P06DD on Lincoln by model: symptoms, diagnosis and fix
2016-2017 Lincoln MKX models with the 2.7L EcoBoost V6 (engines built roughly April 2016 to January 2017) can suffer excessive oil consumption caused by defective cylinder head valve guides that let oil seep into the combustion chamber and burn off. Owners report burning roughly a quart every 3,000 miles, often accompanied by rough idle, misfires, and blue/white exhaust smoke. Ford addressed this in Technical Service Bulletin 19-2243, whose official remedy is replacement of both left and right cylinder heads. Fouled spark plugs from oil contamination commonly trigger cylinder-specific misfire codes.
Common Symptoms
- excessive oil consumption (1 quart per ~3000 miles)
- rough idle
- engine misfire
- blue or white exhaust smoke
- fouled spark plugs
- low oil warning between changes
How to Fix
Have the dealer confirm coverage under TSB 19-2243; the corrective procedure replaces both cylinder heads (and typically spark plugs). Monitor oil level frequently between services and document consumption to support a warranty/goodwill claim.

Frequently asked questions
What does P06DD mean on a Lincoln?
P06DD stands for "Engine Oil Pressure Control Circuit Stuck Off." 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. On Lincoln it is documented across 1 model: MKX.
What are the most common causes of P06DD?
The most common causes of P06DD are: 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. The specific cause varies by vehicle.
How much does it cost to fix P06DD on a Lincoln?
Published repair estimates on Lincoln range from $4,000 to $8,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
