P06DD: Engine Oil Pressure Control Circuit Stuck Off

Most Reported On
P06DD is an OBD-II diagnostic trouble code meaning “Engine Oil Pressure Control Circuit Stuck Off.” This code applies to engines with an electronically controlled, variable oil pump, where a solenoid (oil control valve) switches the system between low- and high-pressure modes based on engine needs. 'Stuck Off' means the computer commanded the solenoid but the system did not respond, so oil pressure stays in one mode and cannot be properly regulated. This is frequently triggered by low or dirty oil, or by a stuck or sludged-up oil control valve. Symptoms can include engine noise, rough idle, reduced performance, and warning lights — and it should be addressed promptly to protect the engine. This code is most commonly reported on 2014-2019 Chevrolet Silverado 1500, 2007-2020 GMC Yukon, and 2014-2023 GMC Sierra 1500, plus 9 other vehicles, with repair costs ranging from $100 to $18,000.
