INSPECTION
1. DRAIN ENGINE COOLANT
2. INSPECT NO.1 ECT SWITCH
(a) Remove the No.1 ECT switch.
(b) Inspect the No.1 ECT switch.
(1) Using an ohmmeter, check that there is no continu-
ity between the terminals when the coolant temper-
ature is above 98°C (208°F).
If there is continuity, replace the switch.
(2) Check that there is continuity, between the termi-
nals when the coolant temperature is below 88°C
(190°F).
If there is no continuity, replace the switch.
(c) Reinstall the No.1 ECT switch.
3. INSPECT NO.2 ECT SWITCH
(a) Remove the No.2 ECT switch.
(b) Inspect the No.2 ECT switch.
(1) Using an ohmmeter, check that there is continuity
between terminals when the coolant temperature is
above 94°C (201°F).
If there is no continuity, replace the switch.
(2) Check that there is no continuity between the termi-
nals when the coolant temperature is below 83°C
(181°F).
If there is continuity, replace the switch.
(c) Reinstall the No.2 ECT switch.
