代码是P0430，看起来跟进气系统有关系吧; 之前有冷车怠速不稳的情形，清洁以后也好多了


Fault Code Definition
The Bank 2 Catalytic Converter's emissions reducing efficiency has fallen below the minimum allowable threshold. This efficiency is tracked by a monitoring Oxygen Sensor that is mounted near the outlet of the Catalytic Converter.

Symptoms

    Check Engine Light will illuminate
    In many cases, no abnormal symptoms may be noticed
    In some cases, there may be a noticeable lack of engine power

Common Problems That Trigger the P0430 Code

    Defective Catalytic Converter
    Internal engine damage resulting in high oil consumption and/or a leaking Head Gasket has damaged the Catalytic Converter

Common Misdiagnoses

    Oxygen Sensor(s) are replaced when the real problem is a damaged Catalyst
    Catalyst is replaced when the real problem is internal engine damage, which is producing elevated emissions levels
    Catalyst is replaced when a misfiring engine is the real problem




【 在 TATRA (托托) 的大作中提到: 】
: 清洁空滤和MIL灭掉之间也许没有必然联系，也许是故障消失后正好就灭了。
: MAF如果不是很有经验最好别动，万一把热线搞断了就麻烦了。
