Description
NCAT0061
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”.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NCAT0061S04
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” 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-II
1)
Turn ignition switch “ON” and select “DATA MONITOR” mode
for “ENGINE” with CONSULT-II.
2)
Depress accelerator pedal completely and wait at least 5 sec-
onds.
If the check result is “NG”, go to “Diagnostic Procedure”,
AT-77.
With GST
Follow the procedure “With CONSULT-II”.
