Automatic Transmission/Transaxle: 5A-35
Line Pressure Test
S3RH0A5104015
Purpose of this test is to check operating conditions of
each part by measuring fluid pressure in fluid pressure
line.
Line pressure test requires the following conditions.
• Automatic fluid is at normal operating temperature (70
– 80
°
C / 158 – 176
°
F).
• Fluid is replenished to proper level between FULL and
LOW on dipstick.
• Air conditioner switch is turned OFF.
1) Apply parking brake securely and place chocks
against wheels.
2) Remove right side engine under cover.
3) Remove fluid pressure check hole plug bolt.
4) Attach oil pressure gauge to fluid pressure check
hole in transaxle case.
Special tool
(A): 09925-37811-001
CAUTION
!
After attaching oil pressure gauge, check that
no fluid leakage exists.
5) Depress foot brake fully, run engine at idle and stall
then check fluid pressure in “D” or “R” range.
CAUTION
!
• Do not continue running engine at stall
speed longer than 5 seconds.
• After performing line pressure test, be sure
to leave engine running at idle for longer
than one minute before performing another
line pressure test.
