Engine Coolant Temperature; Indicator/Ect Sensor - Honda CB 600F Hornet 2007 Shop Manual

Connect the peak voltage adaptor or Imrie diagnos­
tic tester probe to the combination meter 20P con­
nector Yellow/green
terminals.
TOOLS:
Imrie diagnostic tester (model 625) or
Peak voltage adaptor
with commercially available digital multimedia
(impedance 10 Mn/OCV minimum)
CONNECTION:
Start the engine and measure the tachometer input
peak voltage.
PEAK VOLTAGE: 10.5 V minimum
If the peak voltage is normal, replace the combina­
tion meter circuit board (page 20-10).
If the measured value is below 10.5 V, replace the
ECM (page 5-96).
If the value is O V, check for continuity between the
combination meter 20P connector and ECM 33P
(Light gray) connector Yellow/green terminals.
TOOL:
Test probe
If there is no continuity, check the wire harness for
an open circuit.
If there is continuity, replace the ECM (page 5-96).

coolant temperature, inspect the following.
Disconnect the ECT sensor 3P (Black) connector
from the sensor.
Ground the Green/blue wire terminal of the ECT
sensor 3P connector wire harness side with a
