1. Remove the oil pressure switch 1.
2. Check the conductivity of the oil pressure switch. Replace
it if it is not conductive.
3. Connect the vacuum/pressure gauge to the oil pressure
switch.
Vacuum/Pressure Gauge:
P/N. 3AC-99020-1
Oil Pressure Switch Pressure:
0.029 to 0.049 MPa (4.2 to 7.1 PSI)
[0.3 to 0.5 kgf/cm
2
]
Oil Pressure Switch:
8 N·m (6 lb·ft) [0.8 kgf·m]
7) Inspection of the Oil Pressure Switch
Remove the part to test it as a separate unit.
4. Apply pressure slowly with the vacuum/pressure gauge.
5. Check that the oil pressure switch is not conductive at the
specified pressure. Replace it if it is conductive.
6. Reinstall the oil pressure switch and tighten to the
specified torque.
Apply a screw locking agent (ThreeBond 1327)
on the threaded section of the oil pressure switch
and apply silicone grease on the screw of oil
pressure switch lead wire.
