P0636代码定义

The P0636 trouble code detects an electrical error with the power steering control circuit.

What the P0636 code means

The P0636 code is a generic OBD-II trouble code that signals an issue with the power steering control circuit. The power steering system, which helps make steering easier for drivers, constantly sends data to the powertrain control module (PCM), and other control modules such as the antilock brake control module, traction control module, and fuel injection control module. When any of these control modules detects a power steering control circuit issue, which usually comes from an abnormally low voltage reading, the P0636 code will be detected.

是什么原因导致P0636代码?

Possible causes for the P0636 trouble code include:

  • Faulty power steering pressure or position sensor
  • Damaged electrical components in the controller area network (CAN) bus
  • Loose or damaged control module ground wire or ground strap
  • 在极少数情况下,公共汽车有故障

P0636代码的症状是什么?

The P0636 trouble code will often be accompanied by the Check Engine Light, though the vehicle may need to detect the issue multiple times before the light appears. The power steering system will likely be disabled, making steering heavier and more difficult.

How does a mechanic diagnose the P0636 code?

The P0636 code should be diagnosed using a standard OBD-II trouble code scanner. A certified technician can use the scanner to view the freeze frame data and assess the code. The mechanic will also note the presence of any additional trouble codes, as codes should always be taken care of in the order in which they appear on the scanner. The codes will then need to be reset, and vehicle restarted, so that the mechanic can check to see if the codes remain detected. If they do not, then the vehicle likely has an intermittent issue, or had an erroneously triggered trouble code.

If the P0636 code remains detected following the restart, the mechanic should perform a visual inspection of all the electrical components in the system. All wires, connectors, and fuses will need to be examined, and replaced as necessary. The control module ground wire and ground strap should then be inspected, followed by the power steering pressure and position sensors.

If the issue still remains, then a CAN scanner can be used to diagnose the CAN bus and potentially identify the problem.

更换任何组件后,机械师将需要重复重置故障代码,重新启动车辆并检查是否存在代码的过程。当故障代码消失时,这将有助于告知机械师,并且维修成功。

Common mistakes when diagnosing the P0636 code

The most frequently made error when diagnosing this code comes from a failure to follow the OBD-II diagnosis protocol. It is essential that technicians obey the protocol step by step to make sure that all inspections and repairs are efficient.

It is fairly common for this code to be addressed before other trouble codes that precede the P0636 code on the scanner.

How serious is the P0636 code?

A P0636 trouble code will not keep a car from being drivable, but it will likely make it more difficult, and therefore dangerous to drive. Power steering is a very important feature, so vehicles with this trouble code should be inspected and repaired as soon as possible.

哪些维修可以修复P0636代码?
