DTC P0748 PRESSURE CONTROL SOLENOID VALVE A - ELECTRICAL
COMPONENT LOCATION
EC6BF3EE
Refer to DTC P0743.
GENERAL DESCRIPTION
E363780E
Variable Faced Solenoid (Linear Solenoid) : With the duty control which uses higher frequency(600Hz), instead of the
existing PWM type which adapts low frequency(60Hz) to control, spool valve can be controlled precisely.
In PWM control, the amount of oil flow is determined by the duration of "ON"signal among continuously repeated ON/OFF
signals.
In VFS, the amount is decided by how widely spool valve open the passage of going through.
DTC DESCRIPTION
EE1EC5BB
The TCM checks the VFS 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 de-
tected when high voltage is expected), the TCM judges that the Low and Reverse control solenoid circuit is malfunctioning
and sets this code.
DTC DETECTING CONDITION
E12CA0CF
Item
Detecting Condition
Possible cause
DTC Strategy
• Check voltage range
Enable Conditions
• 16V > Voltage Battery >11V
• In gear state(no gear shifting) 500msec is
passed from turn on the relay
• A/T Relay = ON
• Engine state = RUN
Threshold value
• Out of available voltage range
Diagnostic Time
• More than 2 seconds
Fail Safe
• Locked in 3rd gear (Control relay off)
• Open or short in circuit
• Faulty VFS SOLENOID
VALVE
• Faulty PCM/TCM
