P0868 on Kia
Transmission Fluid Pressure Low
P0868 on Kia vehicles indicates transmission fluid pressure low. Au7o has documented this code across 2 Kia models — most commonly on Forte, Seltos. 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.
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 Kia by Model
Kia Forte(1 issue)
- CVT Shudder and Hesitation Under Acceleration2019-2024
The IVT (Intelligent Variable Transmission, Kia's name for their CVT) in the 2019-2024 Forte develops a shuddering sensation during light-to-moderate acceleration, particularly from stops and at speeds between 20-45 mph. The issue is caused by the CVT chain and pulley interface wearing irregularly. Kia has released multiple software updates to improve shift mapping and reduce the shudder sensation.
Kia Seltos(1 issue)
- CVT Hesitation and Jerking Under Load2021-2025
The Seltos equipped with the 2.0L engine and CVT (IVT) exhibits hesitation, jerking, and poor acceleration response, particularly when merging or climbing hills. The CVT struggles under load and can enter limp mode. Owners report the transmission feels sluggish compared to traditional automatics. Kia has released TCU software updates to improve response.

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