    Will It Fit Your Vehicle?


    Description

    This Denso O2 sensor is the wideband air/fuel sensor that you need for your 02-04 Acura RSX (DC5), 02-05 Civic Si (EP3), and 02-04 Honda CRV. This is also the primary 02 sensor needed for Hondata KPro for the 05-06 Acura RSX.

    Don't be fooled by the much lower prices from other websites that tell you their sensors come in a Denso box but may have been manufactured by someone other than Denso - that simply means you are not purchasing an authentic Denso sensor and are overpaying for a Denso box. K Series Parts only sells real Denso sensors in Denso packaging.

    This sensor is a direct replacement for the Honda/Acura parts: 36532-PRB-A01.

    This Denso oxygen sensor is direct plug and play so no cutting or wiring is required for installation.

    Denso Description

    DENSO's light duty oxygen sensor started to appear on vehicles with the development of fuel injection systems. The basic job of the sensor is to monitor the air fuel mixture under idle, moderate acceleration and cruise conditions. Under heavy acceleration the oxygen sensor goes into "open loop," which basically means that the engine management computer system ignores the oxygen sensor. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio.

    As the automotive industry continues to improve on their standards DENSO is keeping the pace with advancements in our engineering to meet the demands from the industry. Also, as car owners are holding on to their vehicles for longer periods, DENSO continues to make auto parts available for those critical replacement parts for all applications.

    Oxygen Sensors

    Oxygen sensors, also known as Lambda sensors or O2 sensors among some vehicle manufacturers, are among the most sensitive and critical components on your car's engine. Earlier fuel injection systems employed one oxygen sensor in the exhaust system to maintain closed-loop air/fuel mixture control. However, today's engines may use as many as four sensors, which monitor not only exhaust gas oxygen content but catalytic converter efficiency as well. In order to perform these functions properly, the sensors must adhere to OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt driveability and illuminate the malfunction indicator, resulting in costly and time-consuming repairs. DENSO First Time Fit® oxygen sensors are designed to meet those tolerances and more. The DENSO oxygen sensor catalog offers one of the most complete product lines in the industry, from Acura to Volvo.

    what u pay for , is what u get !

    Installed on my 2004 civic si ep3 after diagnosting it had a bad 02 sensor, CEL came off right after install. Car feels a lot more smoother at idle , gas mileage got a bit better, definitely worth the $$, Kseriesparts has the best deals and I will definitely continue to buy from them

    Took care of my CEL

    CEL light would turn on. And my rpm would go too low when car @ stop. Just a littl push of gas and it would stall. It would go away when i open the fuel cap. But withing few days it would come back on. Eventually after a few months. It just stayed on. After getting a free read @ local autoparts & from reading @ few forums. Idecided to replace this sensor. Its pretty easy just raise the car from passenger side high enough.Took off the side skirt to make it a little easier. Having the O2 sensor rem. socket also helps but not necessary. Car runs great now. Super fast shipping!

    Replaced sensor to remedy codes

    After receiving the dreaded 'check engine light' I checked the codes with a code reader. They were two related to the secondary O2 sensor - slow or no response; heater failure. Replaced the sensor (make sure you get the tool from Autozone to get it out of the cat easily, it's in a recessed area, but you can see where the wires head in near the engine side of the cat) and the codes are gone. Be careful when you hook the wiring back up, mine came loose and had to be reconnected a second time. Whoops! The sensor seems fine (I mean, it is the original equipment) and the original lasted from 2003 to late 2009, 6 years ain't bad I guess.

    CEL Solved

    A trip to Advance Auto to get the codes, diagnosed cel w/ dealer manual found online. Took a few evenings to diagnose with a multi since I'm a novice. But, took 20 min to remove old sensor and drop in this one in a parking lot with a "curb hop". Saved a few hundred by avoiding dealer/mechanic on this one.

    Can't beat the price, mine went out when I installed the OBX (v2) Raceheader on my EP3 and the o2 CEL code went out immediately. The extra length (for it being made for the RSX) gave it some slack as well :P Thanks a ton CRSX!!!

    Couldn't be more pleased

    The 02 sensor was a great price, came in quick, and was a direct replacement so really, I couldn't ask for anything more except: CRSX may want to offer an 02 removal socket so those who don't have one could get them at the same time. US 02 sensor sockets are easy to come by, but it's harder to find the correct metric one in the typical Autozone type stores.

    Buy it here...

    I looked around for a replacement primary sensor and either none were available or they were too much $. Trust me, buy it here, the price is the best you will find, shipping was ultra fast (3 days to get to Massachusetts) and clubrsx is easy to work with. I shopped around for a while trying to find a better deal and it was just a waste of time. Other than that, the sensor works perfect. I've put a little over 2k on my car since installing the sensor and the CEL hasn't even blinked once at me. The engine runs smooth again and my gas mileage is back where it should be.

    Great Product

    My Primary 02 sensor went bad not too long ago. I ordered this one through club rsx and received and installed in less then a few days. Easy install on my race header. Simple unplug and replug. CEL is gone and my gas mileage has gone up a good bit. I recommend Denso.

    Worked Great

    I got a CEL and determined that I needed to replace the Primary O2 sensor. Like others here I first tried to order from a couple of online stores that claimed to have it in stock but actually didn't. In fact, one tried to sell me a more expensive off-brand sensor after taking my original order. I canceled those orders and found it here at Clubrsx--for a better price to boot. Installation was easy with the right tools and my CEL is gone.

    Great service and hassle free ordering

    I originally tried to buy the same o2 sensor from some other site but they let me order without telling me that they were out of that part until the next month! So I canceled my order with them and got this part from ClubRsx and the whole process was seamless. The sensor works as it should: got rid of my CEL and it seems that I have better gas mileage now than even before the CEL came on. If you have a part you need and you find it here on ClubRsx, don't waste time and just get it!

    excellent OEM

    The O2 sensor took away my CEL, and now im getting better gas mileage again, it doesn't smell like sulfur, and on startup, i don't smell gasoline anymore. So it is worth it replacing it, and no procrastinating.

    type s 03 pre cat o2 sensor

    Well it was worth the 180.00 to purchase a non used o2 sensor. Easy, Direct, a little tug but that that's about it. And the offset socket and wrench to wich i purchased at a local autoparts store made it reallly simple. I am having better gas mileage, shifting and throttle response is great. And yes it was cheaper than everywhere else especially being by DENSO.

    Perfect fit!!

    This was a perfect fit for my 02 RSX-S. Took only about 5 minutes to change (make sure you have an offset-style O2 sensor socket). Great replacement item for an engine with 100k+ miles on it. Engine is smoother, slightly more torque and (perhaps most importantly these days) gas mileage is back up to 30-32 mpg.
