Because, there is everything.

The point of sadman was to show how to use tracking regulator. The rest is up to the experienced designer.

1: +5 for sensor
2: main position feedback
3: backup position feedback
4: ground

5: 12 v motor drive
6: 12 v motor drive

Note the type of motor is like the ones in printers only two wires to drive the print head.
position sensor feedback for head position. 

Ok. We would use a PWM signal ...probably at 1 Khz ( the PWM freq will be determined by the time constant of the DC motor).
I think that i need to use a PWM freq of 20 Khz ( got it from Utube videos)  to determine the speed of rotation....

It must be the voltage feed from the main fuse. ie. 12v

Yes ... this is it. Now i am able to comprehend the whole picture Smiley. The throttle actuator motor is not a stepper motor but a normal DC motor driven either thru a half or full bridge circuit inside the ECM. The six pin connector has two wires for +12VDC, one each for the main & stdby throttle plate sensor and a pair for the +5V/Gnd supply.... Perfect......

Hi,
  While looking at the schematics, it is mentioned that the +12 V supply to the Control motor will be pulsed. Does it mean that i have to use a PWM signal for controlling the motor?. Because i read somewhere, that the motor used in the ETC is a BLDC instead of a brushed DC motor and would need a PWM signal for precise positioning?

One limit this power supply output limited to less then 20V

All the best

Bobi

share design is for reference it can be easily modified up-to 30 volts in those days i am working on good LAB power supply with CC/CV mode and microcontroller controlled
