The probable causes are faulty pressure delivery system, low output
of oil pump, etc.
For example:
a. Wear of oil pump
b. Sticking of pressure regulator valve or plug, spring fatigue
c. Fluid pressure leakage from oil strainer →oil pump→pressure
regulator valve passage
d. Engine idling is too low
The probable cause is fluid pressure leakage of range related
device or passage after the pressure is distributed by the manual
valve.
The probable cause are faulty sensors or poor pressure regulation.
For example:
a. Faulty accelerator sensor
b. Faulty fluid temperature sensor
c. Line pressure solenoid malfunction (sticking, clogging of filter,
short during OFF)
d. Sticking of pressure regulator valve or plug
The probable cause are faulty sensors or poor pressure regulation.
