涡轮/超级充电器增强控制电磁阀电路高
该代码具有由制造商提供的各种定义。该代码意味着ECU(发动机控制单元)已检测到涡轮增压器或增压器增强控制电磁阀电路的范围或异常读数。该代码与电路A作为Boost螺线管系统电路的区域有关,而不是特定的故障或组件。
真空系统在进气歧管上泄漏或增强控制
空气清洁剂
垃圾门被卡住了
排气歧管和涡轮增压器法兰之间的连接松动或不良垫圈
A restrictive connection between the turbocharger and the air intake connection
A bad boost pressure sensor
Shorted or open wiring in the boost sensor circuit
Loose, corroded, or disconnected electrical connectors in the boost sensor 5-volt reference circuit
Damaged turbo charger (usually caused by internal oil leaks and oil supply problems which can lead to bearing failure and blade damage)
Low or no boost
加速过程中失电的损失。
一旦ECM检测到螺线管电路高电流状况(表示开路),请检查发动机的光照明
如果P0048代码返回,则应该遵循此测试程序:
检查涡轮/超级充电器系统,密切注意螺线管阀和垃圾门(可能是不起作用的或卡住的)
检查升压传感器和相关接线上的接线是否有松动的连接,损坏的接线或故障传感器
检查操作过程中的升压和驾驶的正常范围为9至14 psi压力(确保压力不是不稳定或太高)
检查涡轮充电器是否有损坏的刀片,摇摆轴旋转,磨损轴承,漏油升级到涡轮增压侧以及正确的控制阀或废闸门操作
Do not replace any component, assuming it is bad, without carefully inspecting the system. Be sure to flush all debris and obstructions from the turbocharger oiling system that can lead to repeated turbo failure related to the bearings on the turbocharger shaft. Replacing the turbocharger without complete testing of the by-pass valve or waste gate function and electrical circuitry is also the cause of common misdiagnosis.
This code is very serious and is usually preceded by the engine warning light coming on. It should be diagnosed as soon as possible to prevent engine internal damage or turbocharger failure. Minimize your driving until the problem can be repaired. If the vehicle operates very poorly, do not drive it further.
The vehicle can run roughly or erratically, backfire, have rich or lean fuel consumption problems, and operate in over or under boost conditions.
通常,如果发动机警告灯在启动时立即亮起,则可以重置OBDII系统,并且车辆将正常运行。
P0048代码可能非常混乱,意味着提升太高,或者对ECU的输出电压太高。只需通过检查增强压力是否处于范围并顺利运行,将其作为原因消除。负载的条件是这种情况发生的情况。增强压力传感器对于控制燃料数量的燃料管理系统非常重要。
一段年龄和英里之后,传感器疲劳并开始逐渐读取范围,通常需要更换。万博亚洲客户端力学通常具有处理如此多的车辆的经验,以至于他们可以感觉到哪些组件的失败可能性更高。
许多行驶里程超过100,000的车辆都有瞬时的传感器问题,通常在启动或长时间的驱动火车上发生压力。如果发动机警告灯亮起并且车辆似乎正常运行,则可以使用扫描仪重置OBD-II系统,并且问题可能不会重新出现。这就是为什么在进行任何维修之前验证故障并重置故障的原因。
