Toyota Camry Repair Manual XV70 (2018-2024) / Drivetrain / Ua80e (automatic Transmission / Transaxle) / Automatic Transaxle System / Pressure Control Solenoid "A" Actuator Stuck Off (P07457F)
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 (SL1) valve malfunction occurs (without fail-safe control):|
