P0841 on Nissan
Transmission Fluid Pressure Sensor/Switch "A" Circuit Range/Performance
P0841 on Nissan vehicles indicates transmission fluid pressure sensor/switch "a" circuit range/performance. Au7o has documented this code across 1 Nissan model — most commonly on Maxima. This powertrain code means the transmission computer detected the 'A' transmission fluid pressure sensor or switch reading out of its expected range or not matching actual operating conditions. This sensor converts hydraulic line pressure into an electrical signal the computer uses to manage shift timing and quality. An out-of-range reading can cause incorrect shift behavior, harsh or slipping shifts, or limp mode. It should be addressed to prevent drivability problems and possible transmission damage. Typical repair costs on Nissan range from $200 to $5,500, depending on the specific model and root cause.
Common Causes of P0841
- •Low or contaminated transmission fluid
- •Faulty transmission fluid pressure sensor/switch
- •Wiring or connector problems in the sensor circuit
- •Clogged filter or restricted fluid passages
- •Worn valve body or internal pressure control fault
- •Faulty transmission control module (less common)
P0841 on Nissan by Model
Nissan Maxima(1 issue)
- CVT Belt Slip at High Mileage2009-2023
The Maxima equipped with the Jatco CVT experiences progressive belt slip as mileage increases, typically becoming noticeable after 100,000-130,000 miles. The steel push belt loses grip on the pulleys, causing delayed acceleration response, RPM flare under load, and a rubber-band effect. Heavy acceleration and towing/heavy loads accelerate wear. Unlike the Altima/Rogue CVT issues that often manifest earlier, the Maxima CVT tends to last longer but still develops this wear pattern.

What does P0841 mean on Nissan?▼
P0841 stands for "Transmission Fluid Pressure Sensor/Switch "A" Circuit Range/Performance." This powertrain code means the transmission computer detected the 'A' transmission fluid pressure sensor or switch reading out of its expected range or not matching actual operating conditions. This sensor converts hydraulic line pressure into an electrical signal the computer uses to manage shift timing and quality. An out-of-range reading can cause incorrect shift behavior, harsh or slipping shifts, or limp mode. It should be addressed to prevent drivability problems and possible transmission damage. On Nissan specifically, this code is documented across 1 model.
