16-76 ELECTRICAL SYSTEM
Switches and Sensors
Disconnect the connector [A].
• Remove the fan switch [B].
• Suspend the switch [A] in a container of coolant so that
the temperature–sensing projection and threaded portion
are submerged.
• Suspend an accurate thermometer [B] in the coolant so
that the sensitive portions are located in almost the same
depth.
NOTE
○The switch and thermometer must not touch the container
sides or bottom.
• Place the container over a source of heat and gradually
raise the temperature of the coolant while stirring the
coolant gently.
• Using the hand tester, measure the internal resistance
of the switch across the terminals at the temperatures
shown in the table.
Special Tool - Hand Tester: 57001–1394
If the hand tester does not show the specified values, replace
the switch.
Fan Switch Resistance
Rising temperature:
From OFF to ON at 93 ∼ 103°C (199 ∼ 217°F)
Falling temperature:
Fan stops with the temperature 3 ∼ 8°C(38∼ 46 °F)
lower than the operation temperature range.
ON: Less than 0.5 Ω
OFF: More than 10 MΩ
Water Temperature Sensor Inspection
Remove the fuel tank (see Fuel System (DFI) chapter).
Disconnect the water temperature sensor connector [A].
• Remove the water temperature sensor [B] (see Fuel System
(DFI) chapter).
