When I connect my code reader to a vehicle and find a stored P0119, I know that the powertrain control module (PCM) has detected an intermittent signal from the engine coolant temperature (ECT) sensor. The PCM monitors ECT using a reference circuit (typically five-volts) that is completed by the ECT sensor.

2022年5月20日 · 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 …

2024年12月16日 · The P0119 code is a diagnostic trouble code (DTC) that indicates an issue with the Engine Coolant Temperature (ECT) Sensor 1 circuit. This sensor plays a crucial role in monitoring the temperature of the engine coolant, helping to …

2024年7月19日 · The P0119 is a trouble code that indicates a possible issue with the vehicle’s engine coolant temperature sensor or its circuit. What are the causes and symptoms of this trouble code and how should you address it?

The OBD-II code P0119 indicates that there is a problem with the engine coolant temperature sensor 1 circuit that is failing intermittently or erratically. The engine control module (ECM) is responsible for interpreting the voltage signal sent by the ECT sensor.

2024年11月5日 · P0119故障代码表示发动机冷却液温度（ECT）传感器信号间歇性或不稳定。 虽然这通常不会立即造成威胁，但带着这个问题行驶可能会导致燃油经济性差、怠速不稳，以及由于燃油混合物和点火时机不正确而造成潜在的发动机损坏。

When diagnosing OBD-II code P0119, identifying common causes such as a faulty Engine Coolant Temperature (ECT) sensor, wiring issues, or circuit malfunctions is essential. Regular sensor maintenance is key in preventing engine performance problems associated with erratic ECT sensor readings.

2016年1月11日 · P0119 will set if there is an open, short to ground or an intermittent circuit condition between the engine computer (ECM/PCM) and ECT sensor. What are the common causes of code P0119? Low engine coolant level Defective engine coolant thermostat ECT sensor harness is open or shorted ECT sensor electrical circuit poor connection

2024年7月9日 · What is P0119 Fault-Error Code? P0119 Fault-Error Code indicates a problem with the Engine Coolant Temperature (ECT) sensor circuit and specifically indicates an intermittent electrical connection or signal from the ECT sensor to the Engine Control Module (ECM) or Engine Control Unit (ECU).

發動機冷卻液溫度（ECT）感測器通過熱敏電阻的原理將發動機冷卻液的溫度以電信號的形式傳輸給電子控制單元（ECU），作為修正噴油和點火的一個依據。 如果ECU檢測到發動機在運行 …
