10th Judgement Flicker
DescriptionThe 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".

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT
1. Turn ignition switch "ON" and select "DATA MONITOR" mode for "ENGINE" with CONSULT.
2. Depress accelerator pedal completely and wait at least 1 second.
With GST
1. Turn ignition switch "ON".
2. Depress accelerator pedal completely and wait at least 1 second.
3. Select "MODE 7" with GST.
No Tools
1. Turn ignition switch "ON".
2. Depress accelerator pedal completely and wait at least 1 second.
3. Perform self-diagnosis for ECM.
Refer to Powertrain Management; Computers and Control Systems.
DIAGNOSTIC PROCEDURE
COMPONENT INSPECTION
Line Pressure Solenoid Valve
Resistance check
Check resistance between two terminals.
Operation check
Check solenoid valve by listening for its operating sound while applying battery voltage to the terminal 6 and ground.
Dropping Resistor
Check resistance between two terminals.
Resistance: 11.2 - 12.8 ohms
