The Pressure Control Solenoid Valve A ( PCSV A ) converts the electric signals, which are controlled by the TCM, into hyraulic pressure. The PCSV A controls the hydraulic pressure, which is applied to the Clutches and Brakes, to reduce the shift shock during shifting.
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 A drive circuit is malfunctioning and sets this code.
Item | Detecting Condition & Limp Home | Possible Cause |
