路虎极光车辆故障码提示燃油压力过低
我有更好的答案
路虎的盲点是通过后杠两侧的雷达进行检测的,首先确认你近期是否有拆装过车辆的后杠, 是否拆过两侧的车门内饰板或贴膜,如果都没有的话,还得去4S店里读一下故障码,了解一下具体的原因。

GENERAL DESCRIPTION
The AD5543/AD5553 are precision 16-/14-bit, low power,current output, small form factor digital-to-analog converters.They are designed to operate from a single 5 V supply with a±10 V multiplying reference.
The applied external reference VREF
determines the full-scaleoutput current. An internal feedback resistor (RFB ) facilitates theR-2R and temperature tracking for voltage conversion whencombined with an external op amp.
A serial-data interface offers high speed, 3-wire microcontrollercompatible inputs using serial data in (SDI), clock (CLK), andchip select (CS ).
The AD5543/AD5553 are packaged in ultracompact(3 mm ? 4.7 mm) MSOP-8 and SOIC-8 packages.
