3 vehicles · 2 makes · $50-$4,000 repair
Most Reported On
P06DE is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2009-2023 Chevrolet Traverse, 2015-2022 Chevrolet Trax, and 2019-2025 Cadillac XT4, with repair costs ranging from $50 to $4,000.
