Kawasaki Ninja Service Manual: Exhaust Butterfly Valve Actuator Sensor Input Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Exhaust Butterfly Valve Actuator Sensor (Service Code 34) / Exhaust Butterfly Valve Actuator Sensor Input Voltage Inspection

NOTE

Be sure the battery is fully charged.

Turn the ignition switch to OFF.
Remove the front seat (see Front Seat Removal in the Frame chapter).
Remove the screws [A] and the exhaust butterfly valve actuator temporarily with the cables installed.

Exhaust Butterfly Valve Actuator Sensor Input Voltage Inspection

Disconnect the exhaust butterfly valve actuator sensor lead connector (3 pins connector) and connect the harness adapter [A] between these connector.

Special Tool - Throttle Sensor Setting Adapter #1: 57001 -1400

Connect a digital meter to the harness adapter leads.

Exhaust Butterfly Valve Actuator Sensor Input Voltage Connections to Adapter: Digital Meter (+) → Y/W (actuator W) lead Digital Meter (−) → BK/BL (actuator BK) lead

Exhaust Butterfly Valve Actuator Sensor Input Voltage Inspection

Measure the input voltage with the engine stopped and with the connector joined.
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 output voltage (see Exhaust Butterfly Valve Actuator Sensor Output Voltage Inspection).

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

Disconnect the ECU and sensor connectors.

Wiring Inspection ECU Connector [A] ←→ Exhaust Butterfly Valve Actuator 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).
