Kawasaki Ninja Service Manual: Main Throttle Sensor Input Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Main Throttle Sensor (Service Code 11) / Main Throttle Sensor Input Voltage Inspection

NOTE

Be sure the battery is fully charged.

Do not disconnect the connectors of the throttle body assy.

Main Throttle Sensor Input Voltage Inspection


Special Tool - Throttle Sensor Setting Adapter: 57001 -1538

Main Throttle Sensor Input Voltage Inspection


Main Throttle Sensor Input Voltage Connections to Adapter: Digital Meter (+) → W (sensor BL) lead Digital Meter (–) → BK (sensor BR/BK) lead

Input Voltage Standard: DC 4.75 5.25 V


If the reading is within the standard, check the main throttle sensor resistance (see Main Throttle Sensor Resistance Inspection).

If the reading is out of the standard, remove the ECU and check the wiring for continuity between harness connectors.

Special Tool - Hand Tester: 57001-1394

Main Throttle Sensor Input Voltage Inspection


Wiring Continuity Inspection ECU Connector [A] ←→ Main Throttle Sensor Connector [B] BL lead (ECU terminal 9) [C] BR/BK lead (ECU terminal 13) [D]

If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

Main Throttle Sensor Removal/Adjustment
NOTICE Do not remove or adjust the main throttle sensor [A] since it has been adjusted and set with precision at the factory. Never drop the throttle body assy especially on a hard surface. Suc ...

Main Throttle Sensor Resistance Inspection
Turn the ignition switch to OFF. Measure the main throttle sensor resistance in the same way as input voltage inspection, note the following. Disconnect the throttle sensor setting adapter [ ...

Lubrication
Lubrication is necessary after riding through rain or on wet roads, or any time that the chain appears dry. Use a lubricant for sealed chains to prevent deterioration of chain seals. If the chain is especially dirty, clean it using a cleaner for sealed chains following the instructions suppli ...

Bolts, Nuts and Fasteners Tightness Inspection
Check the tightness of the bolts and nuts listed here. Also, check to see that each cotter pin is in place and in good condition. NOTE For the engine fasteners, check the tightness of them when the engine is cold (at room temperature). If there are loose fasteners, retighten them to ...

Brake Line Bleeding
The brake fluid has a very low compression coefficient so that almost all the movement of the brake lever or pedal is transmitted directly to the caliper for braking action. Air, however, is easily compressed. When air enters the brake lines, brake lever or pedal movement will be partially used ...
