The engine coolant temperature is monitored by the Powertrain Control Module (PCM) when the engine is running. This ensures that it does not reach an unsafe level and can cause damage to the vehicle. If the PCM senses that the engine coolant temperature has not reached 176°F (80°C) after 20 minutes of driving, a Diagnostic Trouble Code (DTC) will be stored in its memory. This indicates that further investigation may be necessary to identify any potential issues with the cooling system or other related components.
