Diagnostic Trouble Code (DTC) P0125 indicates the CHT sensor has not achieved the required temperature level to enter closed loop operating conditions within a specified amount of time after starting engine. This DTC will light the MIL.
Possible causes:

Insufficient warm up time.
Leaky or stuck open thermostat.
Low engine coolant level.
Malfunctioning CHT sensor.

No, I specifically read the REST of the relevant section of the WSM in addition to the section you quoted.

Dig deeper. Start by reading the entire diagnostic chain.
