General Information

P0773 Shift Control Solenoid Valve \'E\' Electrical (Low Coast Brake Solenoid)

General Information

Component Location





General Description

This solenoid valve is operating with duty by PCM for reducing the shift shock when pressure goes to RED element.

DTC Description

The TCM checks the Shift Control Signal by monitoring the feedback signal from the solenoid valve drive circuit. If an unexpected signal is monitored (for example, high voltage is detected when low voltage is expected, or low voltage is detected when high voltage is expected), the TCM judges that this solenoid circuit is malfunctioning and sets this code.
