Kawasaki Ninja Service Manual / Self-Diagnosis System / Self-Diagnosis / Backups






(1): D-J Method: When the engine load is light like at idling or low speed, the ECU determines the injection quantity by calculating from the throttle vacuum (vacuum sensor output voltage) and engine speed (crankshaft sensor output voltage). This method is called D-J method.

(2): α-N Method: As the engine speed increases, and the engine load turns middle to heavy, the ECU determines the injection quantity by calculating from the throttle opening (throttle sensor output voltage) and the engine speed. This method is called α-N method.

*: This depends on the number of stopped cylinders.

The main throttle sensor is a rotating variable resistor that change output voltage according to throttle operating. The ECU senses this voltage change and determines fuel injection quantity, and ignition timing according to engine rpm, and throttle opening.

Camshaft Runout Inspection
Remove the camshafts (see Camshaft Removal). Set the camshaft in a camshaft alignment jig or on V blocks. Measure the runout with a dial gauge at the specified place as shown in the figure. If the runout exceeds the service limit, replace the camshaft. Camshaft Runout Standard: TIR ...
