P0339code definition

P0339代码表明该汽车的计算机已从曲​​轴位置传感器中检测到一个超过汽车制造商设置的最大变化的电压信号。

P0339代码意味着什么

The P0339 code means that the car’s computer has detected a problem with the crankshaft position sensor A circuit. In this instance, it has detected a voltage reading that is higher than the maximum set by the manufacturer. Usually, the maximum allowable difference is 10% (between the actual reading and the manufacturer’s setting). Three instances are typically required to trigger the Check Engine light, but the pending code should be stored in the computer.

What causes the P0339 code?

A number of potential causes may lead to the P0339 code being set in the car’s computer, including the following:

  • 受损的曲轴位置传感器
  • Damage to the sensor’s connectors
  • 损坏传感器线束
  • Broken reluctor rings or missing teeth
  • Damage caused by a broken timing belt wrapping around the sensor system
  • Failed PCM (rare)

P0339代码的症状是什么?

P0339代码的症状可能取决于原因,但包括以下原因:

  • No noticeable symptoms
  • 检查引擎灯
  • 燃油经济性降低
  • 发动机性能降低
  • Rough idling
  • Engine misfire
  • 粗糙的加速度
  • 没有开始

机械师如何诊断P0339代码?

诊断P0339代码首先将OBD-II扫描仪连接到汽车的通信端口。机械师将读取存储的代码或代码,然后清除它们。然后,将需要进行测试驱动器(如果可能的话),以验证代码重置该代码。

接下来,机械师应检查曲轴位置传感器的线束和连接器。通常,问题的原因实际上是由于接触机油而导致的连接线束或连接腐蚀的恶化,这可以通过布线盖进食。如果发现损坏或发现了松动的连接,则必须更换或修复。

If the problem persists, the mechanic will need to test the crankshaft position sensor for operation. This may require removing the sensor from the vehicle to be tested correctly.

诊断P0339代码时的常见错误

Perhaps the most common mistake made when diagnosing the P0339 code is assuming that the problem is the crankshaft position sensor itself and not performing a complete diagnosis. One of the most common reasons for the P0339 code is actually damage to the wiring harness due to exposure to engine oil.

P0339代码有多严重?

P0339代码实际上是非常严重的,即使您没有遇到任何可驾驶性问题。如果问题是由于对线束或宽松连接的损坏引起的,情况只会增加严重性,可能会使您在不开始的情况下陷入困境。立即诊断出问题。

哪些维修可以修复P0339代码?

Repairs needed to fix the P0339 code vary depending on the underlying cause, but can include the following:

  • 修理或更换损坏的接线
  • 修复松散的连接
  • 修复负责接线退化的机油泄漏
  • 取代失败曲轴位置传感器
  • Replacing broken reluctor rings

有关P0339代码的其他评论

因为有多种原因,而失败的传感器并不总是根本的问题,因此对于机械师进行了深入的检查和对问题的诊断至关重要。万博亚洲客户端这将减少进行昂贵维修的机会,只是发现它没有解决这种情况的实际原因。
