P0868 on Infiniti
Transmission Fluid Pressure Low
P0868 on Infiniti vehicles indicates transmission fluid pressure low. Au7o has documented this code across 1 Infiniti model — most commonly on QX60. This code indicates the transmission's internal fluid pressure is reading lower than the computer expects for current operating conditions. The transmission control module uses a pressure sensor to monitor line pressure, which is what applies the clutches and bands that engage gears. When that pressure stays below the target threshold, P0868 sets. Low line pressure can cause slipping, harsh or delayed shifts, and in severe cases internal clutch damage, so it should be addressed promptly. Typical repair costs on Infiniti range from $3,000 to $8,000, depending on the specific model and root cause.
Common Causes of P0868
- •Low transmission fluid level
- •Worn or stuck-open pressure control solenoid
- •Internal leak (worn seals, gaskets, or valve body)
- •Faulty transmission fluid pressure sensor
- •Clogged transmission filter
- •Failing transmission (oil) pump
- •Worn or leaking valve body
- •Wiring or connector fault to the pressure sensor/solenoid

Infiniti QX60(1 issue)
- CVT Transmission Failure2013-2020
The Jatco CVT in the QX60 is prone to premature failure, particularly in the 2013-2017 models. The transmission overheats during towing or sustained highway driving, leading to shuddering, slipping, and eventual complete failure.

What does P0868 mean on Infiniti?▼
P0868 stands for "Transmission Fluid Pressure Low." This code indicates the transmission's internal fluid pressure is reading lower than the computer expects for current operating conditions. The transmission control module uses a pressure sensor to monitor line pressure, which is what applies the clutches and bands that engage gears. When that pressure stays below the target threshold, P0868 sets. Low line pressure can cause slipping, harsh or delayed shifts, and in severe cases internal clutch damage, so it should be addressed promptly. On Infiniti specifically, this code is documented across 1 model.
What causes P0868 on Infiniti vehicles?▼
Common causes on Infiniti: Low transmission fluid level, Worn or stuck-open pressure control solenoid, Internal leak (worn seals, gaskets, or valve body), Faulty transmission fluid pressure sensor, Clogged transmission filter. Specific causes vary by model and year — see the per-model sections below.
