P2290 on Ford
Injector Control Pressure Too Low
P2290 on Ford vehicles indicates injector control pressure too low. Au7o has documented this code across 1 Ford model — most commonly on F-250 Super Duty. Found on direct-injection diesel engines, this code means the actual injector control pressure is lower than the PCM commanded. Insufficient high-pressure oil/fuel to actuate the injectors leads to poor or no injection. Typical repair costs on Ford range from $600 to $1,600, depending on the specific model and root cause.
Common Causes of P2290
- •Low engine oil level or pressure
- •Leaking high-pressure oil system or injector o-rings
- •Failed injection pressure regulator (IPR) valve
- •Weak high-pressure oil pump
- •Failed ICP sensor / wiring
P2290 on Ford by Model
Ford F-250 Super Duty(1 issue)
- 6.0L Power Stroke STC Fitting Failure on the High-Pressure Oil Pump - Hot No-Start2005-2007
For the 2005 model year Ford revised the 6.0L's high-pressure oil pump and introduced a two-piece 'snap-to-connect' (STC) fitting on the HPOP branch tube. The two-piece fitting flexes with engine movement, wearing the internal seal and the locking ring until high-pressure oil leaks past it - or until the fitting separates outright. Because the HEUI injectors need roughly 500 psi of oil rail pressure to fire, the truck develops the classic pattern owners describe on the forums: it starts fine cold, then hot restarts get progressively longer, then one day it will not start at all after a fuel stop. It is one of the most common no-start causes on 2005-2007 trucks and is frequently misdiagnosed as injectors, a bad HPOP, or standpipes/dummy plugs (which fail with the same symptom set).
