OBD-II trouble code
P06DA: Engine Oil Pressure Control Circuit/Open
Application matters: P06DA concerns the engine oil-pressure control circuit, not a direct reading of current oil pressure. Identify the installed output and full failure designation using the exact engine information. An oil-pressure warning, abnormal engine noise or oil loss needs immediate assessment before any running test.
The oil-pressure control circuit reported a circuit/open fault. The code does not identify a failed valve or establish whether engine oil pressure is adequate.

A code alone cannot establish whether driving is safe. Stop safely for a red brake or oil-pressure warning, overheating, severe misfire, stalling, or impaired braking or steering, and follow the owner's manual. Restraints faults can reduce crash protection even when the vehicle runs normally.

What does P06DA mean?
P06DA is a circuit/open designation for the output that controls engine oil pressure. It concerns the monitored electrical control path. It is different from an oil-pressure sensor input code or a report that actual oil pressure is too low. A general circuit/open result does not, by itself, locate a broken wire or condemn a control valve.
In Ford’s covered 2024–2025 gasoline example, P06DA/P06DA_13 belongs to the oil-pressure control solenoid circuit check. The listed result is an output-circuit fault reported by the smart driver. Ford describes functional checks separately, so an electrical repair still needs the confirmation required for that engine. Neither a circuit result nor the absence of another code establishes that pressure and control response are healthy.
Give the repairer the complete code, current status, event information and any oil-pressure warnings or recent service history. A connector, control component, wiring path or driver problem must be distinguished using the actual schematic and protected tests. Recent oil or filter work is useful history, not proof that the service caused this electrical code.
Pressure verification belongs to the engine-specific professional procedure. A mechanical gauge may be required by that procedure, but it is not a universal first step for every circuit fault. Do not keep the engine running to obtain readings when an oil-pressure warning, new mechanical noise or visible oil loss calls for shutdown and assistance.
Possible causes
- Damaged wiring or terminal contact in the identified control-output circuit
- An electrical fault in the control solenoid or its connections
- A supply or return problem established for the installed circuit
- A controller output-driver fault confirmed by the applicable tests
Symptoms
- Check-engine warning with P06DA recorded
- Companion oil-pressure or control-system faults
- An oil-pressure warning or abnormal engine noise requiring prompt shutdown assessment
- Few noticeable symptoms despite the stored circuit fault
Diagnostic steps
Save the full scan report, code status, and available freeze-frame data before clearing anything. Confirm the reporting module, any failure-type suffix, and the procedure for the exact vehicle. The steps below are an overview; use manufacturer specifications and safety procedures for testing.
- 1.Follow the handbook for an oil-pressure warning, new engine noise or oil loss. Stop safely, shut down as directed and arrange assistance; do not restart merely to reproduce the code.
- 2.Preserve the full DTC, status, event data and companion codes. Record recent oil/filter work and warning behavior without assigning a cause from timing alone.
- 3.Identify the actual control output, wiring and failure-type designation for the engine. Do not confuse the control solenoid with the pressure-sensor input.
- 4.With the engine stopped and ignition off, note safely accessible visible damage for the repairer. Avoid hot components and unfamiliar connectors.
- 5.Have a qualified technician perform the prescribed protected circuit and component checks. Do not bridge terminals or apply battery power to a valve as a generic test.
- 6.Complete the indicated repair and the engine-specific circuit/function confirmation. Perform pressure verification in the manner and sequence the actual procedure requires.

A trouble code alone does not price the repair. Ask the shop to identify the confirmed fault and itemize diagnosis, parts, labor, programming or calibration, and taxes.

DIY vs shop
A qualified shop is recommended because this can involve manufacturer-grade tooling, training, or certification that most home setups do not have. Ask the technician what testing confirmed the repair.
