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.

Turn the ignition switch to OFF.
Remove the throttle body assy (see Throttle Body Assy Removal in the Fuel System (DFI) chapter).

Do not disconnect the connectors of the throttle body assy.

Main Throttle Sensor Input Voltage Inspection

Disconnect the main throttle sensor connector [A].
Connect the setting adapter [A] between the harness connector and main throttle sensor connector.

Special Tool - Throttle Sensor Setting Adapter: 57001 -1538

Main Throttle Sensor Input Voltage Inspection

Connect a digital meter to the setting adapter leads.

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

Measure the input voltage with the engine stopped and with the connector joined.
Connect the following parts to harness connectors temporarily.

ECU Intake Air Temperature Sensor
Turn the ignition switch to ON.

Input Voltage Standard: DC 4.75 5.25 V

Turn the ignition switch to OFF.

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

Disconnect the ECU and sensor connectors.

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 [ ...
