P06DE on Chevrolet by model: symptoms, diagnosis and fix
The 3.6L V6 in the Traverse consumes oil at a rate that many owners find unacceptable, particularly on 2009-2017 models with the LLT and LFX engine variants. Owners report consuming 1 quart every 2,000-3,000 miles. The oil consumption is related to piston ring design and the PCV system routing oil vapor back into the intake. The issue is not accompanied by visible external leaks. GM has acknowledged elevated oil consumption on the 3.6L but considers up to 1 quart per 2,000 miles within their acceptable range.
Common Symptoms
- Oil level drops 1 quart every 2,000-3,000 miles
- Low oil pressure warning light
- No visible oil leaks
- Slight blue smoke on hard acceleration
- Fouled spark plugs from oil contamination
How to Fix
Check oil level at every fuel stop and top off as needed. Use the GM-specified dexos1 Gen 3 approved 5W-30 synthetic oil. An oil consumption test at the dealer involves measuring consumption over a set mileage interval — if it exceeds GM limits, warranty coverage may apply. For out-of-warranty vehicles, using a slightly heavier 5W-40 European-spec oil can reduce burn-off. Severe cases may require piston ring replacement ($2,500-$4,000) or valve stem seal replacement ($1,000-$2,000).

The 1.4L turbocharged engine burns oil at an excessive rate, often consuming a quart every 1,000-2,000 miles. The issue is attributed to piston ring design and PCV system routing. GM considers up to 1 quart per 2,000 miles "normal" but many owners find this unacceptable.
Common Symptoms
- Low oil level between changes
- Blue smoke on startup
- Oil smell from exhaust
- Low oil pressure warning
How to Fix
Monitor oil level between changes and top off as needed. Replace the PCV valve and inspect the intake manifold for oil buildup. For severe consumption, an engine teardown to replace piston rings and valve stem seals may be necessary. Use full synthetic 5W-30 oil as specified.

Frequently asked questions
What does P06DE mean on a Chevrolet?
P06DE stands for "Engine Oil Pressure Control Circuit Stuck On." P06DE is a generic OBD-II code indicating the engine computer detected that the engine oil pressure control circuit, typically an oil control solenoid or actuator, is stuck on (energized) and not regulating oil pressure properly. Modern engines vary oil pressure for efficiency and to feed systems like variable valve timing, so a stuck circuit prevents proper control. This can lead to abnormal oil pressure, noisy valvetrain, rough idle, and reduced performance. Because oil pressure problems can quickly cause severe engine damage, this should be treated as urgent. On Chevrolet it is documented across 2 models: Traverse, Trax.
What are the most common causes of P06DE?
The most common causes of P06DE are: Oil control solenoid stuck on or clogged with sludge/debris, Short to power keeping the solenoid energized, Low oil level or contaminated/degraded oil, Damaged wiring or connector in the control circuit, Failed oil pressure control solenoid/actuator, Faulty oil pressure sensor giving bad feedback, PCM/ECM fault (rare). The specific cause varies by vehicle.
How much does it cost to fix P06DE on a Chevrolet?
Published repair estimates on Chevrolet range from $50 to $4,000 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.
