LINE PRESSURE TEST
Line Pressure Test Port
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the ATF reaches in range of 50 to 80°C (122 to
176 °F), then inspect the amount of ATF and replenish if necessary.
NOTE:
The A/T fluid temperature rises in range of 50 to 80°C (122 to 176 °F) during 10 minutes of driving.
3. Remove the front propeller shaft from vehicle (with AWD models). Refer to PR-4, "
Removal and Installa-
tion".
4. After warming up remove the oil pressure detection plug and install the oil pressure gauge [ST2505S001(J-34301-C)].
CAUTION:
When using the oil pressure ga uge, be sure to use the O-
ring attached to the oil pressure detection plug.
