2006 Audi A4 Air / Fuel Ratio Sensor - Upstream Denso

I was more than impressed with the speed at which this item was delivered as well as its performance once I had it installed.My 2003 Honda Accord Ex's check engine light that has been on for months went off once i had it installed and fuel economy has greatly improved overall.To potential buyers: You couldn't go wrong with buying OEM parts from AutoPartsWAY prime at a most reduced price.The dealership were going to charge me 350 for parts and labor and the lowest price i got elsewhere was 320.Took this item which cost me less than half of what I would have paid at Advanced Auto Parts,AutoZone and Honda to a local mechanic workshop and labor cost just 60 Dollars!!! This saved me more than 200 Dollars as !!!

Great sensor... terrible instructions. I know that might sound funny because what all could you need? Put the round peg into the round hole.... Well, they include a tube of...what? Anti-sieze? it isn't labeled... and from what I could tell they already pre-applied anti-sieze. What about torque? Nothing. Their online instructions are no help either. I had to use the internet and my shop manual. I still rate it 5 because it does everything it is suppose to, fixed my code 0133.

OEM fit. Worked perfect for my STI

great price compared to local parts stores. Fixed the o2 sensor issues on my 02 outback 2.5

This upstream oxygen sensor for my 2001 Forester fit perfect and got rid of my trouble code.

CEL came on, and was alerting for this sensor. Replaced it with this and the alert has cleared. Denso is the OEM brand so don't settle for something else. A forewarning, the connector is buried on top of the transmission so be prepared for some extra effort getting the old one out. Upon resetting your ECU, two of the tests require very specific drive patterns to trigger. You can download the drive patterns from Toyota. I also bought a bluetooth ODB-II interface just for this. If you are the DIY type such as myself, I highly recommend you getting that as well. It turns your phone into a ODB-II computer.After installing this and performing the drive patterns, my truck passed smog in California with no problems. Doing this myself saved me lots of money @ a mechanic.

Installed this on my 2003 Honda Accord V6 (Rear, upstream).This is a direct-fit - the OEM one I pulled out looks IDENTICAL.Works great so far.Both codes p2251 & p0134 cleared after ECU reset (pull the ECU fuse from the fuse box under the hood for a few seconds, then re-insert).

I needed a new O2 sensor for bank 1 (pre turbo) on my 04 WRX, The brick & mortar shops wanted over $200 for this part, WELL above what I paid for the part + overnight shipping on AutoPartsWAY! When I removed the old part from my car, lo and behold, it was the EXACT same part number as I had purchased on AutoPartsWAY, so while it's not advertised as OEM, it is the same exact part as was put on my car in the factory. Installation took about 30 minutes.

This fits a 99-00 Toyota 4runner 3.4L 4wd manual transmission california emissions.Denso is a quailty product. This is no exception. check engine light is off and gas mileage has improved.Installation easy, PB blaster is your friend for the exhaust bolts. To get to the plug I suggest going into the cab and removing the plastic and faux-leather shroud around the shifters. The plug will be sitting right there and is easy enough to remove.

My '01 4Runner VSC and check engine lights came on at about 130K miles, pulled the code and sure enough the infamous P1135 Air/Fuel sensor code. Some internet research indicated this was a simple DIY job requiring a 12mm and 10mm wrench and about 30 minutes of my time. Since I have the dual catalytic converter emissions model it required replacing the forward sensor, which is an Air/Fuel sensor, not the less expensive O2 sensor. Apparently single catalytic converter models have an O2 sensor in this location. You can crawl under and look at the exhaust, look for small muffler looking objects inline in the exhaust pipe, and if you have two then you need this Air/Fuel sensor to address P1135. The sensor is located on top of the exhaust pipe where it angles up towards the engine, towards the front of the car (passenger side). It was pretty easy to find by simply crawling under the 4Runner behind the front passenger wheel.This Denso brand is apparently original equipment...

Fixed my issue, exact replacement, ECO light comes back on againHard to get to and remove connector from bracket but worth the time and effortI used (AutoPartsWAY bought} Powerbuilt 648691 Oxygen Sensor Offset Puller to remove the sensor

I own a 97’ V6 Toyota Avalon with California emissions. Denso and AutoPartsWAY stated that this was the spec’d part for California vehicles. Denso also listed part #234-4622, however #234-4622 is excluded for California vehicles.Much to the frustrations of other reviewers here I found that this part #234-9007 did not fit my vehicle. The connector plug is different and incompatible with my vehicle. The connector looked the same until closer examination where you could see one side of the plug’s plastic wall is clearly different. Other had stated that there is a sticker next to the hood latch, but that is not the case on my vehicle. However if you don’t find a sticker next to the hood latch it should be located on the firewall on the driver’s side next to the brake vacuum booster. The sticker is white with red writing on it. However be aware that the sticker does not come right out and say Calif emissions, but in the sum of the long paragraph you...

