P06DD GMC Code - Engine Oil Pressure Control Solenoid Valve Performance
Quick Answer
The Engine Oil Pressure Control Solenoid Valve is used to control engine oil pressure inside the mechanical engine oil pump. Common causes include Faulty Engine Oil Pressure Control Solenoid Valve, Engine Oil Pressure Control Solenoid Valve harness is open or shorted, Engine Oil Pressure Control Solenoid Valve circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P06DD GMC Description
The Diagnostic Trouble Code (DTC) will be set when the Engine Oil Pressure is less than a predefined threshold.
What are the Possible Causes of the DTC P06DD GMC?
- Faulty Engine Oil Pressure Control Solenoid Valve
- Engine Oil Pressure Control Solenoid Valve harness is open or shorted
- Engine Oil Pressure Control Solenoid Valve circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P06DD GMC?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
If an oil change was recently performed, clear the DTC using GDS and verify the code does not return.
The DTC P06DD setting is likely due to the oil filter not being pre-primed with engine oil before installation, causing low or no oil pressure on the initial start-up.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P06DD GMC code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P06DD GMC Code
1. What does the OBDII code P06DD mean on a GMC vehicle?
The P06DD code indicates an issue with the Engine Oil Pressure Control Solenoid Valve, which is not performing as expected, potentially affecting oil pressure regulation.
2. What are the common symptoms of the P06DD code on a GMC?
Symptoms include the check engine light being illuminated, low oil pressure readings, engine ticking noises, and potential engine performance issues.
3. What causes the P06DD code to appear on a GMC?
Common causes include a faulty oil pressure control solenoid valve, low or dirty engine oil, a clogged oil filter, wiring or connector issues, or a malfunctioning oil pump.
4. Can low oil level trigger the P06DD code on a GMC?
Yes, insufficient engine oil can cause the P06DD code, as it may impair the oil pressure control solenoid's ability to regulate pressure correctly.
5. How serious is the P06DD code on a GMC vehicle?
It can be serious, as improper oil pressure regulation may lead to inadequate engine lubrication, increasing the risk of engine damage if not addressed promptly.
6. How can I fix the P06DD code on my GMC?
Start by checking the engine oil level and quality, replacing the oil and filter if necessary. Inspect the oil pressure control solenoid valve and associated wiring, and replace faulty components as needed.
7. Can a dirty oil filter cause the P06DD code on a GMC?
Yes, a clogged or dirty oil filter can restrict oil flow and impact the pressure control system, potentially triggering the code.
8. How do I test the oil pressure control solenoid valve on a GMC?
You can test the solenoid valve using a multimeter to check for proper resistance and inspect for physical damage or oil contamination on the valve itself.
9. Is it safe to drive with the P06DD code active on a GMC?
It's not recommended to drive with this code active, as it may lead to engine damage due to improper oil pressure or insufficient lubrication.
10. How much does it cost to repair the P06DD code on a GMC?
Repair costs can vary but typically range from $150 to $400, depending on whether the issue is a simple oil change, solenoid valve replacement, or more complex repairs.
