SCR系统尿素回流管堵塞故障现象：
①启动后，OBD故障灯常亮；②发动机限扭、没劲；③故障码：P0207（SCR系统尿素回流管堵塞故障）；④不消耗尿素。原因分析：尿素回流管中杂物堵塞，导致系统无喷射尿素，排放**标，发动机限扭，系统报警。解决措施：检查尿素回流管(尿素泵到尿素箱间的尿素管)。

10、尿素回流加热管路插接件端子插歪现象：OKT
①启动后，OBD故障灯常亮；②故障码：P0287（尿素回流管路加热继电器负载端与电源之间的线路发生开路或对地短路故障）。原因分析：拔下尿素加热回流管接插件，发现端子。解决措施：修复端子，重新插好接插件。

11、尿素压力管路开路故障现象：
①启动后，OBD故障灯常亮；②故障码：P028E（尿素压力管路加热继电器负载端与电源之间的线路发生开路或对地短路故障 ）；③冬季发动机可能限扭、没劲。原因分析：尿素泵压力管加热丝断路，导致冬季不能正常给尿素加热，同时系统报警。解决措施：检查尿素泵压力管（从尿素泵到尿素喷嘴间的尿素管路）。
