ICP question

[justinlogue5_0]

I have been doing some reading on here and I am a little confused about the ICP sensor. How will the truck act if it is bad or going bad? When you say it is full of oil or has oil in it its bad. Oil in where?? Thanks

Oil in the sensor where the elect plug goes. I just noticed mine has oil all around it, haven't unplugged it yet but that's the only place that looks like oil is coming from. One question is will oil come out of the rail when I remove ICP sensor to replace it?

Overall, I'd say poor driveability, maybe surging or loss of power at higher rpms, often the idle will wander.

Sometimes it's hard to tell where oil is coming from so, if you unplug it and spray cleaner on the plug & sensor to clean it you can then recheck for the presence of new oil leaking through the sensor (a sure sign it's failing)

The nice thing about diagnosing an ICP problem is that when unplugged, the PCM will default to a limp setting and allow the truck to run without it. If that improves your symptoms you have a good idea as to it's condition.

BUT all-in-all they're an expensive thing to just "buy and see" so, a good scanner will eliminate any questions.
