Line Pressure
Judgement of Line Pressure Test
Engine speedLine pressure [kPa (kg/cm
2 , psi)]
“R” position “D”, “M” positions
At idle speed 425 - 465 (4.3 - 4.7, 62 - 67) 379 - 428 (3.9 - 4.4, 55 - 62)
At stall speed 1,605 - 1,950 (16.4 - 19.9, 233 - 283) 1,310 - 1,500 (13.4 - 15.3, 190 - 218)
Judgement Possible cause
Idle speedLow for all positions
(“P”, “R”, “N”, “D”, “M”)Possible causes include malfunctions in the pressure supply system and low oil pump out-
put.
For example
Oil pump wear
Pressure regulator valve or plug sticking or spring fatigue
Oil strainer oil pump pressure regulator valve passage oil leak
Engine idle speed too low
Only low for a specific
positionPossible causes include an oil pressure leak in a passage or device related to the position
after the pressure is distributed by the manual valve.
HighPossible causes include a sensor malfunction or malfunction in the line pressure adjustment
function.
For example
Accelerator pedal position signal malfunction
A/T fluid temperature sensor malfunction
Line pressure solenoid malfunction (sticking in OFF state, filter clog, cut line)
Pressure regulator valve or plug sticking
Stall speedOil pressure does not
rise higher than the oil
pressure for idle.Possible causes include a sensor malfunction or malfunction in the pressure adjustment
function.
For example
Accelerator pedal position signal malfunction
TCM breakdown
Line pressure solenoid malfunction (shorting, sticking in ON state)
Pressure regulator valve or plug sticking
Pilot valve sticking or pilot filter clogged
The pressure rises, but
does not enter the stan-
dard position.Possible causes include malfunctions in the pressure supply system and malfunction in the
pressure adjustment function.
For example
Accelerator pedal position signal malfunction
Line pressure solenoid malfunction (sticking, filter clog)
Pressure regulator valve or plug sticking
Pilot valve sticking or pilot filter clogged
Only low for a specific
positionPossible causes include an oil pressure leak in a passage or device related to the position
after the pressure is distributed by the manual valve.
