To the point. no extra talking. Thanks

The key is to keep your cool!

Very helpful. I have 2 of the symptoms (Black smoke and error codes) but the car seems to run pretty much Ok when it reaches operating temperature. The garage is going to change the sensor anyway.

Appreciate it bro! You saved us from getting scammed by a mechanic shop

On older cars it can cause a no start too. My 94 bronco with minimal tech relies on the signal to calculate fuel ratio for operation. If it’s bad and reading too cold, it’ll flood the engine with fuel and if it’s the opposite, it’ll starve the engine of fuel which pretty much cuts the pulse to nothing and there’s nothing to ignite and make it run. Keep that in mind 👌🏽

5/5 stars ! Quick, concise and easy to check 🎉 Thanks for all your help.

Would a bad sensor cause the engine to labor ping? Doesn't do it when engine is cold. Gauge doesn't show it getting hot

Hi, I used to have a bad engine noise. But when I changed the old corroded coolant temp sensor, the noise was gone for about 2 months. It was a temporary sensor, as it was purchased like 3 bucks. I plan to replace it as the noise is starting to come back.

Thanks Brad! Same thing happened to our Yukon. I actually Broke the clip so now have to figure out that repair.

Good vedio had ever problem except over heating. Need to get a new sencer asap

Is it possible for it to have the opposite symptoms if it's reading your car is too hot when it's not causing the fans to stay on always and the gauge to read higher?

Yo man me and my '96 Civic thank you for all this info 👏🏼

I love your videos!!!! You are a great teacher!!! Thanks for all you do👍🏻

Great job I hate when the mention of bad idle is not brought to diy ppls attention

On the way home today I could hear the fans running but temp gauge was reading 175 degrees but by the time I got home it was reading 160 degrees and when I turned off the ignition, the fan would not shut off. The fan ran for several minutes until the engine cooled down and then shut off. Will replace the sensor tomorrow. A big thanks.

Beautifully explained....

My sensors reads… but when I drive the temperature gage drops. There is no help on KZfaq for this! 😢

Need help please. I got a P0128 code for bad thermostat. I replaced it. The check engine light went off assuming because i took off the battery cable while doing the replacment. The light came back on 2 weeks later. Scanned the code and got the same P0128 code. Do i just need to delete it using the OBD2 scanner? No overheat, no leaks, temp is normal and good. Any suggestions? A buddy of mine said it could be bad coolant temp sensor but i didnt get the codes u provided in the video.

Thanks! You informed me about new things today!

It also affects the AC

Would it also cause a/c not to come on ? And gauge not to work ?

Will the sender have anything to do with the fans coming on late? Not the sensor

Thanks had some doubts

Thanks man you have saved me a lot on a couple of my cars 😂

Great info!

can you please give me an idea, my car is opel zafira B 1.6 of 2006 show these codes on the screen p111505 and p111606. after I have changed many parts and the problem continues again, I have changed the temperature sensors in the radiator and in the thermostat, the original thermostat has been changed, the new deposit cap, the water pump. I don't know what to change, I have spent a lot of money but no solution please help me with any idea

In the ford ranger, this same looking sensor is the sending unit to the cluster guage temp meter. The sensor is conical and also by the thermostat.

I got a 2019 fusion 2.5 changed the temp sensor reset the check engine light was doing fine for last 3 weeks now it's back on but not overheating or anything Has ran fine the whole time even before I changed it out just temp sensor and check engine on light temps right in the middle on temp any suggestions thanks

I have an 02' Blazer ZR2. Mine is reading spot on when I look with my scan tool but my gauge is off.. The gauge was just reading correctly a few months ago. The coolant sensor is only a year old. The scan tool shows 197° to 195° & my dash gauge shows 210°. It's running fine & getting sticker mileage at 16mpg in town, which is what the 02' sticker shows.

Would a check engine light always come on?

Hopefully this helps me but this was a great video forsure

Thank you Jeevesus

Thank you so much for this video متشکرم

can a bad ECT sensor wrongly read a temp way higher than reality and cause the engine to shut off?

You forgot to include (as for me is a major sign of issues with said sensor as it has happened twice on different vehicles from different brands) that another and very noticeable symptom is that the vehicle's engine stalls (lightly but noticeably) during acceleration at certain RPM levels when the engine is still cold (like in the mornings), as if the engine being almost out of fuel or having an electrical issue, this disappears once the engine has reached its normal operating temperature but is constant and does not go away (despite no ck might be seen dash-wise or through a scan) until the unit has been replaced...

