I bought a 2000 F250 Super Duty 7.3 Powerstroke, 4x4 with automatic transmission. Was told the engine was replaced with a 2002 crate motor. I am trying to determine if my PCM matches the motor. Engine number: T444 LF 250847 followed by 112 0303
Can't find any information online about the engine. The PCM is number: F5SB-14A624-AA struck out on this one too.

 

Can I ask why you're trying to figure out if they match each other?

 

I was told that the 2000 PCM is different from the 2002 and that could be the reason I am getting some codes that repeat even though I have replaced the faulty components.
Never thought finding someone with the ability to decipher the engine serial number would be so difficult.

 

Did I post this in the wrong forum? Maybe one of the moderators can shift it to the 1999-2003 category?

 

can do.
and welcome to FTE.
i am going to move this to the electrical system/wiring forum, i think you may get more help there. if not you can then repost in the 99-03 powerstroke forum.

 

I am looking at crate engines like these people sell

POWERSTROKE CRATE ENGINE

I see no sensors or wiring on them at all. So I am thinking when it's swapped in, all the top engine dress from the old engine goes on the new, and should be compatible with the old PCM.

 

No worries, I'll move this over to the 7.3L forum.

You don't need that to try and diagnose what's going on with your engine. The guys here will get you squared away once they start asking you what's what on your truck, and what you've done to try and make it right.

Unfortunately I don't know for sure if it was a basic crate engine or not. A sticker on the passenger's valve cover says Remanufactured but doesn't give any other information.
I see some replacement engines do have the sensors:

Please list the codes you're setting so we can help diagnose your problem.

Go to a Ford dealer, have the parts guy type your 2000 F250's VIN into the system, then you'll know what the original Ford part number was.

If you don't have the VIN from the vehicle that the swapped engine came from, the parts guy can look thru the applications or Calibration Code charts to find the part number.

Then you'll know if it's the same as yours....or not.

The only thing I can tell you is: F5SB is the ID engineering number prefix for a 1995 Thunderbird, but this doesn't necessarily means that it's incorrect.

One thing parts guys learned when Ford began installing computers in the early 1980's. If the engine was swapped, the original computer usually didn't match the swapped engine.

So whatever vehicle the engine came from, you also needed the computer from it. Use the original computer, the engine could run rough or it might not run at all!

 

If it is in fact a 2002 engine, then a 2000 PCM will run it no problem. There are no different sensors or data that the 2000 PCM would expect from a 2002.

 

Yes, the PCM is different. Primarily in the communications protocol and charging system but nothing in the way the engine is controlled. Repeat codes after replacing components that are "faulty" means that the parts weren't faulty.

 

Okay, the codes I keep getting are P0670 = Glow Plug Module Control and P1690 = Wastegate Control Valve Malfunction.

Put a new Glow Plug Control Module (California style, not solenoid) in. While doing so I checked the continuity of the glow plug circuit to each plug.

I then purchased a new Wastegate solenoid and hose kit. Before installing I applied 15psi to the actuator and it opened and then closed when I relieved the pressure.

Cleared the codes by disconnecting the battery and operating the horn circuit for 30 seconds.

Truck seems to run fine but the codes come back.

Oh, and I took out the PCM again and found some numbers carved into the plastic connector. 8677F which a online search came up with a DPC-452 PCM.

 

You have the WRONG PCM in the pickup.

2000 MY pickups didn't come with DPC-452 PCMs....even the 50-state emissions ones didn't have glow plug modules (they used a relay and a DPC-432 PCM).

Disconnecting the batteries and running electrical stuff will not clear trouble codes either.
