Ford P0119 OBD-II Trouble Code Definition:
P0119 Engine Coolant Temperature Circuit Intermittent
P0119 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0119
Engine Coolant Temperature Circuit Intermittent
What does the code mean? OBD-ii Code P0119 definition:
The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.

Symptoms Sumptoms of OBD code P0119
– Engine Light ON (or Service Engine Soon Warning Light)
– Engine Light ON (or Service Engine Soon Warning Light)
Causes Causes of the OBD-II code P0119
– Low engine coolant level – Engine Coolant Temperature (ECT) sensor harness is open or shorted – Engine Coolant Temperature (ECT) sensor electrical circuit poor connection – Faulty Engine Coolant Temperature (ECT) sensor – Faulty engine coolant thermostat The Error code is generally activated on detection of the following conditions: The Engine Control Module (ECM) detected an erratic signal from the ngine Coolant Temperature (ECT) sensor during the system monitor test
