[@d-lowz-no9931]

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 👌🏽

[@anthonyklanke1397]

Awesome! Maybe this has been my problem the whole time :) my car will only start in cold weather, so maybe the temp sensor is reading too hot on normal days and not giving enough fuel!

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?

[@DragonRoyZ]

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.

[@truckinedchannel9982]

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

Thanks! You informed me about new things today!

[@andyl9920]

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.

[@Mike_The_Hog_A_Nator]

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.

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

[@jbobdavis1984]

So what is the issue if my engine runs cool unless I hit 45 to 75 mph with the AC turned off. which at that point the temp gauge runs slightly above the middle of the gauge. If I'm driving around town, I can run ac for about 30 mins, then I Have to switch to vent to keep the temperature gauge below half way. During winter, My temp gauge shows I'm running way too cold. I can't even get up to operating temp in the winter months. During summer if I'm driving without the AC on and not driving on the highway with vent and heat on my engine runs very cool. 😅. Is it my temp sensor ,or do I need to replace radiator, condenser? My coolant fan is mechanical. I have a heater core leak. Because of the heater core leak, I bypassed heater core for summer months. No check engine light. ???

[@johntrovy5528]

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!"

Thanks 👍 great video

[@fernandoguardia3379]

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...

[@Dankcatvacs]

yup happened to me with my 92 subaru loyale , also with a bad tps will do that

[@Grubkiller]

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?

[@Engbader]

[@pedrogadea4926]

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

[@ElPadrino610]

Yes

[@lastman6426]

How?

[@dhalsim-1]

If it reads hotter than it actually is, not only will the gauge reading be too high but it will also reduce fuel potentially stalling the car and preventing warm starts.

[@someone7773]

Does this also make it difficult to use the AC?

[@Buckseed]

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.

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

[@Ricatonniisasavage8854]

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.

[@greatcesarsghost]

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

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?

[@КирилДраганов-р9д]

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!

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.

[@dhalsim-1]

It sounds like an electrical gremlin, I doubt the cluster needs replacing as everything in the cluster usually works off the same fuse. If you can get or borrow a scanner that reads the engine temp as it rises you'll know the sensor is ok if it does.

[@choadcityusa]

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

[@BryanG830]

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.

Would this cause the Catalytic code keep coming up. Runs very good at different speeds, did run a total of 3 bottles of Catoclean. 2 back to back and 3rd one few tanks later, replaced both 02 Sensors and light did go off but came back on about a month later and 3rd ran, and kept doing that every few tanks, put new gas cap on also. Did replace heater hose that was back ordered last winter. Light started to blink on and off in one ride and stayed off so couldn't find out why, replaced heater hose and grommet that antifreeze got on, I figured with reading up. It was that. Went off and stayed off. Then came back on 4 or 5 months later with light coming on full time fora week and off. Bought a cheap scanner to check, got tired of going to parts store for it. Did clear code about 10 times after it came on right away since, it's cleared itself haven't checked the fuel injectors yet, has a brand new tune up from summer before with just 15,000 miles on it max with new coil packs and all parts. a tune-up should be done right and replace old coil.packs too, kept them incase, I'm ready to check all plugs again to see how there burning but 1st check each injector. Then pull spark plugs out. It's due for inspection in March 2023. Want it fixed. I wondering if the ECU can cause this issue? I only spelled somewhat to say rotten egg smell once and wasn't sure if us or car in front. Its 4WD and if punch the gas peddle taking a left onto another street. It will spin the tires and I get off of it soon being 4WD and don't want to break anything in drivetrain. Anyone have any ideas besides changing the Catolectic converter which I plan on replacing both, any preferred brands other than factory parts at those crazy prices. I could shut it off and it may stay off for a month but I won't just because either way, it needs fixing and I just did brakes, tires 2 years ago 80 000 mile Michelin tires and gave it a nice buff job when light stayed off. Anyone with ideas please send them open to listening to other's, its why I replaced stuff for, should of let them fix it. Just not that 1 garage since no place to work on in December and that was my Christmas present $818 charge and said Radiator was shot, not when I checked it out and was taking back but they had ripped apart putting Radiator in because I found it on ebay motors for $73 with shipping.

Cut trans lines to fit it. Not factory that's for certain.

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

[@anthonyklanke1397]

Do you think a faulty temp sensor could lead to a no start problem?

[@envyvezzy21]

Yes crank but won’t cut on fully
