DTC P2807-13: Pressure Control Solenoid "G" Circuit Open [08/2015 - ]: Description
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2024 Lexus IS 300, 2023 Lexus IS 300, 2022 Lexus IS 300, 2021 Lexus IS 300, and 2020 Lexus IS 300. However, it is still accessible from the selected car via links, so may be relevant.
Based on the ON-OFF combinations of the solenoid (SL1, SL2, SL3, SL4 and SL5) valves, the ECM performs gear shifts from 1st gear to 8th gear.
If a circuit related to a solenoid valve is open or shorted, the ECM uses the fail-safe function to turn other solenoid valves ON or OFF. If all solenoid valves are malfunctioning, only the mechanical fluid pressure circuit will function and some manual operation will be possible. If an open or short has occurred, the ECM cuts power to the malfunctioning solenoid valve.
HINT:
The following table shows normal operation of the solenoid (SL4) valve when the shift lever is in D.
