Good Evening

I believe i have a wiring issue , with in th engine wiring loom.
as the ICV is not receiving enough volts to operate properly . ( not fully open with stone cold engine )

has anyone had a similar problem with the wiring and what tests should i perform.
I am working out how to do " voltage drop test " at the moment and believe this is the way to proceed as it would identified any unwanted resistance in the circuit.


thanks in advance. any experience would be welcome.
