Kawasaki Ninja Service Manual: Air Intake Solenoid Valve Unit Test

Kawasaki Ninja Service Manual / Electrical System / Air Intake Solenoid Valve / Air Intake Solenoid Valve Unit Test

Remove the air intake solenoid valve (see Air Intake Solenoid Valve Removal in the Fuel System (DFI) chapter).
Set the hand tester [A] to the × 1 Ω range and connect it to the air intake solenoid valve terminals as shown in the figure.

Special Tool - Hand Tester: 57001-1394

Air Intake Solenoid Valve Resistance Standard: 22 26 Ω at 20°C (68°F)

If the resistance reading is out of the specified value, replace it with a new one.

Air Intake Solenoid Valve Unit Test

Connect the 12 V battery [A] to the air intake solenoid valve terminals as shown in the figure.

Air Intake Solenoid Valve Unit Test

Blow the air to the intake air duct [A], and make sure does not flow the blown air from the outlet air duct [B].

Air Intake Solenoid Valve Unit Test

Disconnect the 12 V battery.
Blow the air to the intake air duct [A] again, and make sure flow the blown air from the outlet air duct [B].

If the air intake solenoid valve does not operate as described, replace it with a new one.

NOTE

To check air flow through the air intake solenoid valve, just blow through the air intake solenoid valve hose (intake side) [C].

Wheel/Tire Damage Inspection
Remove any imbedded stones [A] or other foreign particles [B] from tread. Visually inspect the tire for cracks and cuts, and replace the tire if necessary. Swelling or high spots indicate internal damage, requiring tire replacement. Visually inspect the wheel for cracks, cuts and dents ...

Radiator Inspection
Remove the radiator (see Radiator and Radiator Fan Removal). Check the radiator core. If there are obstructions to air flow, remove them. If the corrugated fins [A] are deformed, carefully straighten them. If the air passages of the radiator core are blocked more than 20% by unremovable ...

Precautions
1) No need of topping-up No topping-up is necessary in this battery until it ends its life under normal use. Forcibly prying off the seal cap to add water is very dangerous. Never do that. 2) Refreshing charge. Give refresh charge for 5 to 10 hours with charge current shown in the text (see ...
