4. Securely engage the parking brake so that the tires do not turn.
5. Start the engine, then measure the line pressure at both idle and
the stall speed.
CAUTION:
lKeep the brake pedal pressed all the way down during
measurement.
lWhen measuring the line pressure at the stall speed.
Refer toAT-43, "
STALL TEST".
6. After the measurements are complete, install the oil pressure
detection plug and tighten to the specified torque. Refer toAT-
251, "Components".
CAUTION:
lDo not reuse O-ring.
lApply ATF to O-ring.

Judgement Possible cause
Idle speedLow for all positions
(“P”, “R”, “N” and “D”)Possible causes include malfunctions in the pressure supply system and low oil pump output.
For example
lOil pump wear
lPressure regulator valve or plug sticking or spring fatigue
lOil strainer
oil pump
pressure regulator valve passage oil leak
lEngine 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
lAccelerator pedal position signal malfunction
lA/T fluid temperature sensor malfunction
lLine pressure solenoid malfunction (sticking in OFF state, filter clog, cut line)
lPressure regulator valve or plug sticking
