P06DD on Ford
Engine Oil Pressure Control Circuit Stuck Off
P06DD on Ford vehicles indicates engine oil pressure control circuit stuck off. Au7o has documented this code across 1 Ford model — most commonly on Fiesta. This code applies to engines with an electronically controlled, variable oil pump, where a solenoid (oil control valve) switches the system between low- and high-pressure modes based on engine needs. 'Stuck Off' means the computer commanded the solenoid but the system did not respond, so oil pressure stays in one mode and cannot be properly regulated. This is frequently triggered by low or dirty oil, or by a stuck or sludged-up oil control valve. Symptoms can include engine noise, rough idle, reduced performance, and warning lights — and it should be addressed promptly to protect the engine. Typical repair costs on Ford range from $600 to $8,000, depending on the specific model and root cause.
Common Causes of P06DD
- •Low engine oil level or dirty/sludged oil
- •Faulty or stuck oil pressure control solenoid (oil control valve)
- •Clogged oil passages or solenoid screen from sludge
- •Wiring or connector problems at the solenoid
- •Faulty oil pressure sensor
- •Failing variable-displacement oil pump
- •Incorrect oil viscosity

- Wet Belt (Belt-in-Oil) Timing Belt Degradation Clogging Oil Pump Pickup2013-2019
The 1.0L EcoBoost uses a 'wet' timing belt that runs submerged in engine oil. When oil is old, over-extended, or not to Ford's WSS-M2C948-B spec, the belt's rubber breaks down and delaminates ('pilling'). Shed fragments migrate through the sump and clog the oil pump pickup screen, causing loss of oil pressure and catastrophic engine failure. NHTSA opened an investigation after dozens of complaints of low oil pressure followed by power loss on 1.0L EcoBoost vehicles. Ford originally quoted a very long belt interval (10 yr / 150k mi) but real-world failures pushed independent shops to recommend ~6 yr / 60k mi replacement. Failure can also destroy the belt-driven oil pump and cause the crank pulley to shed the belt.

What does P06DD mean on Ford?▼
P06DD stands for "Engine Oil Pressure Control Circuit Stuck Off."
