How do you fix trouble code P2290 on a 2005 Ford F-250 Super Duty 6.0 diesel?

Answer 1

P2290 indicate a difference in the commanded and actual injection control pressure.

• Possible causes:

• incorrect oil or viscosity
• poor oil quality
• gelled fuel/no fuel
• low fuel pressure
• biased ICP sensor
• IPR valve
• high-pressure oil system leak
• high-pressure oil pump
• PCM

• Verify correct oil quality/viscosity and correct fuel grade are being used for the temperature conditions

MOST LIKELY HIGH PRESSURE OIL LEAK (DUMMY PLUGS IN HIGH PRESSURE OIL RAIL)

OR..... STC FITTING ON BACK OF THE HPOP. MAY HAVE BLOWN OFF DO THE DUMMY PLUGS TOO WHILE YOUR AT IT YOUR GONNA HAVE TO DO IT ONE DAY IF YOU DO IT NOW YOUR BRANCH TUBE WON'T BE BENT IF YOU WAIT AND IT HAPPENS YOU MIGHT NEED A BRANCH TUBE DEPENDING ON HOW HARD IT BLOWS OFF AND A REAR COVER TOO CAUSE WHEN THEY REALLY BLOW OFF IT CAN CRACK THE REAR COVER AND NOW YOUR TALKING BIG $$. BUT YES LOW ICP IS TYPICALLY DUMMY PLUGS, STC FITTING IF THEY HAVEN'T EVER BEEN DONE. IPR CAN CAUSE TOO AFTER SOME MILES ARE PUT ON IT SO DON'T FROGET THE IPR TOO OH YA AND THE HPOP DO FAIL NOT THAT COMMON BUT SOMETIMES THEY DO. JUST DO THE RAIL PLUGGS AND STC AND BE DONE WITH IT! GOOD LUCK
