Work Procedure

Check the amount of engine oil. Replenish if necessary. Refer to "INSPECTION ".
Check for leak of the CVT fluid. Refer to "INSPECTION ".
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).
After warming up transaxle assembly, remove oil pressure detection Plug (A) and 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.
Be sure to apply the parking brake and block the tires.
Start the engine.
Measure the line pressure at both idle and the stall speed.

CAUTION: Keep brake pedal pressed all the way down during measurement.

Line pressure: "LINE PRESSURE "
Install O-ring to fluid pressure detection plug after the measurements are complete.
CAUTION:
- Never reuse O-ring.
- Apply CVT fluid to O-ring.
Install oil pressure detection plug and tighten to the specified torque.

RESULT OF INSPECTION

Condition		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
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 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 pressure adjustment function. For example Oil pump wear Line pressure solenoid valve or plug sticking 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.
