Description

OBD-II Trouble Code Description for P0119 Dodge

Engine Coolant Temperature Circuit Intermittent

What does this mean?

OBD2 Code P0119 Dodge 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

Possible sumptoms of OBD code P0119 Dodge
– Engine Light ON (or Service Engine Soon Warning Light)

Causes

Possible causes of OBD code P0119 Dodge
– 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

Possible Solutions

Replace Coolant, or top up Check with Live data reading from ECT sensor Replace Coolant Temp Sensor
