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 [ ...

Check 3-5: Warning Indicator Light (Red LED) (Oil Pressure Warning) Inspection
Connect the leads in the same circuit as Check 3-2. Connect the terminal [10] to the battery (–) terminal. Check that the oil pressure warning symbol [A] and the warning indicator light (Red LED) [B] go on. If the indicator light does not go on, replace the meter unit. ...

Brake Fluid Level Inspection
Check that the brake fluid level in the front brake reservoir [A] is above the lower level line [B]. NOTE Hold the reservoir horizontal by turning the handlebar when checking brake fluid level. If the fluid level is lower than the lower level line, fill the reservoir to the upper lev ...

Brake Pedal Position Adjustment
NOTE Usually it is not necessary to adjust the pedal position, but always adjust it when push rod locknut has been loosened. Loosen the locknut [A] and turn the push rod with the hex head [B] to achieve the correct pedal position. If the length [C] shown is 69 ±1 mm (2.7 ±0.04 in.), th ...
