绝对压力 - 绝对压力是表压力加上当地大气压力。
表压力 - 表压力是绝对压力减去当地大气压力。
进气歧管压力传感器测量进气歧管空气绝对压力。 电子点火系统的控制模块(EIS控制模块)和电子控制模块(ECM)使用来自进气歧管有利传感器的信息来计算发动机负荷。
为确认进气歧管压力传感器准确与否，在发动机停机时，使用卡特彼勒电子技师(Cat ET)或数字诊断工具(DDT)来查读进气歧管空气压力。 正确的压力将是外界大气压力。

空气进气歧管的螺塞 | |
从空气进气歧管上拆下一个螺塞。 从孔口到 1U-5470 发动机压力表组件 的一个压力表之间连接一根管。 发动机带载运转。 使用Cat ET或DDT来查读进气歧管空气压力。 读取 1U-5470 发动机压力表组件 的表压力并加上当地大气压力。 将计算结果与Cat ET或DDT的读数相比较。