What if i have the p0115 code, but the car is still running good? No symptoms you mentioned just the code?

Would it make my car say the coolant level is low even tho it's full?

What should the temp be in a 5.3 Vortec engine. Have 2013 suburban tku

Would this cause an engine to not start ? My truck only starts when it's hot outside

Question, I have an 03 GMC Sierra, starts up no problem in the cold but when the engine is warm i get crank no start. I have a p0118 code, could this be the problem?

Could this be why my truck takes forever getting to operating Temp bad sensor

My gauge doesn’t go up it all,I check the thermostat and is good,and I replace the temperature sensor unit and still not working, any thoughts.

Wouldn't the temperature guage have a false reading? Mine reads accurate but the fan doesn't come on

Would a bad sensor Not trigger an engine light and Not cause rich fuel, or bad gas mileage.. Only problem is radiator fans don't come on when engine is hot, only when a/c is on low speed kicks on

Thanks 👍 great video

Would it cause a crank no start on 2003 Chevy blazer 4.3?

Thanks very helpful definitely getting changed now even though I do get great gas mileage I'm steadily trying to better that gas is to much gotta keep up with these old vehicles or they will be junk in a fast rate if that makes sense. Probably got around $6,000 dollars into a 500 dollar truck lmao but I'm happy so f it I just wish insurance would cover me for what I say vehicle is worth I can very easily prove it to 4k for transmission alone whole suspension is brand new just had to replace brake booster now temp gauge and probably next will be the rack and pinion. Since the new booster the brakes work to good can't get used to it lol it might need to go back see what he can do about that turn it down lol.

Good vid bud👍

Can you still drive you vehicle with this issue

Does it make the engine rev high and low at idle? 1990 2.2 toyota

My nissen tiida is overhesting and suddenly turns off of an engine while i'm driving, when i turns on the is running always may be if i can change teperasure sensor it can stop that habit thanks help keep on❤it

PERFECT!

What about water would it operate the same with regular water ?

On my Jetta the fans turn on 190 . Witch dash gauge is normal .replaced top coolant temp sensor .. someone said there's a other sensor on bottom corner of radiator where lower radiator hose is ?? Should I replace this also

i got code P011A, What does this code mean?

On mines it’s saying engine is hot while AC is off.. what could that be but car is not running hot and the fan comes on

Bro, I just changed the Thermostat, and Engine coolant temperature on my 2015 Grand Cherokee. The dealer says it's normal for the gauge to not be in the middle since it's old. I am like WTH? it's eating up fuel like crazy and no hot air coming out.. any other clues as to what it might be?

Thanks bro. Good one

Other symptoms are cold hard starts, long crank intervals before starting also the temperature gauge might not work at all it will be stuck at cold even when the car has been running for 10 minutes

nice thanks

My Chrysler 200s fan stays on after turning off the engine and removing my keys, replaced the thermostat 4 months ago and it stopped and the check engine light went off. So I wonder if it’s the sensor, but no check engine light is on this time🤷🏻‍♂️ checked fuses/relays. Everything looks fine but fan stays on

My vehicle starts fine, like literally starts right up cold, but after I run it for say 30 mins and shut the vehicle off, then let it sit for 15-20 minutes, then jump back in it to start, it’s like it starts hard or delay starts when it’s hott. That leads me to not believe it’s the Cam Sensor or Crank Sensor. It’s leading me to believe it’s a Temp Sensor, especially based on research and evidence I’ve seen. Could this be the case or could it be something more severe?? Thanks.

Hello, help pleased! My fans work when I unplugged the sensor, but they won't work when I turn on my ac, could this still be just the sensor?

Is it possible rewire a 2 pin connector in place of the the old 4 pin connector? Because I can only find a 2 pin temperature sensor. I can’t find a 4 pin temp sensor anywhere for my car. 1993 Chevy corsica. If you have any advice I’d greatly appreciate it. Thank you

would it also cause the ac system to not put out heat?

So I have a 2003 Mercedes’ slk230 car starts and runs, when the engine is warmed up under 1k idle I go out for a drive. After the drive, park it and turn it off to go out for 15-20 minutes, and start the car again, but it was stall but still turn over. Could the sensor be out and fuel not be deliver properly

I turned my 2018 hyundai tucson sport off and came back outside 3hrs later and my fan was running? Can you help?

