P0846 Nissan Description The Transmission Control Module (TCM) has detected a fault in the pressure switch assembly Nissan Vehicle: Nissan 370Z,Nissan Altima,Nissan Armada,Nissan Frontier,Nissan GT-R,Nissan Juke,Nissan Maxima,Nissan Murano,Nissan Pathfinder,Nissan Quest,Nissan Rogue,Nissan Sentra,Nissan Titan,Nissan Versa,Nissan Xterra. P0846 is a diagnostic trouble code (DTC) for 'Transmission Fluid Pressure Sensor/Switch 'B' Circuit Range/Performance'. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Error Code P0846 is a generic trouble code, meaning it applies to all vehicles with the OBD-II system, especially those made from 1996 up to present. This includes vehicles from, but not limited to, Chrysler, Chevrolet, Dodge, GMC, Honda, Nissan, and Toyota. However, it seems to be more common among Nissan.
