INSPECTION

1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the

CVT fluid temperature is 50 to 80

°C (122 to 176°F). Inspect the

amount of CVT fluid. Replenish if necessary.

3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test.

NOTE:

It is good practice to mark the point of specified engine rpm on

indicator.

5. Start engine, apply foot brake, and place selector lever in “D”

position.

6. While holding down the foot brake, gradually press down the

accelerator pedal.

7. Quickly read off the stall speed, and then quickly remove your

foot from the accelerator pedal.

CAUTION:

Never hold down the accelerator pedal for more than 5 sec-

onds during this test.

8. Move the selector lever to the “N” position.

9. Cool down the CVT fluid.

CAUTION:

Run the engine at idle for at least 1 minute.

10. Repeat steps 6 through 9 with selector lever in “R” position.

Line Pressure Test Procedure

1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80

°C

(122 to 176

°F), then inspect the amount of CVT fluid and replenish if necessary.

NOTE:

The CVT fluid temperature rises in the range of 50 to 80

°C (122 to 176°F) during 10 minutes of driv-

ing.

3. After warming up CVT, remove the oil pressure detection plug

and install the joint pipe adapter (SST: KV31103600) (A),

adapter (SST: 25054000) (B), oil pressure gauge set (commer-

cial service tool) (C).

CAUTION:

When using the oil pressure gauge, be sure to use the O-

ring attached to the oil pressure detection 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 

TM-226, "Inspection and Judgment"

. 

6. After the measurements are complete, install the oil pressure

detection plug and tighten to the specified torque below.

CAUTION:

• Never reuse O-ring.

• Apply CVT fluid to O-ring.

Judgment Possible 

cause

Idle speed

Low for all positions 
(“P”, “R”, “N”, “D”)

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 spe-
cific 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 func-
tion.
For example
• Accelerator pedal position signal malfunction
• CVT fluid temperature sensor malfunction
• 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 function.
For example
• Accelerator pedal position signal malfunction
• TCM malfunction
• Line pressure solenoid malfunction (shorting, sticking in ON state)
• Pressure regulator valve or plug sticking

The pressure rises, 
but does not enter 
the standard posi-
tion.

Possible causes include malfunctions in the pressure supply system and malfunction in the pres-
sure adjustment function.
For example
• Accelerator pedal position signal malfunction
• Line pressure solenoid malfunction (sticking, filter clog)
• Pressure regulator valve or plug sticking

Only low for a spe-
cific 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.
