The solenoid is the component on the engine that the connector plugs into. I am using the pins to probe into the connector and touch the terminals so we can measure the voltage on the wires. This particular solenoid is turned on and off very rapidly by the computer in the car, and we are measuring the duty cycle (percentage of on-time) of that circuit.
What do you call SUBSTANTIAL and INTELLECTUAL AND PRODIGY add one more KNOWLEDGEABLE My teacher Justin Miller Thank you very much helpful video SUBSTANTIAL Justin Miller From Nick Ayivor from London England UK 🇬🇧
its handy as u are measuring a control signal or a pulsed output, u can hav PWM over PWM as well, one can be low voltage signal while other is voltage driving a motor, basically it all originated from a 555 timer in the PCM.
Very KNOWLEDGEABLE
Thank you for sharing with us great video
God bless you

engine sounds knackered
That car needed some serious work! You guys probably made a fortune off that thing!
Educational, thank you
In tank fuel pump and engine cooling fan can also be PWM over PWM , so PCM pwm signal driving a module w/pw modulation powering a motor
What that selector on
You need multimeter with high frequency for measuring duty cycle when motor is idle 😁
Great video- Where did you get those backprobe pins? Mine are super thin and bend easily. The ones you are using look stronger.
I don't remember - maybe Amazon or Wal-mart? They're pretty easy to come by.
is there any cheaper variant?
Are you calling those needles solenoids? Or the car part? Please let me know - complete noob here. Cheers!

Thank you kindly, for replying. Cheers mate!
Nice

Too bad my cheapo meter doesn't have that.
Sorry but a stupid question. Why is this important and what are the applicable areas?
Doesn't he answer your question? He gives 3 examples 0:18

You guys ever hear of NEUTRAL? 🤣
This system on this particular vehicle only activates when the transmission is in drive and the engine rpm is above 2000.
