MID 036 - CID 0273 - FMI 00 Turbo Outlet Pressure above normal

Usage:

785C 1HW
产生此代码的情况:

电子控制模块(ECM)检测到在以下一种情况下,涡轮增压器压气机出口的绝对压力大于 200 千帕 (29 磅/平方英寸):

  • 发动机转速低于低怠速 + 50 转/分的情况达五秒钟。

  • 发动机转速高于低怠速且齿条处于最小值位置的情况达五秒钟。

ECM 已通电三秒钟。 以下诊断代码均未处于当前状态:

  • 262-03

  • 262-04

  • 273-03

  • 273-04

  • 273-13

系统响应:

记录该代码。 ECM 将涡轮增压器压气机出口压力标记为无效数据,并采用了默认值 0 千帕 (0 磅/平方英寸)。

测试步骤 1. 进行以下的诊断步骤: 发动机传感器断路/短路测试

结果:

  • 正常 - 停止

  • 已修复,正常。 - 停止
