气踏板是一条简单的连锁,将驾驶员连接到更复杂的节气门和油门车身。通过这种连接,油门或计算机根据驾驶员对速度的需求进行所有调整。如果链接无反应,则可能是原因。在这里,根据您的车辆的品牌和型号,我们可以开始诊断并为您的无反应式煤气踏板进行维修。始终记住诊断出任何问题时,首先从最常见的问题开始。
- 笔记: Keep in mind that not all of the steps and sections of the guide will pertain to your specific make and model. There are a variety of throttle designs and a variety of different parts to accompany them.
第2部分,共2部分:明显检查煤气踏板
经初次检查后,有一些问题将使肉眼可见。始终从更简单的修复开始,然后再跳至最坏的情况。
步骤1:寻找气踏板的可见障碍物。寻找任何障碍物或物体妨碍踏板。踏板下面有什么滚动吗?路上有绳子吗?拉开地板垫,并确保不会引起阻力。
步骤2:寻找可见的油门障碍物。Open the hood and look for the throttle body. The throttle body may be exposed, while some will need to have parts removed for access.
寻找物理物质,极端的污泥堆积,某种障碍物或节气门损坏的身体。
步骤3:寻找系统中的可见损坏或畸形。Look at the linkage on the drive side of the firewall to see if the linkage straight and aligned properly.
查看发动机舱内的连锁,以查看油门连接是否直接,完整且紧密。链接中的任何额外的松弛,弯曲或断裂都会引起各种节气门问题。
假设节气门主体,电缆和踏板都正常运行,则您需要进一步研究系统及其组件,以诊断出无反应的气踏板。接下来列出的是一些会导致类似症状的常见问题。
第2部分:考虑最常见的问题
没有油门组件中的任何主要缺陷,您的问题可能会源于更难确定的事情。诊断问题的最快方法是通过涉及以下组件的消除过程。您也许可以消除最近被替换的新零件,或者您知道的组件正常工作。
If you have not do so, get the OBD codes scanned for help pointing you in a good direction. You can have this done at most automotive part stores nationwide.
Step 1: Consider the throttle position sensor。肮脏或堵塞的节气门位置传感器将不会采用准确的读数,也不会为计算机提供准确的输出。这可能会给驾驶员带来危险的结果。
这些通常可以访问并能够清洁。如果这是您问题的原因,那么简单的清洁就足够了。最坏的情况您需要replace the entire unit。
步骤2:检查是否堵塞燃油滤清器。堵塞的燃油滤清器将不允许燃油量准时到达发动机。驾驶员可以按下煤气踏板,所有节气门组件可能要求正确的燃料,但是泵在滤清器上面向电阻,无法使流动进入发动机。
If the fuel filter is clogged, the only repair that can be made is toreplace the filter。They are not serviceable units.
Step 3: Check for a faulty fuel pump。故障的燃油泵不会将所需的气体推入线和发动机。同样,如果是这种情况,所有的油门组件都可以正常工作,但似乎似乎没有响应。
到repair the fuel pump, you will want to drop the tank or access it through the access panel (if equipped). Look at the condition of the pump and make sure there are no major clogs on the intake. Assuming the pump is clean, and has failed, you will need to replace the entire fuel module. Older vehicles may have a separate pump, but most modern vehicles will include all parts into one module.
Step 4: Check the mass air flow sensor。The mass air flow sensor will tell the computer what amount of air is being taken into the engine to match it with the proper amount of fuel. The air fuel mix is critical for engine performance. If the sensor has failed and the wrong amount of air and fuel are being delivered to the engine, the driver demands will have little control over the engine. This may come off as an unresponsive gas pedal.
These are usually not serviceable, but will need to be replaced if faulty. This can be done easily, and可能需要在老化的车辆上完成。
Step 5: Look at the electronic throttle control module。Electronic throttle controls module faults are one of the most common issues when dealing with a unresponsive gas pedal.
这是一个传感器,它读取您将加油踏板按下的距离,并将信息输出到控制油门的计算机上。该信息还用于计算点火时间和其他组件。
如果模块出现故障,则汽车将以“ li行模式”运行。这是一个允许汽车以低速运行的功能,以便将车辆从危险区域移动。还有其他症状会引起油门类似的问题。
如果电子节气门控制模块出现故障,则需要更换一个或全部组件involved. Further testing is needed. Home repairs on these systems are not recommended.
无反应的煤气踏板可能会非常令人沮丧,并让您提出许多问题。有了正确的知识,令人困惑的问题可以变得清晰起来。如果您的车辆处于li行模式或不起作用,请拥有专业的机械师,例如您的机械机器人,万博体育入口检查您的煤气踏板。
