Yes To step 6 2 The observed data stream "coolant temperature", and
whether the engine temperature quite (numerical and
when the engine temperature). Note: if the display
value often is constant, that there may be circuit
breaker failure.

Yes Next step 3 Dial the connector for coolant temperature sensor
wire harness, electrical multimeter check sensor a#
and c# pins of value is commensurate with its
temperature (with specific reference to the relevant
part of the repair manual).
No Replace the sensor
Yes To step 6 4 Dial the connector for coolant temperature sensor
wire harness, using a multimeter to check the joint
line between the a#, c# pin is broken
No Next step
Yes Repair or replace the wire

Yes Diagnostic aid 6 Start the engine, idle running. To observe the
diagnostic instrument "coolant temperature" value
changes, the display values should be increased
along with the engine coolant temperature
