P0026 Subaru - Intake Valve Control Solenoid Circuit Range/Performance Bank 1
- Low engine oil level
- Faulty intake valve control solenoid
- Intake valve control solenoid harness is open or shorted
- Intake valve control solenoid circuit poor electrical connection
The Continuously Variable Valve Timing (CVVT) system is installed to the chain sprocket of the intake camshaft. This system controls the intake camshaft to provide the optimal valve timing. The Engine Control Module (ECM) controls the Oil Control Valve(OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature. The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease under overall driving conditions.
Any information is appreciated. Thanks
