Hi, I'm new to this forum. I have a 2012 Nissan Versa (CVT). My engine light recently came on, not blinking, but stays lit. I took it to AutoZone to have the code read and is reading P0846, which refers to:

Transmission Fluid Pressure Sensor/Switch "B" Circuit Range/Performance

I'm not good with cars but I work people who do work on their cars/trucks all the time, although not familiar with CVT.

They tried to check my tranny fluid as a starting point, but couldn't find a dipstick. I know that my Versa requires a special fluid which isn't a problem, but how to you change the fluid with No Dipstick?

So really what I need to know is how can I check / change the tranny fluid, and will this solve that problem and get my engine light to go off?

Any input is HIGHLY APPRECIATED! I know I could take it to the dealer, but what like to know how it is done. Thanks

Ok, so two days after this post my car died. I had it towed to the shop. They said the previous code was NOT found, but that the engine misfired, lean fuel and air. Need spark plugs replaced, reset idle air volume, reset codes. Also that brake switch tells my car its consistantly braking...?...? Tranny fluid flush and fill...$1400!!! Yowza... And my car is only 2.5 years old with 100,000 miles.

i ran into the same p0846 code, transmission was slipping rpm would jump back and forth between 3th and 4th. I took it to the dealership and they ended up replacing the valve body which included that fluid pressure sensor(the fluid pressure sensor is inside the valve body) dealership charged $1600 for installing the new valve body plus labor, i only paid half being that nissan consumer affairs covered 50 percent. i had 112,000 miles when i got that code.