I replaced the cooling fan relays and the cooling fan fuses and I replace the cooling fan itself and cooling fan works and turns on and coolsbthe engine and the AC is ice cold. However as soon as I turn on my car or when the car is idling once i park it, that's when the AC is not cold the fans aren't spinning. And I just replaced the fan the fuse and the relays. Also replaced the thermostat too. And the only thing I have not changed was the engine coolant temperature sensor. Ben still the fans still spin and the AC still gets cold but once I hit the throttle or gas pedal. I noticed every time the engine misfires while idling, that's when the fans don't spin and the AC is not cold. What the hell is wrong with my car? The check engine light is on but it's only reading one code.

Thank u😁

Very good informative video. Thanks for sharing. Helped to cover the thermostat part. i have 2010 ML550, just wanted to know where exactly this sensor is located? If i can have a diagram or picture to locate it so that i can replace it. Appreciate your help!"

Would this help with a p1217 on a Infiniti?

Will ect make one won't idea

So my ac stop working the fans stay on after I turn car off and the heat gauge is stuck at C Any advice???

If my coolant temp sensor is bad will the temp in the dash also reflect that?

What if the fans continue to run? Is the sensor still the issue? Run with car off and key out. I've changed relays and check coolant levels. Fan still continues to run.

Hello, my car is a fiat bravo 2 2008 1.6 multijet diesel. Since I have it from the last summer the car does not have a stable idle. In the winter that problem was gone. This summer it is here again. I tried a lot of things but nothing is helping. Now I have error codes P01EA and P0487(for EGR). P01EA looks like very generic code but it looks like the ones for engine coolant problems. So I am thinking is it possible for a faulty coolant temperature sensor to cause an unstable idle when the car is warming and hot? For example, maybe the coolant temperature sensor is sending wrong information to the ECU that the car is still cold and the ECU is pushing the wrong air-fuel mixture as if the car is cold? Thanks in advance!

Can it be bad without a trouble code?

Thanks for your videos but my car When its hot the fan not working on high speed Just working on low speed So my car get over heated

Hi bro, when i start my car for the first time in the morning , car start bud immidiatly die. After second start car everithing is good. I changed coil, cable, spark plug. Is coolant temp. senzor could cause this ptoblem? Thanks

my car recently has super low rpms & the tempature meter moves up & down & poor mpg

What about it not heating up needle barely rises off of cold

Great vid Appreciate it!! 👏👏👍

👍😠👍you are awesome thanks.

2000 mercury cougar. V6 engine temp fluctuates up and down. Gets very close to red but no weird smoke coming out from pipe. When i get past 3k rpm it feels kinda like a chug. Any possibility the temp sensor is bad? It does this intermittently. No leaks, engine light IS on, and getting somewhat bad mileage. AC blows ice cold and heat blows hot.

What if my fans come on when the engine is cold and stays runing

Whats and estimate cost to repair? I have a 2004 Hyundai Accent

i would like to know, the new ect won't turn the on ac; it says the engine is hot a/c off

Ty

Would this also contribute to not getting heat out of the interior vents?

My temp gauge doesnt work now after mechanic replaced ect and thermostat, is the new ect bad or did the cluster get fried? everything else works on the cluster though. He said it will cost 500 bucks to replace cluster.

Not every car turns on the fan at 200°, most turn it on around 170-195°

Temperature is on Red but is not overheating on my 01 odyssey.. everything seems normal, no black smokes, but I also failed safety from rotted frame.. she's toast

97 Chevrolet s10 pickup. It starts, fan turns on, idles fine, heater works, cool air works, but after ten minutes the temperature guage starts goin red. Shut it off, sits two minutes, turn it on and it goes back into red. Ok check hose. Hose is not over heated. What is happening? I'm new so I really have no idea. If anybody sees this, you know more than I do so please tell me your ideas. Thank you.

My car fans won't come on when engine warms up. When I turn on the AC, the radiator fans turn on.

Is that a pic of a sender ? Not a sensor?

Oh but sometimes the thermostat is at the top radiator hose

Can it cause my car to sputter at higher speeds ?

I have a 2000 accord 4cyl and both fans won’t turn on even when I turn the A\C on, would that be the temperature sensor or would it be the thermostat? Btw no check engine light on
