Q: Car won't start after it gets warm.
我的车在变暖后不会启动。我得到了代码P0021，凸轮轴位置过高。
这些都是代码P0021的可能原因：
- 银行2凸轮轴传感器或银行2凸轮正时电磁阀有故障
- 连接器端子触点已损坏或腐蚀
- 电线线束 - 检查线束是否正确电压
- Open, short to ground or short to voltage
- Update control unit software - check for the latest control unit update
- Engine Control Module faulty
需要检查传感器连接器与凸轮正时电磁阀的连接器一起检查。进气凸轮轴时机在其默认位置完全提前，因此螺线管及其接线是该故障的主要嫌疑人。您可能需要寻求机械师的帮助，例如您的机械师，他们将拥有设备和专业知识来诊断您的设备和专业知识万博体育入口car not starting.
