问：在像O2一样维修时，您提供零件吗？

是的，当然，任何需要或所需的维修零件都可以成为任何维修订单的一部分，因此您不必经历研究和采购维修零件的时间和麻烦。我看到您正在询问更换氧气传感器。这些传感器最终确实磨损并且失败了，但是您只想确保只有用权威的诊断来证明传感器故障的权威诊断。您不想更换零件，只是因为这种替换无法解决您遇到的问题而感到失望。Just as for instance, if your check engine light came on, a Code was set and read, and that Code "included" O2 sensors as one potential fault, and the person reading the code then said "why don’t you try replacing the oxygen sensors", that would not be a good (or least cost) approach to resolving the problem. Parts should ONLY be replaced if they are scheduled for replacement (spark plugs are an example), are obviously broken (based on visual exam, simple tests), or test defective. The only way to condemn an oxygen sensor is to test it on a scope. If you already have a conclusive diagnostic, then you have already gone through the right steps and replacement of the sensors on a mobile basis with YourMechanic will save you money. If you want a diagnostic of the check engine light, relative to the O2 sensors, request a检查引擎灯诊断。如果您只想直接更换传感器，请要求的服务是O2传感器更换。请随时进行跟进，或与响应的认证机械师进一步讨论，他们来到您的位置，以便您可以充分了解并为您做出最佳决定。
