2016年1月14日 · A dead battery or worn starter may crank the engine over slowly, or not at all. Since the ECM sees a starter signal but a weak or non-existent CKP signal, it may set a DTC P0337, even if there is no problem with the sensor or circuit.

When I have diagnosed a stored code P0337 (in the past) it was because the powertrain control module (PCM) had detected a low input voltage signal from the crankshaft position (CKP) sensor circuit. CKP sensors are responsible for monitoring engine speed (RPM) and crankshaft position.

The P0337 error code may appear for several reasons, including: Faulty Crankshaft Position Sensor: A crankshaft position sensor that is broken or not working properly may provide a low-voltage signal. Wiring Issues: Damaged or corroded wiring in the crankshaft position sensor circuit can result in poor electrical connections.

曲轴位置（CKP）传感器 (也叫上止点传感器），其作用是检测上止点（TDC）信号、曲轴转角信号和发动机转速信号，并将其输入计算机，从而使计算机能按气缸的点火顺序发出最佳点火时刻指令。 如果电子控制单元（ECU） 检测 到曲轴传感器A电路电压低于校准的最低值，该 故障码 会出现。 1.此OBD故障码适用于所有汽车制造商故障码：P074D中文含义：不能挂5档英文含义：UnableToEngageGear... 1.此OBD故障码适用于所有汽车制造商故障码：P0738中文含义： …

2025年2月4日 · What does the P0337 code mean? The P0337 code indicates a problem with the Crankshaft Position Sensor A circuit. This sensor plays a crucial role in monitoring the position and speed of the crankshaft, which is vital for engine timing.

2017年6月24日 · P0337故障码，适用于所有汽车制造商，意思是曲轴位置（CKP）传感器A电路低(Crankshaft Position Sensor A Circuit Low)。 提示：快速查找故障码，可以关注“ 车主指南 ”公众号，回复故障代码，如：“ P0337 ”，即可获得对应故障码解释和解决方案。

p0337故障码详解与解决策略 在汽车世界里，故障码是诊断问题的钥匙，其中P0337故障码尤其引人注目。 它代表了曲轴位置（CKP）传感器A电路电压偏低，意味着车辆的发动机控制系统检测到了曲轴位置传感器的异常状态。

故障码：p0337详细介绍如下 ： 故障所属系统范围：点火系统. 适用车型：所有汽车制造商. 中文含义解释：曲轴位置传感器 -输入电压低. 英文含义：暂无. p0337故障码相关知识：

2024年4月10日 · Code Definition: P0337 indicates a Crankshaft Position Sensor A Circuit Low Input. Common Symptoms: Symptoms include engine misfires, rough idling, reduced fuel efficiency, and the Check Engine light turning on. Potential Causes: Causes range from faulty sensors and damaged wires to improper sensor alignment and ECM issues.

A P0337 code can be caused by either a dead starter motor or a bad battery. When the engine is turned on, the PCM waits to receive a signal from CKP. A weak CKP signal means that the engine doesn’t spin fast enough due either to a low or worn starter motor. You should make sure to fix the starter motor and battery issues immediately.
