Hello everyone , I need to replace the engine coolant temperature switch located at the back of the 3vze I found an oem Toyota one for a $100.00 from the dealer but my local autozone has it for $33.00 I usually always stick to all oem on my truck but I'm wondering if it really matters on this switch especially when the one at the dealer is the last one in the nation ! , any opinions welcomed thanks.

 

You know what everyone's gonna tell you! Get the one at the dealer. If the one you have now lasted 25+years so will the next oem one. After market switches in my eyes are always a gamble. They could last just as long as oem, maybe even longer in rare cases, but most likely you'll be back to autozone in the next year or two.

So if you can afford it, buy oem. If you can't, autozone works just fine to get you by until the time is right to buy oem... Just my opinion. I've never once regretted buying and OEM part... On the other hand I very often regret not going OEM.

 

I've had no problems at all with Autozone (or Napa or O'Reilly) parts. I'm sure someone somewhere has actually received a bad part (I've even had minor problems with my otherwise excellent Dealer), but I doubt that's common. And what if the $33 part only lasted 10 years instead of 25? Do you really think that truck is going to be your DD when it's 35 years old?

Of course, no one ever really regretted going OEM (at least if you overlook price). So if OEM is what you really want, consider $55 (plus about $10-12 shipping) instead: http://www.toyotapartsoverstock.com/...942220010.html

Or, if you're willing to take a chance on a VERY aftermarket part (and you've got some time to kill, how about $10? http://www.ebay.com/itm/like/370977073958?lpid=82&chn=ps

 

Why is it these parts people need to go all dramatic and say it is the only part left in the country.

I think I have a Coolant temp sensor from Napa in my 3.4 so far so good about 2 or 3 years.

 

CTS are stupid simple. Get the aftermarket one. Hell I use Bosch universal o2 sensors that work great. Really kills the OEM circlejerk when I bring it up.

 

I haven't read about aftermarket coolant sensors not working correctly. I think the o2 sensor is the one where people preach Toyota dealer part.

 

And I've been using a "STANDARD MOTOR PRODUCTS" O2 sensor for the past 7 years without problems. (though I, like everyone else, am a sample of one, so feel free to weigh the other voices).

 

Like an idiot I just had to comment on this...

Driving home last night the check engine light came on.
I checked it and Oh yea lucky me...

Code 21 =
OXYGEN SENSOR SIGNAL/OXYGEN SENSOR HEATER SIGNAL
OPEN OR SHORT IN OXYGEN SENSOR OR OXYGEN SENSOR SIGNAL



I swear this truck hates me, I'm already broke and still have a list of repairs to make. Vacuum leak, leaking water pump, Vehicle Speed Sensor, now the o2 sensor

Purchasing a new one will hurt me more than I'd like to admit.
Anybody have a good used one for a 2WD 91 22R-E they want to get rid of? I can pay but not a ton. I do not own a California spec truck.

I've also never found the exhausts still in the trucks at the salvage yards around here so that's a no go.

 

RockAuto has a slew of O2 sensors (even Denso) for less than $50; you couldn't get me to set foot in a junkyard just to try to beat that. Particularly on a sensor.

DO stick your head under the truck first. Your code is for an interrupted heater circuit. Could be a burned out heater in the sensor, or could be a broken wire. The wiring for the O2 sensor is somewhat vulnerable.

 

I doubt it's the wire because that code had gone off once before and I just pulled the fuse and cleared the codes. It hasn't showed it's ugly face for several months. I think if it was a wire problem it would probably show up again almost immediately.

True?

 

Why?

If you had a table lamp that went out, but when you shook it, it came back on, would you suspect the bulb or wiring?

I don't really know how likely the heater filament in an O2 sensor is to burn out, or re-connect. But if I dropped $50 on a replacement sensor, and when it came time to install it I immediately saw a dangling wire, well, I would feel sad. All I'm suggesting is that you might want to just "look" first.

 

Yea I get it. My head is just not in a good place right now,
trying to stay positive though.

 

Just looked all around the exhaust and I could only find one before the Cat.
The wires look like they're still attached to factory mounting points and the factory sheathing is in good shape. Nothing disturbed by debris that could rip or damage them.

Definitely looks like it's never been changed. Just under 160,000 on the odometer.

 

I've got one laying around that's good. Just replaced because of preventative maintenance. I'm in WA tho.

 

Thank's for the offer!

If it's from your 87 4Runner I don't think it'll work.
Denso says pt# 234-1056 for yours and 234-4051 for mine.

Toyota part number on mine calls for a 89465-39285

 

I pulled the fuse again and reset the codes. Went to find out about a job and made about a 25 mile round trip.
The Check Engine Light stayed off but it's probably only a matter of time. It's gotta be part of why I'm not getting the best MPG out'a this thing.
The vacuum leak sure doesn't help... Simply can't afford to fix this stuff till I have money coming in again.

 

The one I need is 89428-14070 but thanks i found the last oem one in the nation

 

Try and locate this part number 89428-14070 if you find it oem from Toyota and in stock I will Paypal you 20 bucks bet you can't , cause I bought the last one in the nation sure I could of bought one from Autozone but I prefer oem on my yota. And its not a coolant temp sensor its a engine coolant temp switch

 

Found and went oem

 

What kind of proof would you like to see.

Toyota Dealers stock very few parts except for items used every day most other parts come out of the distribution centers .

Then myself I very seldom pull parts out of inventory just have them ordered in.

Moot point really I have just heard that said so many times over the last few years .
