STALL TEST

Inspection and Judgment

INFOID:0000000009949073

INSPECTION

1.

Inspect the amount of engine oil. Replenish the engine oil if necessary. Refer to 

LU-8, "Inspection"

.

2.

After engine warms up, drive the vehicle in an urban area for approximately 10 minutes.
NOTE:
When ambient temperature is 20

°

C (68

°

F), it takes about 10 minutes for the CVT fluid to warm up to 50 to

80

°

C (122 to 176

°

F).

3.

Inspect the amount of CVT fluid. Replenish if necessary.

4.

Securely engage parking brake so that the tires do not turn.

5.

Start the engine.

6.

Apply foot brake, and shift selector lever to “D” position.

7.

Gradually press down accelerator pedal while holding down the foot brake.

8.

Quickly read off the stall speed, and then quickly remove your foot from accelerator pedal.

CAUTION:

Never hold down accelerator pedal for more than 5 seconds during this test.

9.

Shift selector lever to “N” position.

10. Cool down the CVT fluid.

CAUTION:

Run the engine at idle for at least 1 minute.

11. Repeat steps 7 through 10 with selector lever in “R” position.

JUDGMENT

• O: Stall speed within standard value position.

• H: Stall speed is higher than standard value.

• L: Stall speed is lower than standard value.

3.

Inspect the amount of CVT fluid. Replenish if necessary.

4.

Remove oil pressure detection plug (A).

5.

Install oil pressure gauge [special service tool: — (OTC3492)].
NOTE:
When using oil pressure gauge, be sure to use O-ring attached
to oil pressure detection plug.

6.

Securely engage parking brake so that the tires do not turn.

7.

Start the engine.

8.

Measure the line pressure at both idle and the stall speed.

CAUTION:

Keep brake pedal pressed all the way down during mea-
surement.

9.

Install O-rig to oil pressure detection plug.

CAUTION:

• Never reuse O-ring.
• Apply CVT fluid to O-ring.

10. Install oil pressure detection plug.

Judgment 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
• Line pressure solenoid malfunction (sticking in OFF state, filter clog, cut line)
• Pressure regulator valve or plug sticking

LINE PRESSURE TEST

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
• 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
• 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.

ROAD TEST

Description

INFOID:0000000009949075

DESCRIPTION

• The purpose of the test is to determine the overall performance of CVT and analyze causes of problems.
• The road test consists of the following three parts:

1.

“Check Before Engine Is Started”

2.

“Check at Idle”

3.

“Cruise Test”

• Before the road test, familiarize yourself with all test procedures and items to check.
• Perform tests for all the check items until a malfunction phenomenon is detected. Perform diagnosis for NG

items after the completion of road tests. Refer to 

TM-188, "Symptom Table"

.
