Dreaded P0216 code, help/advice

Posted
  • Staff

 So on my way to work this morning I noticed my pedal was for the most part dead. No acceleration and the engine was "missing" for lack of a better term.

 Made it to work, truck idled smooth like any other day but if revved a few times it would begin to miss again.

 Had the OBD scanner in the truck so plugged in and saw the P0216 code. That was the only code present.

 I know this is the VP death code but before I drop big $$$ on a pump, is there anything else I need to look at? I want to properly diagnose this and not just throw money at it. Can't afford that rout right now.

 Thanks in advance......

    As long as your pressure is reasonable it can't hurt anything and I'd certainly try it.  As goopy as the stuff was around my screen (imagine wet coffee grounds, but much finer), it may not "clear it"

    Since the word “cavitation” has been used a few times in this thread, I thought I would clarify the meaning of “cavitation”, specifically “pump cavitation”.   When the suction pressure of a

That would be nice if someone had published flow at specific  pressure ratings.   It may have already been done, but I am not sure where it has been posted.

 

From Bosch

TYPE FORMULA on the pump for the 0470506028 is  VR6/3/70M1600R1000

0470506027 VR6/3/75M1600R1000

 

This is my understanding: ( someone please add to it.)

VR6 = 6 fuel lines

3 = plungers

70m = reference for the size of the plunger

1600R = I think is the RPM for testing (2x pump stand ) 

1000??

 

The Scheid Lightning II pump is supposed to supply 100cc more fuel than stock

@dieselautopower, thank you very much for this information.  This is good information for deciphering the code for the business end of the VP44, but what I really want to know is the displacement of the internal vane pump in terms of cubic inch per revolution.  If you happen to find a source for this information, please let me know.

 

I appreciate your quick response.

 

Thank you,

 Installed the Raptor 150 today. Instalation went well despite my big hands in small places. Pump is on along with the 1/2" line from pump to filter housing. I was unable to install the larger line from filter to vp44 because to do so I would have lost the pressure test fitting at the vp44. I needed this to check/set pressure of the new pump. I will be ordering a fuel pressure gauge to mount in cab soon. Then the 1/2" line will go on to the vp44.

 So far all is well, pressure is rock solid at 18psi. No codes in the OBD2. 

 I also did the lift pump relay to lighten the electrical load from the ecm. Now power to the pump is supplied directly from the battery via 15a fuse and then the relay. Triggered by the original ecm power wire for the pump as explained in the article by @IBMobile.

 Soooo glad to have her up and running again!
