P06DA on Ford by model: symptoms, diagnosis and fix
The 2.0L EcoBoost engine in the 2015-2024 Edge uses an internally mounted water pump driven by the timing chain. When this pump fails, it leaks coolant internally into the engine oil, contaminating the lubrication system and potentially causing severe engine damage. Unlike a traditional water pump that leaks externally and gives visual warning, this internal failure can go undetected until oil analysis or engine damage reveals it. The pump is buried inside the engine behind the timing cover.
Common Symptoms
- Milky or frothy engine oil on dipstick
- Coolant level dropping without external leak
- Engine overheating
- Oil pressure warning light
- Sweet smell from oil filler cap
- White residue on oil cap
How to Fix
Replace the water pump. Due to the internal location, this is a major repair requiring timing cover removal — labor is 8-12 hours. Parts cost $150-300 for the pump plus timing chain components. Total repair: $1,500-3,000 at an independent shop. If coolant has mixed with oil, the engine may need additional flushing or repair. Monitor oil color — milky oil indicates coolant contamination. Change oil more frequently and check coolant level regularly.

Frequently asked questions
What does P06DA mean on a Ford?
P06DA stands for "Engine Oil Pressure Control Circuit/Open." This code indicates the engine computer detected an open circuit (or other fault) in the engine oil pressure control circuit, typically the wiring or solenoid that regulates a variable-displacement oil pump. The PCM monitors this circuit to maintain proper oil pressure for lubrication and variable valve timing. Because loss of oil pressure can quickly cause severe engine damage, this should be treated as urgent. On Ford it is documented across 1 model: Edge.
What are the most common causes of P06DA?
The most common causes of P06DA are: Faulty oil pump control solenoid/valve, Open or shorted wiring in the control circuit, Corroded or loose solenoid connector, Low oil level or low oil pressure, Faulty oil pressure sensor, PCM control circuit fault. The specific cause varies by vehicle.
How much does it cost to fix P06DA on a Ford?
Published repair estimates on Ford range from $1,500 to $3,000 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.
