Nice explanation Ramon of a typical thermistor circuit. The only thing that might be a little misleading is the voltmeter you drew across the pullup resistor implies that the PCM is looking at the voltage drop across this resistor. The PCM is looking at the voltage drop across the thermistor which means you just need to show the voltmeter across it. You just need to show one of the voltmeter leads referenced to ground. Also, this analog voltage being measured by the PCM across the thermistor is fed to an A/D converter where the CPU can use its binary value. Good work and have a happy holidays!
stuzman Sorry for mistake I made. Thank you for explanation sir it does make sense. I hope that rest of this is good. Thank you so much for being part of my channel and sharing your knowledge with us. Cheers
Ha ha have you been watching my Video🤣🤣🤣. Great work! Explained very detailed! Keep the videos comming in 2018! Merry Christmas and a happy and healthy new year, to you, your family and of course al your subcribers!
I thought the same thing to ha ha when i saw the white board . KY thanks for the vid well explained and yours to Dan. happy xmas all have a great holiday
DiagnoseDan happy holidays guys. Your last video inspired me to do this one. You are awesome teacher. I watched every video on your channel sir. Sharing knowledge is priceless . Thank you so much for your time and hard work. Cheers
p0117 and p0118 if you have these codes scan ecm and if it happens at 178f it is bad ecm . computer changes scale at 178 . i have replaced a few for this problem . watch your graph at that temp
Please help I have a 2009 Toyota Camry and I changed the thermostat because it was blowing cold. It gave me heat for maybe half hour and begin to go back to cold. My check engine came on for the coolant sensor. I replaced that and it seems as if the car is running worse. Any suggestions?
I have a 1999 Ford f350 V10 with a po118 po117 codes I've replaced coolant sensor 3 times and pcm 2 times I'm going to rewire it even though the wiring is perfect any ideas
Does p118 cause the car to stall when starting? I need to step on gas to start . I’m thinking it’s my injectors or fuel pump but the check engine light comes on p118.
this is the best explanation I've seen so far, but can someone explain to me why my ect has 3 prongs instead of 2? i cant find what the difference is or what the readings should be.
@@kyhomegarage3430 i did all the testing . And at the end . I found out that the pins in the plug are loose and too wide . So i tightened them up and all worked great .
Thank you for your contribution, excellent diagnosis, Thanks again
EXTREMELY BENEFITED TO A COUPLE OF YOUR VIDEOS .AM AN AUTO TECHINICIAN/LECTURER. NEED MORE. THANKS
13:40 he gets to p0117 if that was the one u wanted :)
Thank youuuuy
Nice to hear a clear explanation, good effort.
spelunkerd Thank you sir . Cheers
Great explanation Ramon! Thanks for taking the time to make this!
White Tiger thank you my friend. I am glad this was useful. Cheers
Well illustrated diagnostic practical video on thermistor circuits.
Tom OConnor Thank you my friend. Cheers
gracias por todo and happy new year from south florida HATU SATI ONE HEART ONE WORLD
juan rodriguez Happy holidays my friend. Cheers 😃😃

Thanks man my sensor failed completely, got a real rough idle and stalled. Hopefully i can replace the sensor and fix the issue
Wonderful video! Thanks so much!

Great Lesson

i don't know how to say thank you it was amazing and helpful. good job

Clean your throttle plate first
I have the p0117 and a p0128.
The car is running cold all the time. Could this be the thermostat stuck open or the ect?
Surge P You need to check wiring firs as was explain in this video. If wiring is OK change ECT
I'm having the same problem on my 2004 gmc Sierra could it be my wires to long
this is the best explanation I've seen so far, but can someone explain to me why my ect has 3 prongs instead of 2?
i cant find what the difference is or what the readings should be.
Power ground and 5v reference
I am having the P0117 on a mini cooper still after having replacing the sensor.
Missed you in the Christmas Special.
rusco321 I know sorry. Will do next year. Cheers
Mine ECT is new . But it reads -40 . With a code p0118 . So os the new ECT damaged ?
EA. jam you have an open circuit. Open sensor open signal wire or open ground wire. You need to test it as I explain in this video. Thank you
@@kyhomegarage3430 i did all the testing . And at the end . I found out that the pins in the plug are loose and too wide . So i tightened them up and all worked great .
EA. jam awesome I am glad you got it fixed.👍
@@kyhomegarage3430 thank you . You give me a lot of information that i didnt know .
