DTC P0748 Pressure Control Solenoid "A" Electrical (Shift Solenoid Valve SL1): Description

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

Shifting from 1st to 5th is performed in combination with "ON" and "OFF" operation of the shift solenoid valves SL1, SL2, SL3, S4 and SR which are controlled by the ECM. If an open or short circuit occurs in either of the shift solenoid valves, the ECM controls the remaining normal shift solenoid valves to allow the vehicle to be operated smoothly (Fail safe function).
