Oil Temperature Sensor Removal/Installation

CAUTION

Never drop the sensor, especially on a hard surface.

Such a shock to the sensor can damage it.

•Remove:

Engine (see Engine Removal/Installation chapter)

Oil Temperature Sensor [A]

•Fill the hollow of the oil pan [A] with the specified silicone grease [B] as shown, before installing the oil temperature sensor [C].

[D]5 mm (0.2 in.)

Silicone Grease-Kawasaki Bond: 92137-1002

•Tighten:

Output Voltage Inspection

NOTE

○Be sure the battery is fully charged.

•Remove the ECU (see this chapter). Do not disconnect the connector.

•Connect a digital voltmeter [A] to the ECU connector [B], with the needle adapter set.

Special Tool - Needle Adapter Set: 57001-1457

Water Temperature Sensor Output Voltage

Connections to ECU

Meter (+) → Y lead (terminal 37)

Meter (–) → BK/W lead (terminal 8)

•Turn the ignition switch ON and push the lanyard key un- der the stop button.

•Pushing the start button, run the engine 5 ∼ 6 seconds at idling to measure the sensor output voltage.

○Wait 15 seconds before using the starter again.

Output Voltage at ECU

Standard: about 3 ∼ 4 V at 20°C (68°F)

NOTE

○The output voltage changes according to the oil temper- ature in the engine.
