OK i removed the wiring harness to change the valve covers and when i put everything back on i saw that this broke
i dont know what this is and is it safe without it?
can i be able to find another one with out the whole harness because the wire ripped

thanks

 

It looks like the coolant temp sensor. Dose your temp gage still work.

 

go to the JY and snip a few inches off one of theirs (vg or ve doesn't matter.. on a VG it's near where the #3 plug wire hooks into the distributor) and strip the wires, solder if you can (twist if you can't) and shrinkwrap it.

 

can i drive it?

 

the coolant temp sensor is the one right behind that, with the reddish/orangish colored plastic cover that clips down..

THATS, another coolant sensor of some sort though.. not sure its name is "coolant temp sensor" though

i just checked the FSM, thats the thermal transmitter.
if you wanted to buy a new one, while youre re-wiring it, since its not the sensor itself thats bad, just the wire.. but im bored.. so i just killed time by finding the name of that for no good reason. lol

 

"The Thermal Transmitter is a small thermometer, that reads the coolant temperature and transmits that information to the dash board. This should not be confused with the Coolant Temperature sensor, that sends the coolant temperature to the ECU (cars computer). The Thermal Transmitter should only be replaced if your dash board is showing bad temperature readings."


Id say yes you can drive it..
but dont go blaming me if because you cant monitor your coolant you blow up

 

yeah what he said... the car can be driven but you won't know the temp of the coolant. put the sensor back in before driving b/c i think that it leads to a coolant passage... it does for sure on a VG. so on a vg it'll leak all your coolant out if you remove it. but just get the wiring fixed asap so you don't risk an overheat that you never saw coming.

 

thanks everyone
i just tapped it up temorarily and i see the guage is working on my dash
will go the the junk yard next week

 

Coolant Temperature SENDER is how I call it.
and as long as you put it back in (connected or not) you will be fine mechanically

 

My mistake.

 

You "tapped it up" or "taped" it up?

 

i taped it

 

yea well, the FSM calls it otherwise.. gee, its NO wonder it takes 2 freakin weaks to get a part from you
****?
yes I am, tyvm. lmao..

 

It's most definitely the gauge sender. I just got a new one in the mail yesterday, maybe my gauge will stop dropping off randomly.

 

Won't hurt to have... pretty cheap. But, I hope you tried cleaning the plug and contact first to see if that was it. The one on my Celica got gooey and flaked for a long time... until I got arount to actually looking at it. Clean is good.

 

I recognize that part all too well, I have a shiny new one laying in a plastic bag in the front driver side of my car that I bought for like $10 at autozone when I was worried my car was having overheating problems (sender/transmitter/sensor hasn't worked as long as I've owned it).

 

and i was thinking all da time that it has something to do with car's ground....

 

nope... if it were a ground the wire'd be black, not green, on a 3rd gen maxima at least. green *can* be ground, on some scooters, or in your house's wiring behind the wall. just not here.

 

thanks for info capedcadaver

 

just use a regular electrical connector it will slip over it. just like everyone says controls the gauge on dash. the one next to it is for the ecu. good luck if you go to yard..im sure there is about 10 to 30 3rd gens there. thats how many are at my local junk yards.
