NO
Check for open in harness. Repair as necessary and go to "VERIFICATION OF VEHICLE
REPAIR" procedure.
2. Check signal circuit short inspection
1. Ignition "OFF".
2. Disconnect "A/T SOLENOID VALVE" connector and "PCM/TCM" connector.
3. Measure resistance between terminal "9" of the ATM SOLENOID VALVE harness and chassis
ground.
Specification: Infinite

4. Is resistance within specifications?
YES
Go to "COMPONENT INSPECTION" procedure.
NO
Check for short to ground in harness. Repair as necessary and go to "VERIFICATION OF
VEHICLE REPAIR" procedure.
COMPONENT INSPECTION
1. CHECK SOLENOID VALVE
1. Ignition "OFF".
2. Disconnect "A/T SOLENOID VALVE" connector.
3. Measure resistance between terminal "6" and terminal "9" of the ATM SOLENOID VALVE
harness connector.
Specification: Approximately 2.7-3.4 ohms [20°C (68°F)]

DTC P0748 PRESSURE CONTROL SOLENOID VALVE A - ELECTRICAL
COMPONENT LOCATION

GENERAL DESCRIPTION
Variable Force 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 the width of the oil passage.
DTC DESCRIPTION
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 detected when high voltage is expected), the TCM judges that the Low and Reverse
control solenoid circuit is malfunctioning and sets this code.
