AUTOMATIC TRANSAXLE (M13 ENGINE) 7B1-41
Line Pressure Test
Purpose of this test is to check operating conditions of each part
by measuring fluid pressure in fluid pressure line.
Line pressure test requires 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 fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pressure check hole in
transaxle case.

After attaching oil pressure gauge, check that no fluid
leakage exists.
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.
