诊断并修复斯巴鲁P2762

斯巴鲁P2762是一个相当常见的故障代码,其定义为:P2762变矩器锁止电磁阀电路(低)。 现在,在你做任何愚蠢的事情之前,比如跳到你需要一个新的变矩器或一个新的锁止电磁阀的结论,让我们来看看这里发生了什么。 在许多情况下,斯巴鲁P2762还伴随着P0700,C0057和C0045故障代码。 就斯巴鲁P2762故障代码的定义而言,其定义为:P2762变矩器锁止电磁阀电路(低)。作为身体症状,您可能会感到减速时熄火和驾驶时抽搐。

什么是变矩器锁止?

理解液力变矩器工作原理的最佳方式是将两个台扇对准对方。 打开一个风扇,风速将使第二个风扇旋转。 液力变矩器也包含两个类似风扇的结构。 一个与液力变矩器壳体相连,壳体通过螺栓固定在发动机飞轮上(称为 "柔性盘")。 第二个风扇与输入轴相连。风扇不是向另一个风扇吹气,而是向另一个风扇吹气。 在手动变速器中,液力变矩器取代了飞轮、离合器片和压盘。 液力变矩器允许发动机在怠速状态下继续运转,而不会导致发动机熄火。 换句话说,在怠速转速下,变速器油只是在两个风扇叶片之间 "搅动"。

驾驶时,液力变矩器的作用就像普通离合器一样,将发动机的转速传递到变速器输入轴。 但这种设置存在一个问题,即能量损失。 在典型的离合器系统中,发动机的一转等于变速器输入轴的一转。 但由于液力变矩器喷射的是变速器油,因此在此过程中会损失一些能量。 为了解决这个问题为了减少能量损失,汽车制造商对变矩器进行了改装,在变矩器内部安装了一个离合器装置,通过机械方式将两个风扇锁定在一起。 这样就能以1:1的比例将动力从发动机传递到变速器。

锁止电磁阀接收变速器控制模块(TCM计算机)发出的 "占空比 "指令,打开和关闭油道,允许或禁止加压变速器油进入离合器机构。 占空比范围从0%油流到100%油流,用于离合器完全接合。

斯巴鲁P2762故障代码是什么意思?

斯巴鲁公布了一份检查清单,其中列出了需要测量的项目,以确定代码设定的原因,范围包括电磁阀短路、内部电阻过高或电磁阀接地不良。 以下是斯巴鲁规定的测试项目:

断开TCM和变速器的电气连接器,测量TCM连接器腔体B54 #26底盘接地之间的电阻。 电阻至少应为1Ω。 如果读数低于1Ω,说明线束短路。

2)接下来检查变速器连接器T4 #2和变速器本体之间的电阻。 发动机冷车时电阻应为13Ω。

3) 检查变速器内部的线束。

在某些情况下,修复方法是更换线束。

电磁阀损坏是P2762最常见的原因。

不幸的是,锁止电磁阀内置于变速器阀体中。 电磁阀不能作为单独部件提供。 因此,您必须更换整个阀体。 斯巴鲁技术人员发现,真正的问题往往是由变速器阀体损坏引起的。 如果您遇到 P2762 故障代码,在更换任何变速器部件之前,请咨询斯巴鲁专家。
