问：引擎失火和牵引力控制

嗨，那里的失火（取决于严重程度）可能会在车辆中产生足够的震动，以引起牵引控制系统以检测车辆稳定性的变化。这traction control system在检测到失去牵引力时，请监视车辆的转向和稳定性。这是通过在与动力总成控制模块（PCM）通信的四个车轮中的每个车轮中使用电子传感器来完成的，以在不利天气条件下进行转向性能和稳定性。牵引力控制系统通过降低发动机速度并确定要施加制动压力以防止车辆滑动来起作用。防锁制动系统和牵引力控制系统共同工作，以保持车辆的稳定性。计算机使用从电子传感器接收到的有关每个车轮旋转速度，车辆的水平运动以及车辆的垂直运动来确定如何指导牵引力控制系统或反锁制动系统来最佳控制的信息，以最佳控制需要时车辆。当此警告指示灯在仪表板中亮起时，这可能表明了几个问题，例如车轮速度传感器故障，转向角传感器故障，旋转速度传感器故障或转向架的问题。在某些情况下，牵引控制系统可能只需要重新编程。此外，当发现任何这些症状时，某些车辆可能会进入li行模式，使车辆无法加速约30英里 /小时。

引擎失火can be caused by many different problems and are generally caused by either a spark or fuel issue or in some cases, a combination of both. Spark related problems generally will result from things like ignition coils, crankshaft position sensor, spark plugs, spark plug wires or ignition modules not working properly. When the misfire results from a fuel related issue, this is commonly related to a lean fuel condition (lack of sufficient fuel supply to the motor). Fuel related misfires can be caused by many different things such as low fuel pressure, faulty or dirty fuel injectors, a faulty O2 sensor, a dirty or failing mass air-flow sensor, a faulty or dirty idle air control valve or a vacuum or intake leak. When the fuel supplied to the combustion chamber is insufficient, this results in an ignition (spark) that is igniting a less than balanced load of fuel and air. This results in a misfire or an explosion in the cylinder that is much less powerful than the other cylinders. This creates a loss of power that resonates throughout the motor additionally causing other problems with ignition and fuel timing. Due to the number of different things that may cause an engine misfire, the quickest and easiest way to diagnose this type of problem is to hook the vehicle up to a scanning tool which will download any potential fault codes that may have registered in the vehicle’s computer as a result of the poor running condition. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
