Code P06DA 2018 GMC Sierra Description

The Engine Oil Pressure Control Solenoid Valve is used to control engine oil pressure inside the mechanical engine oil pump. The control module controls the commanded state of the solenoid valve based on the following inputs: Engine Speed, Calculated Engine Oil Temperature, Engine Oil Pressure, and Engine Run Time. When the solenoid valve is commanded Off, oil pressure is higher. When the solenoid valve is commanded On, oil pressure is lower.
The Diagnostic Trouble Code (DTC) will be set when the control circuit's commanded state does not match the actual state for greater than 1 s.
