Hello, I am new to diesel engines and want to learn as much as possible. I have an issue somewhere that I may have made worse.
I have a 2006 f-250 6.0 powerstroke turbo diesel, 210k miles, a few days ago the engine started sputtering real bad and the rpms wouldn't go above 2200 without easing into it, had lost a lot of power, it shut off at a red light and then wounded fire right back up, after a few cranks it did and the check engine light came on. The code was for the icp sensor. Today I unplugged the sensor to see if it would start and it fired right up and ran fine.
. This is where I think I messed up, I left it unplugged, cleared the code, started it up and increased the rpms, it killed the engine and wont start back up with the sensor plugged in or not. I have not sat and cranked it much because I don't want to cause any further damage. I figured maybe once it cools down it may start, should I try with the sensor plugged in or unplugged. Or should I leave it until I replace the sensor which will be tomorrow.
Any help and guidance would be greatly appreciated.

 

I'm not super informed on the 6.0, but on a 7.3 when you unplug the ICP the computer defaults to assuming it has about 600 psi.
It could be that revving it up depleted the oil in your oil rails/reservoir and it died because of that.
I don't think you could have damaged anything, you'll just have to crank on it a while to replenish the oil in the high pressure system. I wouldn't mess with it any further until you get hte new sensor in.
And remember, your just throwing parts guessing what might be happening. It is about the easiest step, but might be a waste of time.
Only use Ford/Motorcraft sensors, all the aftermarket ones are garbage.

When you have the icp sensor out, connect a hose to the port, direct it into something to catch oil, and crank the engine.
Look up the starter wire on the passenger fender and how to use it to crank the engine without presurizing the fuel system and starting the truck, it will be alot easier that way.
When you crank it, make sure to give your starter a break. 10 seconds cranking, 2 minute cooldown, 10 seconds cranking, 2 minute cooldown, 10 seconds cranking, 15 minute cooldown.
I'd put a battery charger on it also.

 

Oh yeah, Welcome to FTE!

 

OK, thank you very much, i am actually looking for the battery charger now, i tried to crank it a few times but not long.so ill grab the sensor, replace it then make an attempt to start it. Thank you very much, i appreciate it.

 

thank you, I'm sure I'll be around for a while, I may have a 01 f350 with a 7.3 that I'm going 5o be fixing up while I learn diesel engines lol. I know the upper pipes are cracked, has a miss and driver side valve cover is leaking.

 

The 7.3 forum is great here also, make sure to check in over there.

 

Welcome, JB. The best investment you'll make for this truck is to buy an OBDII wireless connector. They're <$50 online. You either get a Bluetooth version (Android phones and Windows PCs/tablets) or a WiFi version for Apple phones and PCs/tablets. With that, you can buy the Forscan app for $6 downloaded to your phone and it'll let you monitor all the data and read all the codes and perfom several diagnostic tests. There are more expensive solutions - the Ford IDS software is best - but Forscan does everything you typically need.

Without that, with nothing but your description of symptoms that could be caused by any of several issues, it's hard for anyone to help you. It's expensive throwing parts at problems, although, you could end up with some known-good spares for next time. Speaking of spares, I'm the lone advocate here for knowing where your local pick-u-part yards are. If you're near any major city, there's prolly several, including LKQ. You can set up alerts to be notified when trucks come in. Pick up a lot of spare parts for testing purposes real cheap. Sensors and pigtails especially.

I've never had an ICP sensor fail, but have read that one sign is oil seepage around it on the valve cover.

 

thank you very much, I will look into that. I noticed that I need to be able to read pressures and everything while reading on here. I am located in Cincinnati Ohio, that would be helpful.
