ICP Sensor

Does anyone know where the ICP sensor is located on a 2000 7.3 and how hard is it to replace?

I'm n ot sure about the 7.3 but i know someone who would know...let me see if i can get him in here.

Its to the right of the fuel filter bowl on side of 'valley'. It has a 3 wire plug. Looks like a coolant temp sender - very easy to replace.

What's going on? It is also in a place where it is EASILY affected by washing under hood. If plug gets wet, it will cause very weird things to happen - including no-start.

[Clay]

yes, why do you think it needs replaced?

I took my truck into the dealership because of a diesel fuel leak. Its to cold here for me to do my wrenching myself. I am a shade tree mechanic and it is mighty cold here in the shade these days.

They found the diesel fule leak in one of the fuel lines. Price $265. The also said the ICP is leaking oil and it is getting on the plug and could cause problems in the future. Price $517. And I also have a leak at the intercooler tubes so to put new boots on is another $314. I told them to fix the fuel line and I will take care of the rest.

Thanks for the information! How much do you think the ICP will cost?

This quoted from a Ford Master Diesel Tech on PS.org....
When i asked him about your question and what the dealer told you he said


ill tell you what i think, sounds like they are slow and are trying to upsell work, if i were him, id fix the fuel leak, and drive the truck, the icp can seep for a long time ad never give trouble , may not even be anything wrong with it , and the cac boots always seep , no need to replace those

Clay I think he called it... my truck was the only diesel in the shop. Thanks for checking on PS.org for me. I am back on the road with no diesel leak and $315 lighter in the hip pocket.

Dude, that is just wrong. I hate dealers, I guess starving dealers are even worse.

The 'diesel leak' was prolly a vibra-loc sleeve - cost $5/ea at dealer or $0.25 anywhere else. I've never heard of a line failure before...

"ICP leaking oil on plug..." WTF is he talking about!! The ICP sensor threads into the high pressure oil (HPO) galley and reports pressure to CPU (brain) which tells HPO regulator how much press. to make. If its 'leaking', then you'd have oil dripping off the back of engine after the valley between heads filled up. IF it actually is leaking, I'd pull it and apply fresh coat of thread sealant and see what happens.

The intercooler boots ALL leak some oil, every last one. The factory boots suck and make it worse. I highly recommend dieselsite.com boots, they are 1000% better than OE and likely will last forever (oil breaks down OE boots, I guess thats part of the 'built in obsolescence' program ) I even got a few more psi of boost after changin' the boots!! Many have chosen to remove the crankcase vent from intake air and vent to atmosphere using a long peice of hose. This removes the oil from IC, etc and makes for a MUCH cleaner engine compartment. I haven't decided its enough of a 'problem' to do this to my junk yet.

Everyone should bookmark www.powerstrokeshop.com for anything OE you need. They are a dealer that sells parts WAAAAY below retail. ie, I just bought fuel filter drain valve for $32 - stealership here wanted $57. I've also bought an A/C clutch, engine fan clutch, 4wd ball joint kits (MOOG!!), glow plug wiring repair kit, under valve cover harnesses, clutch pedal assbly - and plenty more over the years. They have always shipped same day and I got the package(s) 2-3 days later - 100% accurate too! (can't say that for ANYWHERE else I've purchased from lately...)

Moral to this story? NEVER trust the dealership. If you become edumacated 'bout your truck at all, you will find you know more about it than 90% of stealership 'certified' techs. (off rant )
