Nissan Quest E52. Manual - part 1209

TM-66

< BASIC INSPECTION >

[CVT: RE0F09B]

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 
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 posi-
tion.

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 posi-
tion

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:0000000009650116

• 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.

TM-67, "Check before Engine Is Started"

2.

TM-67, "Check at Idle"

3.

TM-68, "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.
