14-56 ELECTRICAL SYSTEM

Sensors

Throttle Sensor Inspection

•Referter. to Throttle Sensor Section in the Fuel System chap-

Water Temperature Sensor Inspection

•Remove the water temperature sensor (see Feul (DFI) System chapter).

•Suspend the sensor [A] in a container of water so that the temperature-sensing projection is submerged.

•Suspend an accurate thermometer [B] in the water.

NOTE

○The sensor and thermometer must not touch the con- tainer side or bottom.

•Place the container over a source of heat and gradually raise the temperature of the water while stirring the water gently.

•Using the hand tester, measure the internal resistance of the sensor at the temperatures shown in the table.

If the hand tester does not show the specified values, re- place the sensor.

Water Temperature Sensor Resistance

Water Temperature	Sensor Resistance
20°C (68°F)	approx.	293 kΩ
50°C (122°F)	approx.	78.5	kΩ
90°C (194°F)	approx.	18.1	kΩ
100°C (212°F)	approx.	13.2	kΩ

Inlet Air Temperature Sensor Inspection

•Refer to Inlet Air Temperature Sensor Section in the Fuel System chapter.

Oil Temperature Sensor Inspection

•Remove the oil temperature sensor (see Feul (DFI) Sys- tem chapter).

•Suspend the sensor [A] in a container of water so that the temperature-sensing projection is submerged.

•Suspend an accurate thermometer [B] in the water.

NOTE

○The sensor and thermometer must not touch the con- tainer side or bottom.

•Place the container over a source of heat and gradually raise the temperature of the water while stirring the water gently.

•Using the hand tester, measure the internal resistance of the sensor at the temperatures shown in the table.

If the hand tester does not show the specified values, re- place the sensor.
