C11, C13 and C15 On-highway Engines Caterpillar


0105-04 Intake Manifold Air Temperature voltage low (38)

Usage:

C15 BXS
产生此代码的情况:

发动机控制模块 (ECM) 检测到以下情况:

  • 进气歧管温度传感器送来的信号电压低于 0.2 VDC 超过八秒。

  • ECM 至少已通电两秒钟。

  • 168-01 ECM 蓄电池电量不足没有激活。

  • 105-00 进气歧管空气温度过高报警(进气歧管空气温度过高报警)没有激活。

  • 105-11 进气歧管空气温度极高(进气歧管空气温度极高)没有激活。

注: 进气歧管空气温度高于 140 °C (285 °F)有可能会激活此代码。

系统响应:

ECM 将记录诊断代码并触发快照。 当该诊断代码变为激活状态 10 小时后,检查发动机指示灯点亮。 ECM 将 40 (C)104 °F 默认为进气歧管空气温度。 如果增压压力高于 70 kPa (10 psi),ECM 将会打开冷却风扇。

测试步骤 1. 进行以下的诊断步骤: 发动机温度传感器开路或短路 - 测试

结果:

  • 正常 - 停止
