< BASIC INSPECTION >[CVT: RE0F11A]
LINE PRESSURE TEST
LINE PRESSURE TEST
Work ProcedureINFOID:0000000012431049
INSPECTION
1. Check the engine oil level. Replenish if necessary. Refer to
LU-7, "Inspection".
2. Check for CVT fluid leaks. Refer to TM-228, "
Inspection".
3. 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).
4. Stop the vehicle, apply the parking brake and block the tires.
5. Start the engine.
6. Select “Data Monitor” in “TRANSMISSION”.
7. Select “LINE PRESSURE”.
8. Measure the line pressure at both idle and the stall speed. CAUTION:
Keep brake pedal pressed all the way down during measurement.
NARROWING-DOWN MALFUNCTIONING PARTS
Line pressure : TM-265, "Line Pressure"
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
• Damage of chain and sprocket
• 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
Stal l s pe ed 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:
•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:
• Oil pump wear
• 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.
