P0606 OBD-II：控制模块处理器 OBD-II故障代码P0606是什么意思？
OBD-II代码P0606被定义为PCM处理器故障。
这意味着什么？
PCM或动力传动控制模块在现代汽车中执行许多重要功能，例如管理燃油系统、点火系统、变速器、防抱死制动和牵引力控制系统。 PCM定期运行自我诊断功能，执行正常的数学计算，如果计算结果与预期不符，则设置P0606代码。

P0606 症状
- 发动机检查指示灯点亮
- ABS/牵引力控制指示灯可能点亮
- 车辆可能无法正常行驶和/或换档
- 燃油经济性降低
- 在某些情况下，可能会出现性能问题，如停车时熄火和/或类似失火的症状。
- 在特殊情况下，驾驶员未发现任何不利条件
触发P0606代码的常见问题
- PCM（动力传动控制模块）故障
- PCM接线/连接故障
- PCM接地电路故障
- PCM控制的输出设备有缺陷
- CAN 总线通信故障
常见误诊
- 根本原因是PCM故障的点火问题
- 根本原因是PCM故障的燃油喷射问题
排放的污染气体
- HCs（碳氢化合物）：未燃烧的原燃料液滴，有异味，影响呼吸，导致烟雾。
- CO（一氧化碳）：部分燃烧的燃料，是一种无味的致命有毒气体。
- NOX（氮氧化物）：在阳光照射下导致烟雾的两种成分之一。
P0606 车间和技术人员诊断理论
当动力总成计算机中设置代码P0606时，这意味着动力总成计算机或PCM的自检失败，并发现CPU（中央处理器）存在问题。 因此，在大多数情况下，处理器本身存在缺陷，需要更换PCM并重新编程。 但是，在更换PCM之前，请务必检查任何可能导致短路的输出设备。CPU 故障。
当诊断P0606代码时，重要的是记录任何其他代码和P0606冻结帧数据。 然后，应通过试车重复代码设置条件。 密切注意发动机负荷、节气门位置、转速和路速，因为P0606可能很难检测到。
