2011 Nissan Maxima - Sensors show trouble - but what?

Engine warning light fault, car runs fine, sensor replaced 3mths of buying 3 mths again now a year and half later again. Sensor replaced three times. PO846 Transmission fluid pressure sensor B Circuit? Nissan micra 2011.

A trouble code just tells you that a sensor is reporting a reading that is out of range. it can be the sensor, a wiring connection, the computer or there can be something causing the fluid pressure inside your transmission to be too high or low. A Nissan Micra is not sold in the US as far as I know. How many miles on it, does it have a transmission dipstick. Is the fluid low? Has the fluid ever been changed and are you sure the right fluid has been used?

Thanks for reply will have to check that helpful list thank you
