Hello! My sensor is new( hella) and at cold water resistanse is low and at hot water resistence is high...is opposite that you describe...what s the probleme? I test another sensor new, and the same store
My temperature keeps jumping up and down with barely pressing the gas. I have no codes and replaced a sensor already. Do you think its the wiring to the sensor?
Most likely engine you have some air trapper inside the cooling jacket. I would bleed air from cooling system then check ECT sensor wiring integrity then olnly replace temp sensor.
ECU itself fails very rare, most likely you have wiring to the ETS or wiring down to the sensor, defective sensor or issue with power and ground to the ECU. What vehicle do you troubleshot?
@@PistonShack 2009 volvo c30 T5, i’m suffering from this problem When i use vida and force fan to run its running and sending You may be right wiring problem, what do you suggest? Thanks
@@geoepi321975 Hi brotha! What kinda vehicle do you have? I would check: -continuity and resistance at the cooling fan motor; -ground and power to the motor; -check load and control sides of the fan relay if power is missing; - control side signal, check 5v ref at the sensor, unplug sensor (thermistor) Let me know if you have any questions. Cheers)
While your video is ok... but in your teaching, you never explained which wire is your ground. What do we do when we have dummies like me out here ? Also, #5, you only test the ground wire ( which ever one that was ), So I would assume you do the same thing with the other wire.
Hey Martin. It doesn't really matter. One of the wires will be GROUND. It depends from circuit design of your vehicle. You can determent which wire which or just check wiring diagram. But thank for sharing your point! Cheers.
Your voice goes up and down. I’m guessing English isn’t your native tongue. Being from the southern US you are killing me. I’m not saying I am any better and I can barely speak Spanish. So, you’re knowledge of the English language is extensive but OMG you’re killing me man.
Can you change the way you talk dumbass? If you don't like the way he talks don't watch his videos simple as that. You think everyone likes your southern twang? How can you possibly expect him to change his accent you moron? You are one dumbass southerner.
"We did it. We did it together" Haha... Thanks for building unity with the viewer. *Suscribed*
Excellent video…the best one I have ever seen about testing a coolant sensor
Glad it helped Jose! What vehicle ETS are your testing?
The best video I've seen about the temperature sensor. thanks a lot
Thanks a lot brother for your feedback!
Thanks for this video, it helps me to fix problem on opel.
Awesome tutorial! 👍🏼👍🏼👍🏼👍🏼
Thank you Tony! Cheers!
hi ,
I wonder if you could explain what to do if I fail in any of 5 tests and what does it mean.
thanks
Hey Ahmad! Well, it depends what test your ECT failed it will give you direction to do future diagnostics. Which one you failed?
I thought when you test for ground , you hook the multimeter from the ground wire to the ground side of the battery?
What caused the P0115 code during your test? Tnx
Faulty ECT sensor thrown DTC.
because in my vehicle it has 12 volts in the connector of the sensor ect? Ford f150 1998 v6 4.2 .... Thanks

@@PistonShack thanks. I will check wiring tomorrow and try to bleed it again.
@@PistonShack yup there was a short to ground in the connector.
do you need to turn the key to ON position for continuity test?
No, you don't have to turn key ON for the continuity test.
@@PistonShack Thank you sir
@@PistonShack Sir does the CTS has polarity?
Awesome video my friend 👍👍
Thank you 👍Robert!
Great job, thanks!
Hi,
What if there is a problem that ecu do not send signal ?
ECU itself fails very rare, most likely you have wiring to the ETS or wiring down to the sensor, defective sensor or issue with power and ground to the ECU. What vehicle do you troubleshot?

You may be right wiring problem, what do you suggest?
Thanks
@@PistonShack 2009 volvo c30 t5,
Daah!!! Well then you have a possible issue with the ECM or it's circuitry or both, it's not rocket science you moron.
What's the reason if signal wire shows 5v or more v?
How high is your voltage readings?
All tested ok. Replaced sensor and cooling T-stat and I am still getting P0115! Don't know why??
Hi Rakesh, well what is a resistance on a temp sensor when engine is hot. Could be defective sensor.
@@PistonShack I have no idea! But my temp gauge is right in the middle and I have good heat now!
@@Rockysvideostation Seems you nailed it down.
@@PistonShack Ya but my engine light still on!
@@Rockysvideostation Did you clear code from ECU already?
Thanks
You Are Very Welcome Balson!
At open reference I have 12 volts is this normal
12 volts at reference wire circuit tells about poor ground at the sensor or ecu shared ground. Sorry for late reply.
Bad ECU ground will raise voltage on all 5v reference circuits. 5v ref is a blood life of engine computer.
@@PistonShack hi I Am sorry I have 12 volts at thermal switch, and 5 volts at sensor itself but fan is not engaging
@@geoepi321975 Hi brotha!

I would check:
-continuity and resistance at the cooling fan motor;

You're welcome Mark!
Nice video thanks
You are very welcome, Hayder! Thanks for the interest to my vids.

TEST nr. 2 what you're connecting to what?????? very lousy info.

Thanks for watching John!
That's interesting to know other people opinion and impression)

What are you saying ??
Good point. Thanks for 👀
