P242F OBD-II: 柴油微粒过滤器限制 - 积灰 OBD-II故障代码P242F是什么意思？
OBD-II代码动力总成控制模块（PCM）软件需要更新被定义为柴油微粒过滤器限制 - 积灰
柴油机排气液（DEF）用于帮助将残留的废气颗粒转化为无害气体。 为了燃烧这些颗粒，排气系统的温度需要升高。 向废气流中注入柴油机排气液（DEF）可使柴油机微粒过滤器（DPF）升温。 然后，该系统能够将有害的氮氧化物转化为氮、二氧化碳和水。添加了还原催化剂（SRC），以进一步减少排气中的氮氧化物。 发动机计算机（PCM）监控DPF前后的排气压力。 再生（燃烧掉捕获的颗粒）完成后，排气压力应降低。 如果没有降低，PCM认为DPF中存在限制。 代码P242F将设置。
有此故障代码的车辆应送至修理厂进行诊断。 查找修理厂
