I have an ford e350 cutaway van. Where is the ICP sensor located

ICP doesn't compute.
What does ICP stand for?
What are your symptoms?
Any DTCs?

Injection Control Pressure (ICP) Sensor. They are normally located where access is limited. Some diesel engines require removing the turbo and other items. I'm not sure in your situation.
