pid identification

[william]

I'm not sure what the two pids I highlighted in the screenshot monitor, I think they are pressure control valve and volume control valve for the high pressure pump.
Could someone confirm or correct my guess.
cheers.

Yes you are right.

PCV PWM - pressure control valve pulse-width modulation duty cycle - a signal that module sends to PCV.

VCV PWM - volume control valve pulse-width modulation duty cycle

The term duty cycle describes the proportion of 'on' time to the regular interval or 'period' of time; a low duty cycle corresponds to low power, because the power is off for most of the time. Duty cycle is expressed in percent, 100% being fully on.

We will correct the descriptions in our database to make it more informative.

Thanks for the confirmation and info about duty cycle, seems there's a few controls on the mondeo that use duty cycle.
