Judgment Possible cause
Idle speedLow for all positions
(“P”, “R”, “N”, “D”, “L”)Possible causes include malfunctions in the pressure supply system and low oil pump output.
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
 CVT fluid temperature sensor malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (sticking in OFF state, filter
clog, cut line)
 Pressure regulator valve or plug sticking
Stall speedLine pressure does not
rise higher than the
line pressure for idle.Possible causes include a sensor malfunction or malfunction in the pressure adjustment func-
tion.
For example
 Accelerator pedal position signal malfunction
TCM malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (shorting, sticking in ON
state)
 Pressure regulator valve or plug sticking
The pressure rises,
but does not enter the
standard position.Possible causes include malfunctions in the pressure supply system and malfunction in the
pressure adjustment function.
For example
 Accelerator pedal position signal malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (sticking, filter clog)
 Pressure regulator valve or plug sticking
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.

1.CHECK VEHICLE SPEED WHEN SHIFTING GEARS — PART 1
1. Drive vehicle for approximately 10 minutes to warm engine oil and CVT fluid up to operating temperature.
2. Park vehicle on flat surface.
3. Move selector lever to “P” position.
4. Start engine.
5. Move selector lever to “D” position.
6. Accelerate vehicle at 2/8 throttle opening and check “Vehicle
Speed When Shifting Gears”.
With CONSULT-III
- Read vehicle speed and engine speed. Refer to TM-337, "Vehi-
cle Speed When Shifting Gears".
Is the inspection results normal?
YES >> GO TO 2.
NO >> Refer to TM-286, "
Symptom Table". GO TO 2.

2. Push sport mode switch. (Sport mode ON.)
3. Accelerate vehicle at 2/8 throttle opening and check “Vehicle
Speed When Shifting Gears”.
With CONSULT-III
- Read vehicle speed and engine speed. Refer to TM-337, "Vehi-
cle Speed When Shifting Gears".
Is the inspection results normal?
YES >> GO TO 4.
NO >> Refer to TM-286, "
Symptom Table". GO TO 4.
