我们的认证力学来了万博亚洲客户端
P0329是“敲击传感器1电路输入间歇性(银行1或单个传感器)”的诊断故障代码(DTC)。这可能是出于多种原因而发生的,并且机械师需要诊断在您的情况下触发此代码的具体原因。我们经过认证的移动机制可以来您的家庭或办公万博亚洲客户端室执行检查引擎灯诊断$ 114.99. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.0 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
Knock Sensor 1 Circuit Input Intermittent (Bank 1 or Single Sensor)
A knock sensor is used to optimize engine performance. It also helps protect the engine against potentially dangerous and power robbing engine knock. Trouble code P0329 indicates that the knock sensor detects an abnormal amount of pinging or vibration coming from the engine. The knock sensor will produce a voltage when there is excess knock, spark knock, vibration or engine pinging present. The knock sensor was implemented to help alert the driver of any potential internal engine issues as well as to help monitor the air-fuel ratio (AFR). The voltage signal sent by the knock sensor will tell the Engine Control Module (ECM) if a “knock” is present. If a such knock is present, the ECM will then adjust the air-fuel ratio by the advancement or retard of the timing.
敲击传感器是发动机的一种警报。就像防盗警报如果车身易于振动过多,则敲击传感器也会通过类似的方式参与。
敲击传感器被设计为发动机的应力信号。敲击传感器的内部是压电,这意味着它由晶体组成,如果经历机械应力,它将产生电力;敲击传感器是一种传感器,将机械能转换为电力。
Under normal conditions, a knock sensor will only produce less than one volt, though if a knock sensor experiences too much vibration, it will produce anywhere from 1.0 - 5.0 volts. When the knock sensor’s voltage output is beyond the range that the Engine Control Module expects as “normal”, a code P0329 may set.
使用数字万用表来测量敲击传感器的电压输出
轻轻敲击敲门传感器和发动机以验证电压增加 - 可以用锤子轻轻完成(在大多数敲门传感器上起作用)
使用数字万用表测试敲击传感器的电阻。电阻应等于制造商的规格。规格每辆车各不相同。您可能会通过网站找到车辆的规格prodemand, 或者问机械师
使用扫描工具检查冻结框架数据
Uses a scan tool to check the advance or retard of the ignition timing
Checks the fuel pressure
检查燃料的质量
检查火花塞的状况和相关的点火组件
这可能是相当严重的。这可能是对汽油不好或更昂贵(例如失败的发动机活塞戒指)等小的东西的警告。就像火警警报一样,通常造成的损坏量取决于警报的注意力速度。该代码的原因可能是财务财务量表的较小方面,但是由于各种可能性,请尽快对其进行检查是一个好主意。
通常,如果使用不正确的辛烷值,则将设置此代码。我们建议验证在尝试采购此问题时汽油是车辆的合适辛烷值。另外,请确保汽油“清晰”并且没有碎屑。
