Temp. Gauge Not Working..

[subie]

Hi guys,

my temp. gauge (in the cluster) is not working... so, which one should i look for??

- cluster? how can i tell is the cluster is broken? (everything else working ok) and cluster is in good working condition

- temp. sensor? where is the sensor? how can i tell the problem cause by this sensor? how to change and how much?

Cheers

anyone??

on the top radiator hose inlet on the intake manifold you'll see two sensors, a large one and a small single pin one with blue/black wire, this smaller one is for the cluster, take the wire off, and shove a wire in the spade terminal then earth it out somewhere. Turn the igniton on and the temp gauge should shoot way past the Hot mark... if so, the cluster works fine and the sender in the rad pipe is buggered. If not then the gauge has issues.

btw, dont leave the igniton on for too long with the sender wire earthed out.

Simon-R32 can u explain "take the wire off, and shove a wire in the spade terminal then earth it out somewhere" abit more .. i'm little noob -_-" in technical stuff

cheers

I had the same problem and it turned out my sensor was faulty.

We determined this by earthing the wire out as said above and the cluster needle shot up. Soon as I pulled out the sensor from my other car and put it in this engine the cluster worked immediately.

i had the same problem with mine, found out the wire was loose out of the sensor.

heres a pic of the location if your unsure.

Here is a closeup of the sensor (left)

thanks for the pics guys..

hey Dave.. ur circle was too big mate lol.. which one is it??

[SoFly]

theres only two sensors, not hard to try them out. (only pic i had, hope it helped lol)

ok, i've got it .. a small one

Lol

i understand your a noob and all, but you aint going to find it without going out and having a look yourself lol. I thought i explained it rather well, and with the pics posted, anyone should be able to figure out which one it is

so did you try earthing it out? you might find that the contact on the sensor is dirty and by pulling the terminal on and off and few times it will work.

ok, with all of urs help.. the testing is done!! well, the temp sensor was faulty

now, i have some more questions...

- how much for the sensor from nissan?

i have an after market temp gauge and

- just wondering if i can use the fectory sensor mounting to mount my new sensor that came from my new temp gauge? my new gauge sensor thread is 1/8 ..

-between the factory temp sensor and after market one, are they the same thread?

cheers

[Simon-S14]

as for thread, i have no idea, why not take the sender out and try threading in the new one by hand, if it doesnt go, dont force it as the thread pitch may be different.

otherwise, i cant see a new one being too expensive, you could grab a 2nd hand one from wreakers... or drill out the hole and retap to suit the new sender?

[subie]

thanks mate,

if they using the same thread, do u think is gonna be ok to mount the new sensor into the stock mounting sensor?

cheers

[Simon-S14]

of course

moved to Gen Maint, not a performance issue

Hiya folks... just a quickie noob question- the single pole water temp sender is for the gauge only? the ecu doesn't use this sender? Long story short, if i swap this sender for an after market gauge, it won't throw the ecu into panic mode? :-P Cheers guys n HAPPY NEW YEAR!

My cluster gauge didnt work for a year and I didnt have any problems with the powerfc.

i think the little one (single pin) is for the gauge cluster and the other one (next to it) should be the one that send the signal to the ecu.. correct me if i'm wrong..
