Denso o2 Sensor
- Thread starter centxrunner
- Start date
Are you sure the URD was updated? I'm running through this same problem right now.
I have a 2000 2wd non-cali auto. I bought the 4162, like it says in the URD and the cable was too short. I returned it and swapped to a 4154 and the cable is STILL too short for a direct replacement. The female end of the O2 sensor is clipped onto a crossbar and I will have to unclip it and stretch the cable over for it to fit.
Is there a difference between all of these part numbers aside from cable length?

Well I don't run the URD website, so I don't know about updates, but I don't think anyone here has been steered wrong by URD.
Be sure you don't have Cali emissions. I made that mistake and had the exact same problem. Be sure you are actually counting the cats and not just looking at the sticker like I did. I am betting you need the 4155 which is twice as long as the 4154.
Remember, lots of them have cali emissions that were sold in Cali, and have never stepped foot in Cali, so be sure you are actually counting your cats.
I had my Cat stolen a couple years ago and the muffler shop only welded 1 Cat back on. Therefore, along with the sticker that says "not for California", I assume I have a non-California version.
I also have a 4 cylinder, so according to the URD, there is only 1 more possibility of the 4622. How do you check how long the cables are on these without having to buy them?

I got the lengths from the autozone website. Autozone says you should use 4162 which is 10 inches, so that doesn't seem right based on what you're saying.
There's got to be something wrong here. If nothing else, I think you could just buy a 4155 that has 24in of harness length to be safe. I know for certain that the sensor itself is identical in every way other than the harness length, but I think that is the difference between all these part numbers. I don't think they would have different functioning sensors within the same model year.
About to do mine on '97 RWD LTD Non Cali. PartsGeek seems to have cheapest pricing on Denso ----> 97 1997 Toyota 4Runner Oxygen Sensor - Fuel Injection - Bosch, Delphi, Denso, Standard Motor Products, Walker, Walker Products Inc., Downstream, Front, Rear, Upstream - PartsGeek

Use this site (cable length is under the 'Specs' tab:
Denso 234-9002 Thimble Type Air Fuel Ratio Sensor
There is another way to try. Go to Toyodiy.com and give it your VIN. Then get the Toyota part number and plug it into the CrossReference Tab in the Parts search on the Denso web site. That might clear up the confusion.
Note that the 4622 is a non-flange (screw-in type) base.

You can figure this out by looking at the universal sensors listed for the various applications. I think there are only three types:
-flange-type O2 (234-4206 universal)
-screw-type O2 (234-4209 universal)
-flange-type A/F (no universal offered, but I bet they are the same except wire length.)

There is also the 4153 that is 17.7" (flange-type). That sounds about right, if flange-type mounting is confirmed. The 4153 is a listed rear sensor in 1998 for the 4-cyl. Confirmation of flange-type mounting needs to be done, as both the screw-type (4622) and flange-type (4154 and 4162) are listed in 2000. As I said above, all flange-type O2's are the same sensor as they all can be replaced by the 234-4206 universal in any application. Matt, I agree, SOMETHING is wrong, but I have no idea what it is.

I just removed my old O2 sensor. The wire length is 13'' if you measure from the bottom of each connector end. The 4154 measure 10'' this way.
The 4154 is 13'' if you measure to the tip of both connector ends.
Unlike the 4162, the 4154 will actually reach to the connector of the car. The problem is the connector cap on the car has a mount to the chassis. With the connector cap of the car mounted on the chassis, the cable of the 4154 is too short. However, by pulling the connector cap off the chassis, the cable reaches with several inches of slack. Therefore, I zip tied the cable back onto the chassis. It looks stupid, but it fits for now.

OK so I just got a P0171, P1135 and P0125 codes and I'm looking to replace the O2's on my 2000 Auto. I'm a bit confused whether I have Cali emissions or the Federal 49 state. I looked under the hood and saw this sticker, which I believe is the Federal 49 state sticker.
But I looked under my car and I think I have two cats. What is going on?

So I read the post and think I have this correct. I have a CA truck no question about it.
I called the Stealership and they want(Denso pt #-8946735011) 273.87 for it out the door.
I looked on amazon and the Denso number 234-9002 was 125.73
Anyplace I can get a better price on this guys?

Bump, I'm really hoping to order the new sensors tonight or tomorrow. I'll probably stop by the local dealer as well.

I went to the dealership and the guy was just as confused. Gave him my vin and he said it's showing the Air Fuel sensor, but also an O2 for the front. Didn't really help at all.

I think you want the following off URD
1999 & 2000 49 State 2WD & 4WD auto V6; Front = 234-4162 1999 & 2000 49 State 2WD & 4WD auto V6; Rear = 234-4162

If it is Cali Spec it clearly says that on that sticker, at least mine does and its a 1999. I think years 2000 and later all received two cats which may be the source of confusion, maybe someone can verify. If anyone has a model year 2000 and above and only one cat please call bullshit on me. Don't go to the stealership get it off that link I provided you'll save 75% in comparison and its the same part.
[MENTION=92510]Ol'Blue[/MENTION] I don't think you'll find it cheaper than amazon, at least I didn't. goodluck

Thanks, yeah clearly the sticker says Federal, but the two cat thing just got me confused. I'll just go with the 49 State O2 and hope for the best. I was just thinking I can also try to disconnect the plug end and see what plug it is. That will for sure let me know since the AF sensor has a different plug.

Most but not all 2000 had the A/F, two cat Cali. systems. I think 13 states required them by then and Toyota had been switching towards 100% Cali. type. But 2001 was the first year that the Cali. system was installed on ALL 4Runners. So I call BS, sorry.
I usually find the Amazon price to be cheaper as well. 234-9002 is $101.

No. 4Runner o2 sensors and a/f sensors all had 4 wires. They are all heated Oxygen sensors, 2 heater wires, and signal ahnd ground from the sensor. Same for the A/F.
For me that is a Federal 49-state label and a Cali. exhaust. One has to be wrong. I'm researching something, stand by...
