The P0747 code in your 2019 Nissan Rogue indicates that the pressure control solenoid is stuck in the on (high pressure) position. Your Rogue uses a CVT that requires precise pressure control for belt clamping and ratio changes. When the solenoid is stuck on, pressure remains high regardless of driving conditions.
High Pressure Implications in CVT
A stuck-on pressure control solenoid forces the CVT to operate at high pressure constantly. While this prevents belt slippage, it causes harsh operation, excessive wear on the belt and pulleys, reduced fuel economy, and potentially delayed or harsh ratio changes.
Common Causes
The solenoid may be mechanically stuck due to debris or internal failure. Valve body issues trapping the solenoid in the high-pressure position. Wiring problems keeping the solenoid energized. Internal contamination in the CVT affecting hydraulic circuits. Electrical failures in the solenoid coil causing constant activation.
Symptoms in Your Rogue
Harsh or jerky CVT operation throughout driving. The transmission feels aggressive or abrupt. Higher RPM during acceleration than expected. Reduced fuel economy due to constant high-pressure operation. Possible whining noise from the CVT. Check engine light with P0747 stored.
Nissan CVT Diagnosis
Using Nissan CONSULT, monitor line pressure during various driving conditions. Pressure should vary with throttle and load—if it stays constantly high, the solenoid is stuck. Check solenoid electrical operation. Inspect CVT fluid level and condition. Note that Nissan CVTs are sensitive to fluid condition and level.
