Bad ICP Sensor??

when my truck is running and I unplug the ICP sensor it Dies. Does that mean the sensor is good or bad? what test should I run? I thought I read about it sumwhere but I cant find it now. I gotta misfire/sputter @ WOT, just trying to eliminate possibilites.
Thanks

psd

it sounds bad.you might want to change the o-rings on the ipr valve too,if there old.
what the icp is for is to tell the pcm what oil pressure is in the oil rail to feed the injectors.
and the ipr is the valve to feed the oil to the oil rail they work hand in hand to feed the right psi and
the right amount of oil to feed the injectors.

My '96 E350 ran with the ICP sensor unplugged. But there's a number of sensors and all that need to be together to make it all work. I know I ran it with the ICP sensor and the MAP sensor unplugged.

If the ICP sensor is bad, it will usually run better and have less smoke when it is unplugged. Not a guarantee that that is the cure to all the problems, but it is a start. I know the sensor was updated at some point also. (Mine was bad.)
