This is interesting bit banging, can look at adding this in as a 100hz or 10hz pump PWM functionality that can use PWM channels or normal outputs.

Some of this Pumps need an external pull-up to 5V. The script is running in my car. I didn’t wanted to interfere with other stuff in the firmware as PWM Pins can’t be accessed by gpio matrix. Open to do for me is still to also read in the PWM answer of the pump.

the struggle is real

gents, for the life of me I just can't seem to be able to control the speed of any of these GS450h/Camry/Altima EV coolant pumps using this PWM controller, it's either full speed at 100% and 100 hertz or nothing