I found this item to be indeed a direct replacement. My Toyota is a California emission vehicle, as indicated on the inside of the hood. Great price on sensor.

Get rid all my error codes and recently pass CA smog check without any problem with my CA Toyota Camry 1999.

so far so good my Toyota is running the best it has in years. i went to denso sit first to make sure that i got the new and right part first. it is also official part maker of Toyota

The car: 2003 Subaru BajaThis replaces the upstream O2 sensor, also known as the Air Fuel Ratio Sensor. The electrical plug fits perfectly, without any need of adjusting. It even comes with a small tube of copper anti-seize for the sensor's threads, in case you don't already have some.Note: The sensor location is not easy to reach with a socket wrench and O2 socket. It was easier to just use a 7/8 inch open end wrench. -Which was even suggested in my Haynes manual.

OK, technically it's an air-fuel ratio sensor.Physically swapping out the sensor was a piece of cake on my 2002 V6 Manual Tacoma, but reaching the electrical connector above the tranny was a bit more difficult. Still, all in all not a difficult task and I'm by no means a gearhead. Worked perfectly, no more code. Ordering this part saved me at least $100 just on what the mechanic wanted to charge me for the part, let alone labor.AutoPartsWAY's "Garage" also saved me from ordering the wrong part (almost got the 234-9001). Thanks AutoPartsWAY. Make sure you really check, just having a 2002 Tacoma isn't enough, there's a ton of different sensors for different engines, trannys, and even trim.

THESE ARE OEM SENSORS. Too many non-mechanics on here second guess the product. These are OEM, and will fit your application.This is for BANK 2 SENSOR 1, and BANK 1 SENSOR 1 applications (front sensors).BANK 1, SENSOR 2 is the sensor that is immediately before the Cat, so that is a different sensor which is cheaper. It is the sensor at the bottom of the car.This will likely solve P1150, P1130, P1133, P1153, P1135, P1155, and possibly Interrelated code P0125 insufficient coolant temp error.

For California emission model vehicles (ULEV). It cleared my check engine light on a 1999 Honda Accord! It took me awhile to find the right part...had initially had the wrong one in my car.

This is the OEM front oxygen sensor for an '02 Subaru WRX (among other models) at a really good price. Plugs right into wire harness.

After having this for a month on my 05 wrx, the sensor is doing the job. No CEL anymore. I've read that this is a direct replacement on the car without the markup. If subaru puts its name on it, its $165 approximately. I strongly recommend this as a replacement. My stock sensor failed me after 106k miles. Hopefully this one will last just as long.

2002 RX 300 Bank 1 Sensor 1 Replaced. Inspections passed!Worked like a charm.Jack up vehicle on passenger side. Place jackstands x2Slide under from front. ( make sure vehicle is cold )Locate SensorUnplug wiring harness test with OHM meter. (mine read 0.0) (new one read 1.8)Use an O2 sensor socket with ratchet wrench. ( I gently used a breaker bar, 132K miles on vehicle)********* don't forget the ANTI SEIZE goop (comes in package, I forgot to use it, oh well) ****************

Exact same OEM Denso part as sold at Toyota dealer for $30-$50 higher price. Sensor comes with small packet of high-temp anti-seize paste and instructions. Original Denso sensor lasted 203,000 miles in my Japan-made California-spec 1998 Camry V6, so the only logical choice was to install another Denso sensor. Beware, replacing the sensor on the rear cylinder bank (Bank-1, Sensor-1) of a Camry V6 is NOT a trivial task because of very limited access to sensor and connector. Very satisfied with product, pricing and quick delivery. People complaining about sensor "not fitting" either don't know the difference between California-spec and Federal-spec vehicles, or don't know the actual model-year of their car. Verify vehicle build date on VIN plate located on driver's door frame before ordering sensor.

I got a 99 4 cylinder camry which got the CheckEngine light along with a trio of code: P0171, p1130 and p1135. It also gave strong smell of gasoline and got miserable MPG (around 12 MPG suburban).After a careful study of online materials, I decided that it is a problem of the O2 sensor. It is confirmed by my mechanic, he insisted that I should get the part from dealer, costing $265 plus tax.I refused and purchased from AutoPartsWAY, saving more that 60% on parts. I brought it the a local mechanic. He changed it for me for half a hour of labor. But really it took him literally five minutes to remove the old one and had this one installed. He didn't even need to raise the car above the ground, just used a long handled tool to do the work above.All the problems mentioned are gone for now, hopefully they should not be back for a while.A piece of advice: the problems should be handled asap, before the converter is poisoned/damaged by the...

