P0936代码定义

P0936故障代码指出了液压压力传感器中的间歇性电路误差。

P0936代码意味着什么

The P0936 code is a generic OBD-II trouble code that detects a problem with the hydraulic pressure sensor circuit. The purpose of the hydraulic pressure system is to provide power to help the automatic transmission shift gears. Each gear has a hydraulic circuit associated with it, and when the vehicle calls for an upshift or a downshift, the different hydraulic circuits will engage or disengage to make the shift happen. This is all controlled by the powertrain control module (PCM) and transmission control module (TCM), which calculate the proper shift strategy by accounting for various different engine factors and conditions. The PCM then monitors the hydraulic pressure by receiving data from the hydraulic pressure sensors. If the PCM receives an abnormal signal, or no signal at all from the hydraulic pressure sensors, then the P0936 trouble code may be stored.

What causes the P0936 code?

P0936故障代码几乎总是由电气组件受损。这可以包括爆炸的保险丝，腐蚀的电缆，短或敞开的电线或失地损失。该代码的其他潜在原因是有缺陷的液压传感器，PCM或TCM故障。

What are the symptoms of the P0936 code?

当检测到P0936故障代码时，检查引擎很快警告灯可能会在车辆的仪表板上照亮。传输问题通常是显而易见的，例如无法转移到某些齿轮（可能导致加速缓慢或发动机速度过高）和严格的转移。大多数车辆还会降低燃油效率。

机械师如何诊断P0936代码？

P0936代码将被诊断为标准的OBD-II故障代码扫描仪。训练有素的技术人员将使用扫描仪查看冻结框架数据并评估P0936代码。扫描仪还将用于检查是否存在任何其他故障代码，因为应始终按照其显示的顺序解决代码。然后需要重置代码，并重新启动车辆，因此机械师可以查看P0936代码是否返回。如果没有，那么可能会归咎于错误的触发器或间歇性错误。

If the code does return, then the mechanic will begin by visually inspecting the electrical components in the hydraulic pressure sensor system, and replacing any that are damaged. Next, the ground voltage should be checked, and then the mechanic can perform an inspection on the hydraulic pressure sensor. If no issue is found, a thorough inspection of the PCM and TCM will be required.

当修复或更换任何组件时，机械师将需要重置代码，重新启动车辆，然后再次检查是否仍检测到P0936代码。通过这样做，技术人员将知道何时解决问题。

诊断P0936代码时常见错误？

The most commonly made mistake when diagnosing this code comes from not properly following the OBD-II diagnosis protocol. The protocol should always be followed exactly, to ensure that diagnoses and repairs are thorough and efficient.

It is fairly common for hydraulic pressure sensors to be replaced erroneously, when an electrical component was the only problem in the system.

P0936代码有多严重？

在大多数情况下，尽管可能存在驾驶性问题，但仍可以驱动具有P0936代码的车辆。如果未解决该代码，则可能会对变速箱造成严重损坏，因此应立即安排检查代码。

哪些维修可以修复P0936代码？

P0936故障代码的维修是：

• 更换系统中的电气组件
• 替换液压传感器
• 在极少数情况下，更换PCM或TCM

有关P0936代码的其他评论

It is very uncommon for the P0936 code to be the result of a defective PCM or TCM, so all other options should be checked before control module failure is assumed. If the PCM or TCM does need to be replaced, then a reprogramming will be required.
