Denso 234-4137 Oxygen Sensor

I got the original since so far I have went through a Walker unit that lasted just 1 year and 5 months and I paid 25 bucks more for it at auto zone. Naturally there is no warranty coverage. I recommend to get insurance on it. Strange that it did not last longer. But, Walker will not cover it now so I decided to get this Denso,

Fits perfectly on 1997 Camry 4 cylinder.

I bought denso part no. 234-4137 (o2 sensor) in jan 2018. I have a 1999 toyota camry 4 cyl (kentucky built) with california emission spec. Had 0136 code check engine light (downstream o2 sensor). I prefer denso actual replacement part or oem parts, but they are now costing $200-300. so I went with this one. One review said they thought its actually a universal sensor, so I was worried that it might not take care of the check engine light, even if it was getting close enough performance that the car would run decent. So I was happy to find it works fine. Car is running better with better pep (since it can now adjust everything as its supposed to) and check engine light has been off 2 weeks. I cleared the code after installing, and it never came back on.

This is the OEM 02 sensor for the 97-01 Camry 2.2l 5S-FE engine with California emissions (not sure if it is OEM on Camrys with Federal emissions). It should work like your original as long as you have a healthy engine. The only thing that I can see that's different is the factory sensor had a wire shroud over the wires and this one has exposed wires, so consider using wire loom to protect it. Also, if you happen to do the dumb thing I did, learn from my mistake.... While I had the radio on (key turned to "accessories"), I cut the wires on the original sensor to use as a pull-thru for getting the new wires attached under the driver's seat. When I went to start the car, it only cranked. When I finally realized what I had done, The first thing I thought was I may have just blown the car's ECU. Turns out that shorting anything in the car's emissions or fuel delivery systems simply blows the 15A Fuel Pump fuse so you cannot start the engine until whatever blew the fuse is repaired. This is further proof of a great design. I should have disconnected the battery ground before working on the car. Duh!

Great part. I did my research, and for my Lexus (Toyota), everyone said to use this Denso part. Good pricing. Do a youtube or other search on how to change this part. Seems easy, but the connector goes up into the car. my connector was under the driver's seat. Never would have looked there! With some effort, I was able to use the connector, and not cut wires. take the time and do it right. side note, I saw info that changing this sensor MIGHT get rid of the Bad Catalytic converter code my car was throwing.. and it did, for two days. Luckily I was able to pass the emissions test, then the C.E.L. came back on. so fast forward to December (from August), I finally changed the Cat (direct fit Walker 16130), and my C.E.L. finally went off. this sensor is still working!

These are exactly the same brand as my local parts store carries but they are half the price. Part installed and functioned as it should and took care of my check engine light. This was installed in a 1998 toyota camry with a 2.2l engine

Contacted the seller. I was assured this would work on my California Toyota, since California has different specs than the rest of the country (idiots.) Did not work, was not the right part. It was the version that works for every state EXCEPT California. Waited to long to have it installed and am now out $60. These people don't know what they are talking about.

Perfect fit for my 98 Camry. I would have given this five stars but I didn't like its thin wire sleeve. The sleeve is thinner than the original sensors so doesn't offer as much protection for the wires. Other than that it's good quality and reasonably priced.

First of all, a Sensor2 error code (Downstream of CAT) isn't as big a deal as a Sensor1 error codes (Upstream), but we got tired of reconnecting the battery terminal every month to remove the amber check engine light. Secondly, a Sensor2 failure seldom happens, but we're talking about a much older car here. Anyways, got under the car to unfastened it and learned to route the wiring from beneath the drivers seat (Thank you YouTube) without removing the seat. Teens are happy, wife happy, happy life! Lol.

1 month in so far so good. This is supposed to be the OEM manufacturer for Toyota and amazon has it for roughly 1/4 the price vs Toyota and not counting tax, so it's even less. Reset cpu after install to get rid of check engine light, drove 1 week and passed emissions test no problem. Will update if any news but do far so good. Very satisfied with prompt amazon 2 day delivery also. Definitely recommend.

Excellent OE part. Cleared 'CE' Light (DTC-Code P0136) after 30 km of driving.

Fit my 98 lexus ls400 perfectly. No problems with installation, or resetting codes.

Old manufacturing date but good price and works well.
