Toyota Camry (XV70): Pressure Control Solenoid "H" Actuator Stuck Off (P28167F)
Toyota Camry Repair Manual XV70 (2018-2024) / Drivetrain / Ua80e (automatic Transmission / Transaxle) / Automatic Transaxle System / Pressure Control Solenoid "H" Actuator Stuck Off (P28167F)
DESCRIPTION
Based on signals from the transmission revolution sensors (NT and NC), the actual gear is detected.
The ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical malfunctions of the solenoid valves, transmission valve body assembly and automatic transaxle assembly (clutch, brake, gear, etc.).
Actual gear when solenoid (SL5) valve malfunction occurs (without fail-safe control):|

Lost Communication with ECM/PCM "A" Missing Message (U010087)
DESCRIPTION The engine control unit and transmission control unit are located inside the ECM. The engine control unit intercommunicates with the transmission control unit using CAN communication.
If
Transmission Control Switch Circuit
DESCRIPTION When the shift lever is in S and moved toward "-" or "+", it is possible to select different shift ranges (S1 to S8).
Moving the shift lever toward "+" increases the shift range by one,
Shift Paddle Switch Circuit
DESCRIPTION Moving the shift lever to S enables the shift range to be selected. The shift range can be selected by operating the "+" or "-" shift paddle switch. WIRING DIAGRAM
