O P
The CVT fluid temperature rises in the range of 50 - 80
°C (122 - 176 °F) during 10 minutes of driving.
3. After warming up CVT, remove the oil pressure detection plug and install the oil pressure gauge [special service tool: - (OTC3492)].
CAUTION:
When using the oil pressure gauge, be sure to use the O-ring attached to the oil pressure detec-
tion plug.
4. Securely engage the parking brake so that the tires do not turn.
5. Start the engine, and then measure the line pressure at both idle and the stall speed.
CAUTION:
• Keep the brake pedal pressed all the way down during
measurement.
• When measuring the line pressure at the stall speed, refer
to "STALL TEST" .
6. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque below.
CAUTION:
• Do not reuse O-ring.
• Apply CVT fluid to O-ring.

TROUBLE DIAGNOSIS
Road Test INFOID:0000000004666886
DESCRIPTION
• The purpose of the test is to determine overall performance of CVT and analyze causes of problems.
• The road test consists of the following three parts:
1. “Check Before Engine Is Started” CVT-45 .
2. “Check at Idle” CVT-45 .
3. “Cruise Test” CVT-47 .
Judgement Possible cause
Idle speed Low 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
position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
High Possible 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 speed Line 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 pres-
sure 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
position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve. SAT786A
