P0867 is an OBD-II diagnostic trouble code meaning “Transmission Fluid Pressure.” This generic powertrain code indicates the transmission control module detected that the measured transmission fluid (line) pressure is outside the expected range. Proper hydraulic pressure is essential for applying clutches and bands and for smooth, correctly timed shifts, so an out-of-range reading can cause shifting problems. Causes often trace to fluid condition or level, internal hydraulic issues, or a faulty pressure sensor. This code is most commonly reported on 2019-2021 Hyundai Veloster (2.0, 2.0 Premium), and 2021-2023 Kia Rio, with repair costs ranging from $150 to $5,500.
