2. Inspection and Adjustment
2.4 Sensor Inspection
2.4.1 Oil pressure switch
Disconnect the connector from the oil pressure switch.
Keep the voltammeter probes in contact with the
switch terminal and cylinder block while operating the
engine. It is abnormal if circuit is closed.
2.4.2 Thermo switch
Place the thermo switch in a container filled
with antifreeze or oil. Heat it while measuring
the fluid temperature. The switch is normal if
the voltammeter shows continuity when the fluid
temperature is 107 113 deg C.
2.5 Water leak check in cooling water system
Check coolant water leakage from the cooling water
system visually. If any problem is found, Inspect as
follows.
1) Fill coolant water to the normal level in the
radiator, and install the cap tester on the radiator.
2) Operate the manual pump to set the pressure to
0.09 0.015MPa (0.9 0.15kgf/cm
2
). If the cap
tester pressure gage reading drops then, water is
leaking from the cooling water system. Check
the water leaking point.
