Monitored & Set Conditions
Closed loop operation is monitored when engine is running and battery voltage is more than 10.4 volts. DTC will set in Powertrain Control Module (PCM) memory when PCM senses engine temperature does not increase more than 50°F in 10 minutes after engine is started. Two consecutive trips are required to set this DTC. Possible causes for DTC to set are: low coolant level, defective thermostat or defective Engine Coolant Temperature (ECT) sensor.
