P0868 on Toyota
Transmission Fluid Pressure Low
P0868 on Toyota vehicles indicates transmission fluid pressure low. Au7o has documented this code across 2 Toyota models — most commonly on C-HR, Corolla. 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 Toyota range from $150 to $4,500, 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
P0868 on Toyota by Model
Toyota C-HR(1 issue)
- CVT Transmission Hesitation and Rubber Band Effect2018-2022
The C-HR's CVT (K120) exhibits noticeable hesitation on acceleration and the typical CVT 'rubber band' effect where engine RPM rises before the vehicle accelerates. The lag between throttle input and forward motion is more pronounced than in competing vehicles.
Toyota Corolla(1 issue)
- CVT Transmission Shudder and Failure2014-2019
The Continuously Variable Transmission (CVT) in 2014-2019 Corollas may experience shuddering, jerking during acceleration, high RPM before shifting, and in severe cases complete transmission failure. Issues are particularly reported when accelerating from a stop or during downshifting. Some owners have experienced catastrophic failures at relatively low mileage.

What does P0868 mean on Toyota?▼
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 Toyota specifically, this code is documented across 2 models.
What causes P0868 on Toyota vehicles?▼
Common causes on Toyota: 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.
