LINE PRESSURE SOLENOID VALVEPFP:31940
DescriptionECS004UF
The line pressure solenoid valve regulates the oil pump discharge
pressure to suit the driving condition in response to a signal sent
from the TCM.
The line pressure duty cycle value is not consistent when the
closed throttle position switch is ON. To confirm the line pres-
sure duty cycle at low pressure, the accelerator (throttle)
should be open until the closed throttle position switch is OFF.
CONSULT-II Reference ValueECS00CT5
Remarks: Specification data are reference values.
NOTE:
The line pressure duty cycle value is not consistent when the closed throttle position switch is “ON”. To confirm the line pressure duty
cycle at low pressure, the accelerator (throttle) should be open until the closed throttle position switch is “OFF”.
On Board Diagnosis LogicECS00CT6
Possible CauseECS00CT7
Check the following items.

Harness or connector
(The solenoid circuit is open or shorted.)

Line pressure solenoid valve
DTC Confirmation ProcedureECS00CT8
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and wait at
least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
