S13 SR20DET Coolant Temperature Sensor

[RSP13-Sideways]

Where is this located? I did a search and came up dead blank, most posts didn't even have replies.

I have a RPS13 Blacktop motor, I believe this unit is causing my ECU to read incorrectly, please let me know where it's located and which one to use.

If I'm not mistakened it's the 91-94 Sentra SE-R or the Z32 right?

[drifter808]

its right above the throttle body and to the right. underneath the first plenum tube and you'll find it. theres two sensors, one has a plug and the other one is a clip like thing. If you need another one i have one for cheap just PM me.

How do I trouble shoot to make sure that it actually works?

You have to use teh correct ECT senor and in the case of teh RWD SR20DET there is more than 1 option:

Here is a list of differnt sesnor part numbers whats its gonna boil down to is the correct sensor for the specific ECU you are running.

Here are some ECU part number along with the years:

Charlie, you're a lifesaver!

Search for that ?. On my KA at 160-170 degrees or so resistance across the sensor should measure around .300 K ohms (dont quote me on that). You can also try cleaning the electrical connection for it, and the sensor itself (mine was pretty dirty and after I cleaned it the car ran better).

So for a 94-96 S13 black top SR with MT, the part number 22630-51E00 or 22630-51E02 would work?

Edit: 22630-51E00 has been replaced by the part number 22630-51E02.

From www.nismoparts.com the 22630-51E02 part costs $21.74, but shipping is $8.95, which is BS.

Courtesy Nissan wants $24.65, and $9.09 for shipping with UPS Ground.

Hey imma bump this old thread in hopes that those pictures can work lol.

I just got the sensor from the dealer but its skinnier than my old one. The skinnier one fits snug and doesnt leak.

Will this cause a malfunction signal to be sent to the ecu?

Just worried since thats only the difference. My engine is sr redtop with ecu 62 btw if that helps.

Edit: 22630-51E02 is the part number that I got from the dealer (skinnier than the original one that i pulled from the engine)

FYI #62 is not good enough, give me your ECU part number and i'll get you the correct ECT sensor it should start with 23710-blahblahblah.

So you are saying that yes, using that smaller ECT will cause a malfunction in my car still correct? If that's the case i'll get you the ECU number in a bit.

Based on what you are saying, I was using the Blacktop ECT instead of the correct redtop ECT? If so i'll post more info and hopefully you lead me to the proper redtop ECT. Thanks man.

There isn't a choice between smaller or bigger there is only 1 ECT sensor the other is a Temperature sender for the gauge cluster.

Just get me the number and i'll help you out.

Here's the Ecu numbers:

62 is the big fat number.

23710 50F00 is the number below it.

A11-000 G90 are the set of values below that. Thanks r34.

Edit: When I say skinnier than old I mean im talking about the new ECT is skinnier than the old ECT. I"m not talking about the sensor for the gauge cluster. That gauge sensor is located to the right of the ECT. Im just saying my old ect probe is has a bigger diameter than my new one. in terms of ECT lenght they are both the same size just old is fat, new is skinny.

Anyways my car problem is that it runs rich and keeps fouling my plugs out. I have new injector o rings and got my injectors serviced by RC engineering so they are flowtested and working. When I pull codes off the ECU, I get 1 long blink and 3 short blinks (error code 13) which is ECT sensor.

I have checked all my harnesses at all locations and the output voltage from the ecu to the harness is 5V per FSM. There is continuity between ground and and the middle plug, so harness check fine. Just stupid ECU keeps throwing 13 code even after resetting it.

23710-50F00 is from 91/01 - 94/01 Manual Trans

The correct ECT sensor is 22630-V5010 from 91/01 - 94/01

Sweet man, I hope it stops throwing code 13 tomorrow. I wonder if the dealer will let me exchange the part haha. I told the dealer it was for 91 sentra and they gave me that other 22630-51E02. :bash:

Thanks again, i'll chime in to let people know for reference, if it works, so redtop users like me can have a reference.

Well for one never trust that you got the correct ECU for your exact engine, ECU get tossed around like dirty whores unless the clip was intact 100% then it is most likely the correct one.

[vegita319]

Well after going to the dealer, 22630-V5010 i superceded with part 22630-51E02. Everytime the part guys at the dealer try to draw up 22630-V5010, the computer would tell him the new part number is 22630-51E02.

Just wanted to put it out there that these are the same now.

I've got an aftermarket electric fan on my s13 red top and I was wondering if it's possible to hook the fan up to the coolant temp sensor so that when the sensor is activated it would turn on the fan. -thanks.

you need a fan controller to do this.
