Kawasaki Ninja Service Manual: Oxygen Sensor Heater Power Source Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Oxygen Sensor Heater (Service Code 67, Equipped Models) / Oxygen Sensor Heater Power Source Voltage Inspection

NOTE

Be sure the battery is fully charged.

Oxygen Sensor Heater Power Source Voltage Inspection

Turn the ignition switch to OFF.
Remove the fuel tank (see Fuel Tank Removal in the Fuel System (DFI) chapter).
Disconnect the oxygen sensor lead connector and connect the measuring adapter [A] between these connectors as shown in the figure.

Main Harness [B] Oxygen Sensor [C]

Special Tool - Measuring Adapter: 57001-1700

Connect a digitalmeter [D] to the measuring adapter lead.

Oxygen Sensor Heater Power Source Voltage Connections to Adapter: Digital Meter (+) → R (main harness W/R) lead Digital Meter (–) → Frame Ground terminal

Oxygen Sensor Heater Power Source Voltage Inspection

Measure the power source voltage with the engine stopped and with the connector joined.
Turn the ignition switch to ON.

Power Source Voltage Standard: Battery Voltage

Turn the ignition switch to OFF.

If the reading is in specification, but the problem still exists, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

If the reading is out of the standard, check the following.

ECU Relay Fuse 15 A (see Fuse Inspection in the Electrical System chapter) Power Source Wiring (see Oxygen Sensor Circuit)

If the fuse and wiring are good, remove the ECU and check the wiring for continuity between harness connectors.

Special Tool - Hand Tester: 57001-1394

Disconnect the ECU and sensor connectors.

Wiring Continuity Inspection ECU Connector [A] ←→ Oxygen Sensor Connectors [B] R lead (ECU terminal 76) [C]

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).