Exactly what we needed for my 99 Lexus RX300. Installed the new AFR sensor in about twenty minutes. My gas mileage improved from 12 mpg to 19.5 mpg (mostly city driving so I hope to get even better when we take a long hwy trip). The reveiws on AutoPartsWAY helped me make the right choice for my vehicle. thanks!

I ordered this A/F sensor for my 2002 Sienna (bank 2, sensor 1; the easy one on the front exhaust manifold). It came fast by USPS in sealed packaging, complete with the anti-seize compound. It looks exactly the same as the original - the sensor, the wire length/color, the connector - it's the same thing. Removing the old one was hard: several rounds of PB Blaster + time, hard to unplug the connector - push in the plastic securing tab on the connector facing away from the engine! Installing this new one was simple: some anti-seize compound on the thread (only!), screw in by hand, then tighten with a wrench with feel, snap in the connector, put back the clamp holding the wire in place = I just saved at least $200 compared to the dealership charge.

Lisle 12100 Oxygen Sensor Socket

My wife's 2001 Toyota Sienna had the Check Engine Light (CEL) on and was a P1135 error code (faulty signal O2 Sensor) on the Bank 1 Sensor 1 (which is on the back of the engine by the firewall). I bought 1 of these to replace the one the error code indicated... it was a perfect match, but after clearing the error code, a P1155 error showed (the one in the front of the engine... easier to get to) which at 117,000 miles should have been expected. I ordered a second sensor and now we're all good. (OEM has 2 different sensors... the back one had a slightly shorter wire lead... aftermarket they use the one with the longer leads (this product) to replace both front O2 Sensors.)If you have a high mileage car, you may want to replace both... it is a wear item.Helpful resources1) The Toyota Tech document to help you determine where the sensor that needs replacing really is:[...]2) Good video here for how to replace the Bank 1 Sensor 1 (tucked...

Although not listed as compatible this sensor (234-9015) is direct replacement for factory sensor 2004 Subaru Forester non-turbo. Original Subaru part is exactly the same sensor, all construction is exactly the same as the one I pulled from the car except wiring insulation color.All retailers list different sensor for this Subaru model, but electrical connector does not fit.Cleared P0032 code nicely.Update October 2013 - 3 years and 40 k miles later it is still going strong.

I used this part to replace the California Emissions Air Fuel Ratio Sensor on my 99 Camry V6. Dealer wanted $277 for the factory OEM replacement part, but since the original part I removed was a Denso, I thought this part is probably equivelent to the OEM replacement part. According to my code reader and the manual the bad sensor was bank 1, sensor 1, also referred to as rear sensor before the catalytic converter. The after market parts are referenced as front right or front left. It required some research, but I determined that bank 1, sensor 1 is the same as front right in the after market parts. Long story short, I installed this sensor in my Camry over two weeks ago, cleared the diagnositic codes, and check engine light has not come back on. This part saved me over $150 from the OEM raplacement part.

My 4runner had 70,000 miles when the oxy sensor coded. Average is around 75,000 miles. The sensor ahead of the cats-california models had 2 catalytic converters and is also called the "air/fuel sensor" on those- is usually first to go.Replacement is basic. Now the annoying "check engine" light is off, and the engine is running per spec. Denso is considered the best replacement brand by most toyota fans.

I made the mistake of actually trusting the nimrods at Auto Zone when they told me what the right part was for my 2000 Honda Accord. Turns out that the ULEV (aka CA emissions) version of the car takes a more complicated/expensive O2 sensor; it also has a slightly different name depending on who you talk to. Those guys are dipsticks: never trust a part recommendation from there or Advance Auto Parts unless you actually know the guy has some brains. Got the right part here no problem. The Denso OEM replacement has been working well...absolutely no complaints. Make sure you get the real part number off the one you are removing and then go to the manufacturer's web site for replacement numbers. Always a learning experience when it comes to auto parts.

Like Javier, I had "Check Engine" and "VSC Trac" lights on a 2001 Toyota 4Runner. Had an auto parts store pull the code (P1135) from the truck's computer, and decided to shop around when they wanted $200 for the part. I saved about $70 by buying the part here and probably $60-80 more by doing the repair myself. It's not a bad job, especially if you search online for a how-to. The hardest part was actually unplugging the connector on the old sensor. Looking at the new sensor helped me to figure out how to do it; basically I used a small screwdriver to lift up a tab that locks the connector into place. Also, once the new sensor is installed you may need to disconnect the battery in order to reset the computer and turn off the check engine light. Once I did that, the problem was fixed!
