Thank you so much for showing how to trouble shoot the thermal sensor. I'm hoping if you can show us how what is the original electrical diagram or connection of the cooling system. My corolla bigbody 4afe cooling system is always turning on whenever I on the car.
I just bought a 96' Paseo today!😁 I'm stoked! But the guy says that the fan dont work sometimes. I'm going to try this test and go from there. He installed a new radiator.
i have the same problem my camry is keep on overheating because my fan is not working and if i unplug my sensor cable the fas is working. i need your help what is the problem
Thanks for the video. Both my radiator fan as well as the condenser fan is rotating when i put ignition is on. Is this also due to the sensor being bad? Thanks
This test does not test if the temperature sensor itself right? You just assume the sensor works and test if the switch works and other circuits are connected.
I did the test and the fan doesnt work. I tested the fan with the battery and it is working If i plug to battery. I changed fan relay and sensor. I dont know if it is a wiring isssue.
I have a couple questions & I really need a professional’s help! So I hired a couple guys to work on my 2001 Toyota Camry & they were trying to change my thermostat & they ended up breaking a sensor inside that tells me when my car is getting hot so instead of replacing the sensor they broke they just put it back in- not working- & now my radiator fan won’t work at all! What did they do to my car?? I’m desperate as I need to work & this has made my job very difficult due to having a cleaning business I can’t get to my contracts & this vehicle is my work vehicle. Is there anything you could suggest that will help? I know how amazing you are w cars trucks etc so I’m very much interested in what you’d have to say! Please you are my last Hail Mary! 😂I hope to hear back from you! Thanks 😊 Carebear 💜
Hi Peter. Tried the fan sensor test as you have shown on my 1997 corolla and the fan does not rotate. If I pull the fan rely out and reinstall it the fan comes on momentarily an stops when the relay is seated. The engine does overheat and I never hear the fan come on. What do you suppose is the problem?
plz help my car fan turns on but late it don't turn on when it suppose to it only turns on when it's hotter than normal I already change the thermostat but still doing the same thing
Hey what's up brother?I have a 93 Camry LE. I did the test with the sensor but the fan did not turn on, but when I disconnected the driver side fan both fan started running. so now I am trying to find out if it id the sensor or the fan relay. what do you think bro?
Hello. I have a toyota corolla 1993 and the fan doesnt turn on when the car starts to get hot. is this because the temp sensor needs to be replace or is it the fan sensor itself?
I have this same problem with a 94 corolla. I unplug the sensor and the fan runs. I turn the ac on and the fan runs. The car gets hot and the fan does not run. I replaced the coolant sensor already, I checked the fan relay for continuity and it was good. I belive this fan sensor might be the problem but I'm not sure. If not then maybe a fuse but my fuses look good. They have been checked for continuity as well.
So what's your answer if you replace that engine coolant temperature sensor, and it's still the same problem ? Still no fans. Fans only come on when you unplug the sensor. Even with a new sensor. Same problem.
@@sandravossen7029 Hi Sandra . How's your morning going ? Sorry to hear you're having the same problem. Unfortunately, I have talked to various mechanics. One mechanic wants $250 just to look at it. Looking at it on RUclips videos. One video clip was saying ; You Might have a car computer problem. If you do have a computer problem, Looks like the computer and the sensor are not talking to each other. and you don't know what you're doing, don't touch it. You might ruin the computer. Right now your car starts. You mess with your car computer, your car might not start anymore. I will keep looking. Or if you find the answer. Let me know as well. Thank you for responding.
Hi Peter, I have a 94 Celica with the same engine. When I unplugg this connector the fan goes on. But When the car is getting to operating tempratures the fun does not come on. My car is not overheating, but I just find it strange I never see my fan come on. Do you maybe have an idea? Keep up the good work!
My 97 Corolla has two fans. One is in the front passenger side of the radiator, and the other is on the back (engine side) of the radiator, on the driver side. When I run the car and it gets hot, the fan on the front passenger side kicks on, but the one on the driver/engine side does not turn on. Should they both be on at the same time? If so I assume that indicates a failed fan right? The power is connected. I just replaced the radiator. I'm wondering if there is another condition that causes this second fan to start. Thanks.
Peter Finn Ok. Sounds like I have one bad fan. I should have tested that and replaced it while I had the radiator out but I did not notice it wasn't working since the car wasn't running when I got to it. It's my son's car. Hopefully I can replace it without taking out the radiator. Thanks for the reply.
Ed Ferguson some cars that have two fans one is to cool down the temperature other fan is for the ac condenser it will turn on right when you turn your ac on
Roy Bell I will unplug the fan from the temperature sensor to see if it kicks on, so I know it is working. I have not seen it kicks on due to engine temperature yet, however it is not overheating either. Thanks.
night doge it sounds like the temperature sensor on the thermostat housing is bad. That would be why the fan on the left side works when you unplug it. It's also possible the relay is bad. As far as the AC fan, it should turn on whenever you run the air conditioner. If it's not, I assume you have a bad fan motor there. However you might want to do some research to see if there's a relay for that one as well.
I didn't understand this tutorial, most of the time it's crystal clear
Thanks for comment 😀👍
hey peter, thanks man. i will replace my sensor. your video confirms my mechanic's troubleshooting steps.
Glad it helped 👍

awesome thanks man nice simple test for the sensor operation
Thanks Sir. :-)

Yes, the sensor or cable is loosen
This test does not test if the temperature sensor itself right? You just assume the sensor works and test if the switch works and other circuits are connected.
excellent job friend
Thank you! Cheers!
Thank you. You're the man!
Thanks for info Sir. :-)
thanks for the info.
Thanks for comment. :-)
Peter Fin my toyota corroll fan allways running when i turn on engine before it was running automatic whats the problem
all good Peter, thank you ...
Thanks for Great comments.
I did the test and the fan doesnt work. I tested the fan with the battery and it is working If i plug to battery. I changed fan relay and sensor. I dont know if it is a wiring isssue.
Hi
This means that the sensor is not working? thanks.
Yes

I didn't know Dracula liked to work on cars
Yes
If the wire plug in my sensor is one hot wire how can I test sensor to know it is bad one and I should change it? Please help.
But is the fan blowing or pulling
My fan is never turning on. Can it be the sensor or is it the fan itself? Thank you
Fan works only in HOT temp
Hi, I removed my plug but the fan does not go on. Is it my sensor, relay fuse or thermostat that is the problem? Thanks
Let me check

Sounds like the Relay needs replacing if I understand your description ... if when sensor is removed the fan did NOT go on ... yes?
plz help my car fan turns on but late it don't turn on when it suppose to it only turns on when it's hotter than normal I already change the thermostat but still doing the same thing
Hi, you need to replace temp sensor in engine.
Peter Finn yes
Sir the fan is still not turning on despite l have changed the sensor. Pls help.
This sensor good or bad
I have the same car... Once i do the test shown in the video the fan dose not turn on.. and i dont have that small fuse box.. do i need it?
Noted 👍
Any advice?
I have a 99 prizm. I can't find the sensor where you say it is. Could it be in a different place?
Maybe you don't have it ?

Hi, I bet for relay.
What is the radiator fan sensor part code?? i have toyota corolla 4efe engine i cant find it
Good comment 👍
thank you
You are welcome.
Peter Finn its work
👍
Hi My 2006 Corolla filling fan keep on and off instantly even the engine is hot!!! What happen? Please answer me.
Temp sensor is bad or coolant loss
How long is the fan supposed to be on?
Thanks and noted 😊👍
when i unplug my sensor it still does not work
sensor is not working

check your fuses, fan relays, then check the wiring
