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].

Valve Clearance
Valve and valve seat wear decreases valve clearance, upsetting valve timing. NOTICE If valve clearance is left unadjusted, wear will eventually cause the valves to remain partly open; which lowers performance, burns the valves and valve seats, and may cause serious engine damage. Valve cle ...
