The P0551 code on your 2019 Nissan Rogue indicates the power steering pressure sensor is providing readings outside the expected range. The sensor works but its values don't make sense to the ECM.
Range/Performance Issues
P0551 is a rationality code—the sensor is connected and providing data, but the readings are implausible. The ECM compares pressure readings to expected values based on steering effort, engine load, and other factors.
Rogue Steering Configuration
The 2019 Nissan Rogue uses electric power steering (EPS), which doesn't have a traditional hydraulic pressure sensor. If you're seeing P0551, verify the code interpretation—some scan tools may misread or this could relate to a different pressure sensor.
Understanding the Code on EPS Vehicles
On vehicles with electric power steering, P0551 may not apply in the traditional sense. The code could be a database error or relate to another pressure sensor. Use Nissan Consult for accurate code interpretation specific to your Rogue.
Diagnostic Approach
Verify your Rogue's steering type—most are EPS. Use Nissan Consult to read the actual fault code and description. If the vehicle does have a pressure sensor, monitor readings during steering operation. Check for related codes that might clarify the issue.
