just bought one not long ago and not filmier with all the abbreviations but I have been told either cam position sensor or crank trigger sensor. hope this helps

 

IPR= Injector Pressure Regulator.
ICP=Injector Control Pressure.
IDM= Injector Driver Module.
CMP= Camshaft position Sensor..[that's the recall issue]
EBP= Exhaust Back Pressure


KOEO= Key On Engine Off
KOER= Key On Engine Running

 

Is it low on oil ?

 

No....I wish it would be that easy...LOL

 

The right oil is critical, must be CI4 rated without that it will cause misses. I had 3 injrctors go bad at 275,000 miles, it needed both harnesses at that time also.

 

again sounds like crank trigger or did you replace that too! just a thought.

 

Yes, I already did, covered under Ford 07S57 recall

 

check and make sure it has 60psi of fuel pressure and good clean fuel...if pressure is low on output side of pump , check on inlet side of pump..if it starts to pull vac, then suspect filters in sending unit are plugged...filters inside of sender resemble 2 roll of dimes......make sure oil is clean and full....write down dtc's ...clear dtc's then re start/re check

 

Yes, oil is clean and full.....fuel pressure is good.....no DTCs after replacing cyl 7 injectors but when performing KOER cylinder contribution test, cyl 1,3 & 5 failed [ very unusual on 7.3 diesel]....

if it was low on fuel pressure then it won't be smoking like mosquito fogger....smells like fuel in incomplete combustion [only when engine is hot].....

already did coolant system pressure test and vacuum test and combustion gas in coolant test...all are pass....

enough headaches for a day...till tomorrow....

 

I AM A CERTIFIED FORD DIESEL MECHANIC IT ONLY CAN BE THREE THINGS CRACKED HEAD, BAD INJECTOR CUPS WHICH IF ITS A BAD CUP YOU SHOULD HAVE DIESEL IN THE COOLANT IF IT NOT ITHER ONE OF THOSE ISSUE I CAN ASSURE YOU THAT THE TURBO IS BAD YOU NEED TO MAKE SURE YOUR WASTE GATE IS OPENING CORRECTLY AND MAKE SURE YOUR TURBO SHAFT DOESNT HAVE EXCESS SLACK OR YOU MIGHT HAVE SOME BAD INJECTORS THAT THE ONLY THING THAT WILL MAKE IT DO SOMETHING LIKE THAT

 

and yes, low fuel pressure due to clogged filters in pickup can cause smoke ,running rough also......i also am a senior master tech.........very good info listed on here for checking.....good luck

 

did not have the chance to work on it today....had to finish torqshift trans overhauled.

 

had a 7.3 smoking and giving contribution codes......compression test showed base engine was nfg.

 

Any word?

 

sorry for delay..got awfully busy and this week I got send to school for Advance Engine Performance training.

anyway, motor is junk, cylinder 1,3,5 compression are 40% low than others...it is first time I've seen three cylinders in a row has low compression.....customer declined repairs and op for reman motor.
