Component Location
General Description

The Pressure Control Solenoid Valve B ( PCSV B ) converts the electric signals, which are controlled by the TCM, into hyraulic pressure. The PCSV B is designed to control the Rear Clutch and related skip shift from 4th to 2nd or from 2nd to 4th.

DTC Description

The TCM checks the Pressure Control Solenoid Valve signals by monitoring the feedback signals 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 the PCSV B drive circuit is malfunctioning and sets this code.
