结构：半导体压敏电阻式压力传感器

功用：计算空气量，用来控制空燃比和负温度细数的热敏电阻，从而进一步控制燃油喷射量， 增压压力传感器用于测量进气歧管内的压力。发动机的进气量是由进气压力和发动机转速决定的。博世LDF6T型的传感器集成立压力传感器和温度传感器。

2、怎样判定进气量不足“看数据”一般来说六缸机进气量空车加油为1200Hpa=120Kpa 爬坡或者重车行驶时为2600Hpa=260Kpa左右进气压力传感器是ECU计算喷油量大小的重要依据信号异常：高电压值信号，可使ECU认为混合比加大喷油量，产动机无力冒黑烟，当超过时ECU突然断电停油。低电压值信号可使ECU减少喷油量发动机无力。

机油压力温度传感器

结构：半导体压敏电阻式压力传感器及负温度细数的热敏电阻

功用:用于向发动机控制单元提供发动机的机油温度，是在寒冷气温状态下。机油压力传感器安装在机油泵之后，用于测量机油压力并将这个信号传给电控单元（ECU）。

共轨压力传感器

结构：压阻式高压传感器，频率在1KHz，工作轨压： 1600bar
