Noob Acronym help.

Just purchased an '06 F-350 Lariat to haul and pull a dump trailer for the business and property.

I have been learning as much as possible on here but have a couple of questions I have yet not been able to understand.

What is STC, and where is this fitting I will have to upgrade to the new one?

What is ICP, and again what do I need to know about it.

CCV?

IPR?

One more, is there a way to tell what rear-end gear I have easily?

This is our first diesel. We were beating the snot out of our Suburban trying to pull with it and decided it was time to get a real work truck.

STC is a fitting that connects your HPOP (high pressure oil pump) to the high pressure oil system. Famous for exploding and leaving you stranded on the side of the road.

ICP: Injection control pressure (sensor). This monitors the high pressure oil pressure present within the oil rails sitting on top of your injectors.

CCV: CrankCase Vent. This creates an oily mess in your air intake tubes. It vents the oily smoke out of your crankcase and routes it to the black plastic piece just behind your air cleaner and just before your turbo. This makes the turbo suck the oily mist in, and push the oil through the rest of the intake system.

IPR" Injection Pressure Regulator. This is screwed into the side of the HPOP. To explain it so it all makes sense..
Oil drops below theoil cooler and makes its way into a small reservoir under it. This oil then enters a channel machined into the block and flows to the HPOP. The HPOP just sucks this oil up and pressurizes it. The IPR is used to regulate what pressure the HPOP introduces into the high pressure oil system. The oil leaves your HPOP through the STC fitting, then enters the branch tubes. Look at the branch tubes much like a Y pipe. It splits the oil flow into two. The oil flows out of the branch tubes and enter standpipes. The standpipes deliver the oil up to the oil rails. The ICP sensor tells your PCM (powertrain control module) what pressure it is "seeing" and the PCM uses the IPR to regulate the oil pressure to set values in the progarmming.
The high pressure oil rails are common to both sides of the engine. That requires that the hole used on one side for the standpipes, would have to be blocked on the opposite side. The plugs for those holes are known as "dummy plugs"

The high pressure oil is used by your injectors to regulate the fuel flow. If you look at the injector like a doctors needle, the pressure the doctor places on the plunger to inject you is the high pressure oil systems purpose. The actual injector timing is accomplished electrically, and your FICM controls the electrical portion of your injectors. (Fuel Injection Control Module)

The easiest way to tell what gear ratio you have is to slide under the rear of your truck and read the metal tags on the diff cover.
3L73 would mean 3.73 gears, the L designates the differential as the "limited slip."
No "L" and you have an "open" style differential.

HPOP is High Pressure Oil Pump
ICP is the Injector Controll Pressure Sensor
IPR is the Injector Pressure Regulator (high pressure oil regulator)
FICM is Fuel injector controll module (6.0)
IDM is Injector driver module (7.3)
PCM is Powertrain controll module
LOF is Lube, Oil, Filter
CMP or CPS (cmp is the dealer term, cps is the forum term for some reason) is Camshaft position sensor
UVCH is under valve cover harness (7.3)
Y pipe is the pipe at the back of the motor, that comes off the exhaust manifolds to feed the turbo
MAP sensor is manifold absolute pressure sensor, how the PCM knows boost levels. It is Boost+atmospheric pressure
MGP is manifold gauge pressure, or true boost (MAP-atmospheric pressure)
EOT sensor is Engine oil temp sensor
EGT is Exhaust gas temp (never a factory sensor)
ECT sensor is Engine coolant temp sensor
H2o pump is water pump
P/S is powersteering
IAT is Intake air temp sensor
IAH is intake air heater
CAC is Charge air cooler. A CAC tube is either tube that runs from the intercooler to the motor
Rad is Radiator
CCV is crancase ventalation
Degas bottle is the coolant bottle on a 7.3 or 6.0 where the radiator cap is on the bottle and not the radiator
APP is acelerater pedal position
ABS is antilock brake system
SRS is suplimental restraint system (air bags)
OD or O/D is overdrive
EGR is exhaust gas recirculation (6.0 and 6.4 only). It consists of a valve, and cooler(s)
WOT is Wide open throttle, or pedal to the metal:burnout

Rob, nice list. I wish I had one of these at work!

[NYC F-350]

Want more info? For a true understanding of the engine, its design and the component names and locations, download the following links for books about each year.
2003.25 model year. This is the first creation. Many changes to come...
2004 model year. This book is mostly just the changes made to the engine for this year.
2005 model year. The last book on the 6.0 This would resemble what version engine you have.

Once you have done all of that, click HERE and read up some more.

The first link in my signature (basic info) will tell you many things that a 'newb" should know about this engine. Please, do yourself a favor and take 10 minutes to read the thread.

Welcome to the ORG.

LOL thanks, I cannot take credit for it though, it was posted before by one of the old Admins that is no longer here.
