DTC P0775-13: Pressure Control Solenoid "B" Circuit Open [10/2017 - ]: Description
WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 350, 2023 Lexus IS 300, and 2022 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
Shifting from 1st to 6th is performed in combination with the ON and OFF operation of shift solenoid valves SL1, SL2, S1, S2, S3, S4 and SR which is controlled by the ECM. If an open or short occurs in any of the shift solenoid valve circuits, the ECM controls the remaining normal shift solenoid valves to allow the gears to be operated safely.
