I had the sensor unplugged and started my truck. It took a few seconds (about 5 sec) but it eventually started. That mean my ICP is bad?
The ICP for my truck is on the passenger side valve cover behind the alternator, right? My truck is a late 04, so that should be it.

If the truck fires up ICP disconnected and does not fire up ICP connector connected, most likely your ICP sensor is defective. Do not use aftermarket sensors.
Check the pressure with a code reader.

I tried multiple times yesterday to get my truck to not start with icp connected but it fired right up every time. And there isn’t any codes coming up anymore. It’s possible it’s intermittent but I did notice some oil on the connector to the ICP. It’s quite possible it’s out if there is some oil showing.

Then disconnect the connector and clean it with a cleaner for electrical contacts, it is possible that the oil is your problem, I believe less.

All owners of the 6.0L need a quality scan tool and code reader. ForScan is about the best.

Get a scan tool or plan to be a "parts changer".

There wasn’t any oil in the sensor itself so I don’t believe that the sensor is bad, at least I don’t think. But I will clean up the connector and add some dielectric grease and see if I have any issues after that. Thanks!

If there is oil on the connector, then it probably leaked through the sensor. That is just what happens ............... afterall 4000+ psig oil pressure, and where else would it come from?

I had gone to visit my parents who happen to live nearby. Of course, truck didn’t want to start when I was about to leave. These are the codes that came up during the time I tried to start the truck up. I’m most certain that the sensor is bad. I’ve also had the crank sensor code come on before so I have to get that changed out too

A crank sensor code can come from excessive cranks - doesn't necessarily mean that the sensor is bad. That is the kind of thing that we meant when we said it is easy to just be a "parts changer".
