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).
