Diagnostic Trouble Code (DTC): P0436

P0436代码定义

TheP0436代码表示发动机库2的催化剂元素的运行效率不如应有的。

What the P0436 code means

In order to measure the efficiency of each catalyst in each converter, the PCM gathers data from a variety of sensors, particularly the upstream and downstream oxygen sensors. The upstream sensor reading fluctuates with the fuel conditions, while the downstream sensor reading stays fairly steady. If at any time, the readings from the sensors are too similar for engine bank 2, or do not fall within the manufacturer’s parameters, the P0436 code will be stored.

是什么原因导致P0436代码?

P0436代码的最常见原因是故障的催化转换器。其他原因可能包括:

  • 温度传感器故障
  • 不良氧气传感器
  • 打开或缩短温度传感器线束
  • 温度传感器电路中的电气连接不良

However, these causes are rare. Under the umbrella of “faulty catalytic converter”, there are several underlying causes that could be ultimately to blame. These include:

  • 使用不正确的燃料
  • 被污染的油
  • Faulty spark timing
  • 泄漏排气歧管
  • 冷却液温度传感器故障
  • Faulty fuel injection component
  • 泄漏管道
  • Leaking flex hose
  • Faulty mass air flow sensor
  • 歧管空气压力传感器故障
  • 压力调节器故障

P0436代码的症状是什么?

在许多情况下,车主可能观察到的唯一症状是检查引擎灯的照明。但是,如果任何转换器组件都融化或损坏,则发动机性能也可能会下降,或者在加速过程中嘶嘶声。在某些情况下,车辆可能根本无法启动。

How does a mechanic diagnose the P0436 code?

用OBD-II扫描仪验证代码后,机械师应对所有电气组件进行目视检查,特别是寻找腐蚀或松动的元素,以及用于泄漏的排气系统。如果任何一个区域都存在问题,则应修复此问题,并应清除代码并进行重新测试。

如果在这两个诊断过程之后,代码返回,则很可能是催化转换器不好。机械师应一次继续尝试进行一次维修,清除代码并进行重新测试,以确保他们查明问题。此过程将确保没有进行不必要的维修。

诊断P0436代码时的常见错误

In most cases, the biggest issue that technicians report is a previously repaired converter that did not have the underlying cause addressed. Without addressing the cause of the faulty converter, a new converter will likely fail again in a short time.

下一个最常见的问题是错误地指责氧气传感器。由于可以与P0436代码同时存在氧气代码,因此机械师可以立即替换该部分。万博亚洲客户端但是,应在更换之前对氧气传感器进行适当的操作进行测试,因为通常不责怪它。

P0436代码有多严重?

If the P0436 code is being detected, the vehicle should still be drivable. Unless there are serious breakages or melted parts within the converter components, this is not an emergency issue. It may, however, affect the vehicle’s ability to pass an emissions test, and it should be repaired when time allows.

What repairs can fix the P0436 code?

在大多数情况下,修复故障的催化转换器并修复导致故障的根本问题,将修复P0436代码。其他维修可能包括:

  • 更换故障温度传感器
  • 修理开放或短暂的温度传感器线束
  • Repairing a poor electrical connection within the temperature sensor circuit
