Q: Engine code P0430 and losing oil

Diagnostic Trouble Code P0430意味着ECU检测到催化转化器的阈值性能低于阈值。ECU密切监视催化转换器，当检测到低性能阈值时，检查引擎灯将显示在仪表板上。尽管催化转化器本身可能是错误的，但必须首先排除许多其他可能导致低效率的原因，包括发动机失灵，燃油喷射器泄漏，发动机机械损坏，氧气传感器，输出范围值和范围值不超出范围值以及排气泄漏。

Oil leaks can be external or internal. Internal oil leaks often occur at the valve stem oil seals and/or the valve guides as well as at worn piston rings. External leaks could occur at spark plug tube seals, the PCV grommet, oil pressure sensor, crankshaft seals, oil pan seal, head gasket, and so forth. Oil leaks should be repaired because leaking oil can damage external engine components such as rubber motor mounts. If you want the source of all oil leaks identified and the repair estimated, simply request an机油泄漏诊断. If you have further questions or concerns, do not hesitate to re-contact万博体育入口.
