LINE PRESSURE SOLENOID VALVE
LINE PRESSURE SOLENOID VALVE
PFP: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
pressure duty cycle at low pressure, the accelerator (throttle)
should be open until the closed throttle position switch is
“OFF”.
CONSULT-II REFERENCE VALUE IN DATA MONITOR MODE
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”.

7. CHECK GROUND CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect A/T device harness connector.
3. Check continuity between A/T device harness connector M58 terminal 6 (B) and ground.
If OK, check harness for short to ground and short to power.
OK or NG
OK >> GO TO 8.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
8. CHECK PARK POSITION SWITCH AND RELAY CIRCUIT (COIL SIDE)
Check continuity between A/T device harness connector M58 terminals 6 (B) and 7 (P).
OK or NG
OK >> GO TO 9.
NG >> Replace park position switch or relay.
9. CHECK SHIFT LOCK SOLENOID AND RELAY CIRCUIT (POINT SIDE)
1. Connect A/T device harness connector.
2. Turn ignition switch to “ON” position.
3. Check operation sound.
OK or NG
OK >> GO TO 10.
NG >> Replace shift lock solenoid or relay.Continuity should exist.

2. Remove air breather hose.
3. Disconnect A/T solenoid valve harness connector, PNP switch harness connector and revolution sensor
harness connector.
4. Remove crankshaft position sensor (Euro-OBD) from transaxle.
5. Disconnect control cable from transaxle.
6. Remove front exhaust tube.
7. Disconnect oil cooler hoses.
8. Remove drive shafts. Refer to FA X - 11 , "
FRONT DRIVE
SHAFT" , RAX-9, "REAR DRIVE SHAFT" .

5. Set manual shaft to position P.
6. Remove park/neutral position (PNP) switch.
7. Remove oil pan and oil pan gasket.
●Do not reuse oil pan bolts.
8. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
●If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-11, "
RADIATOR" .
9. Remove control valve assembly according to the following pro-
cedures.
a. Remove control valve assembly mounting bolts I , X and
●.
b. Remove snap ring from terminal body.
