I own a 86 toyota 4x4 auto 22re truck and I am having a hard time finding the right o2 sensor outside of buying it from toyota which is way to much money. Any ideas?

 

autozone or advanced auto carry both oem and aftermarket. Use original brand, it sticks farther into exhaust stream. I had a lot of problems with the shorter aftermarket unit.

 

I've had fairly good luck with Bosch universal O2 sensors- had two (yes, two- damn dual sensors) on my 91 truck for over 15,000 miles and it hasn't thrown a code over 2 smog tests... my 91 passed California HC and CO emissions (but not NOx) with a technically "inoperable" converter (read as "blown out" and no catalyst inside). I have to owe some debt to the O2 sensors... that's all I have to say about that.

Just a word of warning- the instructions state to 'match' the wires so the wiring to the new sensor is the same length as the old one... to which I say hogwash... make the wires as short as possible while allowing for movement. Longer wires = more resistance. More resistance = delayed response.

 

find the part number and type it into amazon.com they had a Bosch for my 89 and i payed something like 40 dollars for it with free shipping.

 

It is a nipondenso part number, I googled it but didn't try amazon. I guess it is going to be just a Denso now since they changed their name. I work for a automotive electrical shop (starters, alt, and gen only) I have found that there are two different types and the varry bassed on what VIN you have. I think i'll be sneaky and call toyota, get what part no it is going by now and buy it else where......

These are the nos on the sensor

ND 065500-223 and there is a toyota number too: TOYOTA 89463-12030

I can't find these numbers anywhere online....

here you go...

 

http://www.sparkplugs.com/ is where I get mine, they carry the genuine Denso sensors. Generally the Bosch sensors do not work as well on the Toyota engine, they tend to have a shorter sensor tip and don't stick down far enough into the exhaust stream like the Denso units do.

well then here you go... free shipping too!! just gotta find something else to buy

 

Just have to throw this in........

I don't see how the length of the sensor probe has any significance on the 22re. The exhaust is propelled strong enough to reach it. We're only talking about a relatively little difference in length, anyway. The main problem I found with the Bosch unit is the how it fits. The diameter of the manifold port is smaller than the little lip under the flange where it seats on the threaded portion. What I really noticed was that the flange had bent over from torquing the nuts down whereas with a Denso or NGK unit the flange torqued down completely flat. I dunno........maybe for the fact that there's a gasket and the gasket seals regardless it doesn't matter, but that's the only difference I've ever noticed between the brands. The Bosch I ran worked enough to detect an oxygen imbalance due to a bad AFM. Still, I went with an NGK after replacing the AFM. Sounds cooler to say that's what I have in my Japanese vehicle, anyway. Hehe....

 

I've not run a Bosch sensor myself but have heard many folks reporting issues with them (note on my VW I try and run only Bosch electrical parts because they work the best there). But I have had issues with an NTK O2 sensor which also has a short sensing element. It was a relatively new sensor (maybe 2 years old) and I would get periodic O2 sensor errors while with a much older Denso sensor, I would get no errors. Might be due to the older vehicles using unheated sensors and I think those are much more sensitive to getting good exhaust gas flow. Maybe with the later vehicles and heated sensors, this is less of an issue. But since you can get a Denso sensor for little more money than another brand, I'll stick with a Denso unit.

 

aww... thook is getting emotional?


already said I'm running Bosch O2 sensors in my 91. Two emissions tests later (4 years [once every two years] mind you) and no problems at all .. heck, the truck just passed HC and CO without an operational converter (read as completely 100% burned out, look through it like it was a straight pipe) and likewise remember I'm in California and have to test every other year.
Oh, I already said that? hmm....
okay, I'll go back over here and do over here things.

 

x2 on sparkplugs.com

I got my NGK o2 sensor from them, ngk wires and a denso air filter

 

Awww....are we projecting? We're always emotional......whether it's feeling good or being upset. And, upset I am not..... Just hashing the contrasting ideas out.


4Crawler......my '86 22re is non-heated, also. Chalk it up to the unexplained, I guess.
