LINE PRESSURE S/V

DESCRIPTION
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".

ON BOARD DIAGNOSIS LOGIC







DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE

CAUTION: If conducting this "DTC CONFIRMATION PROCEDURE" again, always turn ignition switch "OFF" and wait at least 5 seconds before continuing.

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.

OR

With Generic Scan Tool
1) Turn ignition switch "ON".
2) Depress accelerator pedal completely and wait at least 1 second.
3) Select "MODE 7" with GST.

OR

Without Scan Tools
1) Turn ignition switch "ON".
2) Depress accelerator pedal completely and wait at least 1 second.
3) Perform self-diagnosis for ECM.

DIAGNOSTIC PROCEDURE










COMPONENT INSPECTION
Line Pressure Solenoid Valve
- Remove 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 and ground.




Dropping Resistor
- Check resistance between two terminals.

Resistance: 11.2 - 12.8 Ohms
