and Bank 2 sensors. I’d say this was a good run on the original part.
When I went to the local part store, they wanted $180 for a no-name brand that I questioned if it would last half as long as the original part. Well, thank God for this part on Amazon. Not only is the OEM part, but at $80 cheaper. I saved $160 right off the bat.
When it came time to install them, I was a little hesitant due to the fact that the original ones had been mounted on the exhaust for well over ten years. From everywhere that I read on the net, they recommended warming up the engine before attempting removal. To my surprise, the instructions included with the sensor states to remove them with the engine at room temperature. I decided to try the room temperature method first and see how that went. Low and behold, they came off with no fuss. What a relief! Ten minutes later, I was done.
Now, I never reset the trouble codes from the car’s computer so as to see if the new sensors would solve the issue. After driving the car for about 30 minutes and then parking the car for a couple of hours, the check engine light reset itself. Done, done, and done.
Don’t buy no name sensors that can be a gamble whether they will last or not. Buy this OEM part at Amazon and get it done right the first time.

Fits perfect. The check engine light was gone in less than 2 minutes after i started the engine. I still have to erase the code because the obd is still detecting it. It’s been a month now and so far the check engine didn’t come back. The car passed the state inspection. This oxygen sensor is for upstream right, which is the passenger side.
