My temp sensor has been acting up every once in a while. The motor and almost everything on it has been updated or replaced (PM mostly) with the exception of the temp sensor and a few other parts. I occasionally get an EGR code and traced back to the temp sensor. This is the last piece on the EGR circuit to be replaced.

My issue is, I can't seem to get one. I have searched all the known distributors I can think of. Toyota parts overstock (lakeland) showed some but after 5 weeks cancelled my order. Ill assume they cant get one but are awaiting their reply to know for sure. I found another at a dealer in Florida and ordered it today. Afterwards, I noticed their email is toyota parts overstock. Sigh

This is the part number in case anyone has an idea 8941260020.
My next thought is adapting one from something else. All I need is to have "X" resistance at "Y" temp.
Worse case is, I remove mine, store it, bypass it and reinstall it when I need to smog it. The other reason to reinstall it will be after disconnecting my battery having it reset my counts.

Opinions or ideas?

What makes you think your issue is the EGR temp sensor? Been discussed
many times on the forum that the temp sensor is rarely if ever the cause
of an EGR code.

What code are you getting and what have you done to fix it?


To answer your question however you can search Rock Auto and Fleebay

(did it for you)

NTK may be the original manufacturer for Toyota. Either way, IME, their parts are high quality. FWIW

Thank you for the reply

Your absolutely correct.
I've been doing drivability professionally since 1980 and I haven't seen one yet. Of course, mine is going to be the first. The resistance is off a bit and has been getting further out as time goes on. The code only use to happen towing on a grade, rarely. Now its normal driving. I was actually thinking of opening up my EGR to increase flow slightly but see no reason to have to modify it.

Thank you for the eBay link. I was looking there yesterday and today. Everything I saw was sold out (Quantity available 0). That one didn't pop up. I didn't think about Rock Auto. I don't normally use them. Somewhere in the back of my mind, I remember something about NTK. Again, thank you for that.

that part is NLA. find a used one.
Sigh.
I'm going to assume you didn't read what I wrote and therefore didn't notice that I already know this. I'm also going to assume you haven't been around "used" parts much. A 26 year old, 300k mileage part is most likely going to put me back to where I'm at or worse.

Would be interesting if you could post up the Ohm numbers you got ie: room temp versus ~300'F.

You do a lot of assuming. If you've ever checked out the discontinued parts thread, then you would have seen that the EGR temp sensor is the latest to fall to the wayside. I understand the age of these vehicles, thanks for doing the math for me. I've seen FZJ's on car-part.com with under 200K miles that are being parted out. Yes, our options are getting limited for certain parts. It does stink. Best of luck finding one. This is a part that rarely fails. Lots of good ones are still out there.

I'm not going to bother reading anything you post from here on out. Your comment was not only unproductive but rude. Now your butt hurt because I called you out on it. I don't "NEED" to read the discontinued thread. I know how to look up parts and have had to do it professionally for decades. If you had any diagnostic skill at all you would know that there is nothing that is flawless and nothing lasts forever. My post did not ask for help diagnosing and if you actually read what I said you would see this.

My testing was done when the code first appeared. I knew I was going to rebuild the engine and replace everything due to age. The temp sensor numbers were "close" to spec. Just before the engine rebuild I tested it again and it was a bit farther out. When the engine was rebuilt I replaced everything except the sensor. This was because I have never seen one fail.

I was hoping this didn't turn into a "diagnostic" thread and I really hoped someone wouldn't derail it. For those who wonder how I tested this, I did it in parallel with the ECU, on my lab scope under a load, on a dyno. Yes, I actually have two floor dynos and a smog dyno at work.

Thank you again to @Kernal for his links.

I bet you do.
Your comment was not only unproductive but rude.
I told you a part is NLA after you stated you tried multiple times to find one. I was trying to save you time and simply inform you.
Now your butt hurt because I called you out on it.
Not sure how one can tell someone is butthurt thru a keyboard ? This is a PG rated forum man. Why would I get "butthurt" from a stupid comment.
I don't "NEED" to read the discontinued thread.
Are you always that grouchy in the morning?
I know how to look up parts and have had to do it professionally for decades.
Congrats.
If you had any diagnostic skill at all you would know
There you go assuming again. I never mentioned anything about diagnosing your issue. Nice assumption.
that there is nothing that is flawless and nothing lasts forever.
Yea no $hit

Opinions or ideas? :rofl:
huh???

You de-railed your own thread faster than a drunk Amtrak conductor :steer:

Impressive but who asked ??

It’s pretty rare to have a bad temp sensor but certainly not impossible, just can’t recall anyone reporting a failure. I’ll assume you’ve already cleaned the carbon off of it. NLA but I wouldn’t hesitate to try a used part if you’re convinced that’s the issue, again because failure is rare. Another option to consider:


And, you guys need to chill a bit.
