DTC P0745-13: Pressure Control Solenoid "A" Circuit Open [09/2015 - ]: Description

WARNING: This page is about a different variant/trim than selected.

Changing gears is performed by the ECM turning the shift solenoid valves SL1, SL2, SL3, SL4 and SL5 on and off.

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 vehicle to be driven. If all of the shift solenoid valves are malfunctioning, only the mechanical fluid pressure circuit will function and some manual operation will be possible. If an open or short occurs in a shift solenoid valve circuit, the ECM cuts power to the malfunctioning shift solenoid valve.

HINT: 

The following table shows normal operation of the shift solenoid valve SL1 when the shift lever is in D.
