Oxygen Sensor Heater Removal/Installation

The oxygen sensor heater is built in the oxygen sensor.

So, the heater itself can not be removed. Remove the oxygen sensor (see Oxygen Sensor Removal (Equipped Models) in the Electrical System chapter).

Oxygen Sensor Heater Resistance Inspection

  • Turn the ignition switch OFF.
  • Remove the right lower fairing (see Lower Fairing Removal in the Frame chapter).
  • Open the clamp [A], and pull out the oxygen sensor lead connector [B].
  • Disconnect the oxygen sensor lead connector.

Oxygen Sensor Heater (Service Code 67, Equipped Models)

  • Connect a digital meter [A] to the oxygen sensor lead connector [B].
  • Measure the oxygen sensor heater resistance.

Oxygen Sensor Heaters Resistance
 Connections: BK lead [C] ←→ BK lead [D]
 Standard: 11.7 - 14.5 Ω at 20º C (68ºF)

If the reading is out of the standard, replace the sensor.

If the reading is within the standard, check the power source voltage (see Oxygen Sensor Heater Power Source Voltage Inspection).

Oxygen Sensor Heater Power Source Voltage Inspection

NOTE

  • Be sure the battery is fully charged.

 

  • Turn the ignition switch OFF.
  • Disconnect the oxygen sensor lead connector and connect the harness adapter [A] between these connectors.

Special Tool - Measuring Adapter: 57001-1700

Oxygen Sensor Heater (Service Code 67, Equipped Models)

  • Connect a digital meter [D] to the harness adapter lead.

Oxygen Sensor Power Source Voltage
 Connections to Adapter:
  Digital Meter (+) → Y (sensor BK) lead
  Digital Meter (-) → Battery (-) terminal

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

Power Source Voltage
 Standard: Battery Voltage

  • Turn the ignition switch OFF.

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

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

    FI Fuse 15 A (see Fuse Inspection in the Electrical System chapter) Power Source Wiring (see wiring diagram in this section)

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

  • Disconnect the ECU and sensor connectors.

Wiring Inspection
 ECU Connector [A] ←→
  Oxygen Sensor Connector [B]
  R lead (ECU terminal 9) [C]

If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).

    Oxygen Sensor Removal/Installation Refer to the Oxygen Sensor Removal/Installation in the Electrical System chapter. Oxygen Sensor Inspection Warm up the engine thoroughly until the radiator fan starts. Turn the ignition switch OFF. Remove the right lower fairing (see Lower Fairing Removal in the Frame chapter). Open the clamp [A], and pull out the oxygen sensor lead connector [B]. Disconnect the oxygen sensor lead connector (4 pins connector) and connect the harness adapter [A] between these connectors.
