Water Temperature Sensor Inspection
• Remove   the water temperature sensor (see Water Tem-
  perature Sensor Removal/Installation in the Fuel System
    (DFI) chapter).
•   Suspend the sensor [A] in a container of coolant so that
    the threaded portion is submerged.
•   Suspend an accurate thermometer [B] with temperature
    sensing portions [C] located in almost the same depth.
                              NOTE
    ○The sensor and thermometer must not touch the con-
     tainer side or bottom.

• Place   the container over a source of heat and gradu-
  ally raise the temperature of the coolant while stirring the
    coolant gently.
•   Using a digital meter, measure the internal resistance of
    the sensor.
    If the digital meter does not show the specified values,
    replace the sensor.
Water Temperature Sensor Resistance
          Temperature                 Resistance (kΩ)
          –20°C (–4°F)                  *18.80 ±2.37
           0°C (32°F)                  *(about 6.544)
          40°C (104°F)                  1.136 ±0.095
         100°C (212°F)                0.1553 ±0.0070
     *: Reference Information
Oxygen Sensor Removal
                          NOTICE
    Never drop the sensor especially on a hard surface.
    Such a shock to the sensor can damage it.

                          NOTICE
    Do not pull strongly, twist, or bend the oxygen sen-
    sor lead. This may cause the wiring open.

• Clear the oxygen sensor lead from the clamp [A].
• Disconnect  the oxygen sensor lead connector [B].

• Remove:
   Right Lower Fairing (see Lower Fairing Removal in the
     Frame chapter)
•   Clear the oxygen sensor lead from the clamp [A].
•   Remove the oxygen sensor [B].
