ICP testing

Besides unplugging the ICP while it's in place, is there a way to test the ICP while it's out of the truck with a VO meter?

Thanks

Maybe this will help:
You can check the IPC sensor in the truck KOEO
Diesconnect the GPR or wait till it cycles off

Wiring Check:
Measure voltage between VREF Pin B and battery ground.
Is voltage reading 5v ±.5?
Yes=OK
No= Repair wiring

Measure voltage between VREF Pin B and signal return Pin A.
Is voltage reading 5v ±0.5?
Yes=OK
No= Repair wiring

This is Measured KOER

Thanks Cuda, I'll check all that when I get back from the kids ball game. quick question, if you can hear the the injectors clicking when the motor is turning over, does that mean there should be sufficent oil pressure in the HPO side of things?
Thanks

Rick, All that means is the IDM is firing the injectors. That doesn't mean the HPO is getting to them. The IPC and IPR control the pressure if the HPOP is producing pressure.

I don't ever remember hearing the clicking of the injectors till today. I pulled the front oil rail plug on the right side and the ICP to bleed off some air. Thats when I was asking about testing the ICP. I went ahead and put it back together before any responses but left the ICP unplugged, and thats when I started hearing the injectors clicking. assuming there is enough oil pressure and fuel in the bowl, what else should I check / try?
