color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; text-align: justify; line-height: 1; outline: 0px !important;">故障码为：<p style="box-sizing: border-box; margin-top: 0pt; margin-bottom: 0pt; color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; text-align: justify; line-height: 1; text-indent: 24pt; outline: 0px !important;">1.电子气门控制伺服马达，识别到过流。<p style="box-sizing: border-box; margin-top: 0pt; margin-bottom: 0pt; color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; text-align: justify; line-height: 1; text-indent: 24pt; outline: 0px !important;">2.电脑版DME内部故障.<p style="box-sizing: border-box; margin-top: 0pt; margin-bottom: 0pt; color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; text-align: justify; line-height: 1; text-indent: 24pt; outline: 0px !important;">3.电子气门伺服马达：电源对地短路、<p style="box-sizing: border-box; margin-top: 0pt; margin-bottom: 0pt; color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; line-height: 1; text-indent: 24pt; outline: 0px !important;">我们首先要了解宝马这款车的独特构造，通过一个伺服电机控制偏心轴，无级改变曲轴和每个气门之间的控制杆相对曲轴位置，并根据控制杆位置无级调节，凸轮轴提升被转化为一个变化的角度，而无论多少，凸轮轴提升都是有控制杆的位置决定的，由于凸轮轴提升的变化，气门的开启时间也会随之相应变化，从而取代过去的节气门，对发动机的动力加以控制。使用电子气门伺服电机控制气门的升程，是宝马的特色。<img decoding="async" width="551" height="287" class="wp-image-308 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305154558863-20250305154558305-Picture-2-551w287h.png" alt="C:\Users\ADMINI~1\AppData\Local\Temp\WeChat Files\81d38a63e350e20872907c9e1e99f96.png" imgbox-index="2" style="box-sizing: border-box;

margin-top: 0pt; margin-bottom: 0pt; color: rgb(78, 83, 88); font-family: "Helvetica Neue", Helvetica, Arial, sans-serif; font-size: 16px; text-align: justify; line-height: 1; outline: 0px !important;"><img alt="图片-2011款宝马5系冷启动困难案例-蛙趣网" decoding="async" width="553" height="233" class="wp-image-311 size-full" src="https://wapq.cn/wp-content/uploads/2025/03/20250305154603156-20250305154603103-image6-553w233h.png" imgbox-index="5" style="box-sizing: border-box;
