Icp sensor
2001 250 7.3
Can’t find the injection control pressure switch on autozone... is it called something else? Also I unplugged it while it was idling and it still ran doesn’t that mean it’s bad? Has oil in it and it died violently on the road today with rough idle. But it runs ok sometimes... help???

1.) You should try to avoid plugging/unplugging sensors while it is running. It can ( although very unlikely) damage the ECM
2.) The engine WILL run with the ICP sensor unplugged, regardless of it being good or bad. Once its unplugged, the condition of the sensor is no longer a factor. When the ICP sensor is unplugged, the ECM uses default values and "pretends" like there is a sensor there.
3.) Yes, oil in the plug means the internal seal has failed, and you need to replace the sensor. Depending on how long it has been soaked in oil, as well as its general age and condition, its probably a good idea to also replace the wire pigtail and plug at the same time.
4.) Autozone does sell an aftermarket ICP sensor. I'm not going to help you find it. When it comes to sensor, and a number of other parts, these engines/computer systems just flat out don't like or work well with aftermarket parts. The aftermarket parts are often poor imitations that apparently often don't adhere to the proper tolerances and/or design specs and just don't function well in our engines. If you get lucky and it does work at first, they will not last long.
Use OEM Ford Motorcraft only ( or the International/Navistar equivalent in some cases).
First get the proper Ford Part# for the ICP, then use that to do some shopping. You can find one on Amazon or Ebay, usually for a lot less then at the dealer. Just be careful you are getting a genuine Ford/Motorcraft part.
