2022年3月16日 · What Does the P0115 Code Mean? Diagnostic trouble code (DTC) P0115 stands for “Engine Coolant Temperature Sensor Circuit.” This code sets when the powertrain control module (PCM) detects erratic or irrational input signals coming from the engine coolant temperature (ECT) sensor circuit.

2024年8月1日 · 在汽车世界里，故障码是车辆与驾驶员沟通的重要桥梁，其中P0115故障码尤为引人关注，它意味着“发动机冷却液温度（ECT）传感器1电路”存在问题。 面对这一代码，我们不仅需要理解其背后的技术细节，还需掌握有效的处理方法，确保行车安全与顺畅。 P0115故障码的出现，通常提示着发动机冷却液温度传感器1电路出现了问题。 这一传感器通过热敏电阻原理，将发动机冷却液的温度转化为电信号，传递给电子控制单元（ECU），作为调整喷油和点火的重要 …

A P0115 code indicates a malfunction in the Engine Coolant Temperature (ECT) circuit. This issue can lead to inaccurate readings of your engine’s temperature. When the ECT sensor fails, the engine control unit may not receive correct data about coolant temperature.

2025年2月2日 · What does the P0115 code mean? The P0115 code is a diagnostic trouble code (DTC) that indicates an issue with the Engine Coolant Temperature Sensor 1 Circuit. This sensor plays a vital role in monitoring the engine’s coolant temperature, providing crucial data to the vehicle’s engine control unit (ECU).

发动机冷却液温度（ECT）传感器通过热敏电阻的原理将发动机冷却液的温度以电信号的形式传输给电子控制单元（ECU），作为修正喷油和点火的一个依据。 如果ECU检测到发动机冷却液温度（ECT）传感器信号电压超出校准的正常范围，该故障码会出现。 本站提供的信息仅供参考, 如果您需要更多的资讯, 请询问您的工程师或4S店.

The P0115 OBD-II trouble code indicates a malfunction in the engine coolant temperature circuit. This code is triggered when the Engine Control Module (ECM) detects a voltage signal from the coolant temperature sensor that is outside the specified range. The coolant temperature sensor is responsible for monitoring the temperature of the engine ...

2024年10月29日 · p0115诊断故障码表示发动机冷却液温度（ect）传感器电路存在问题。 这是一个通用的OBD-II代码，适用于大多数品牌和型号的车辆。 如果出现此代码，您应该尽快诊断以防止潜在的发动机损坏，但大多数情况下，可以在短距离内安全驾驶，直到您找到技师。

Code P0115 is set when the Powertrain Control module sees erratic or irrational voltage signals from the coolant temperature circuit. P0115 Symptoms. Check Engine Light will illuminate; In many cases, no abnormal symptoms may be noticed; In some cases, the engine may be hard starting and/or get poor fuel economy; Common Problems That Trigger ...

2016年7月9日 · What Does Code P0115 Mean? OBD II fault code P0115 is defined as “Engine Coolant Temperature Circuit Malfunction”, and is set when the PCM (Powertrain Control Module) detects a circuit voltage value in the engine coolant temperature sensor that falls outside of a predetermined range.
