What is the Oxygen Sensor all about?

\n\n

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor.

\n\n

Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor.

\n\n

If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.

When replacing the oxygen sensor remember:

\n\n\n\n

How it's done:

\n\n\n\n

Our recommendation:

\n\n

Keep up with the tune-ups. If check engine light is on, don't drive the car too long without getting it inspected. If check engine light is flashing, pull over and get the car towed to avoid costly repairs. Ask the mechanic to inspect the vacuum hoses and leaks in the exhaust system. If the vacuum hose or exhaust system is leaking, it will display an oxygen sensor fault code. Replacing an oxygen sensor may not fix the problem.

\n\n

What common symptoms indicate you may need to replace the Oxygen Sensor?

\n\n\n\n

How important is replacing the oxygen sensor?

\n\n

Your vehicle has multiple oxygen sensors, and they all help the car run optimally. The front sensors measure how much oxygen is in the exhaust stream to measure how rich or lean the gases leaving the gas chamber are. The rear sensors measure the oxygen content of the gases as they leave the catalytic converter. The oxygen sensors then relay this information to your vehicle\u2019s electronic control unit, so that it can adjust as necessary. Because cars depend on an ideal fuel-to-air ratio to function optimally, the oxygen sensors are leaned on for engine performance. When your oxygen sensors fail your car will run less smoothly, get worse mileage, and have worse emissions.

氧传感器更换服务

氧气传感器是关于什么的?

每一年,制造商都会增加更多的氧气传感器,以更好地管理引擎运行。一些高性能发动机的每个气缸都有一个氧气传感器,以及每个催化转化器的后部。传感器位于引擎盖下方或汽车下方。氧气传感器连接(拧)到排气管道,在前面或后面的催化转换器。前面(上游)传感器测量排气系统中的氧气量。前氧传感器的目的是测量气体在离开燃烧室时的富或贫程度。根据废气是贫(含氧量高)还是富(含氧量低),进入发动机的燃料量由发动机管理计算机进行调整,以尝试和维持一种理想的混合物,使催化转化器的排放量最低。

后(下游)传感器位于催化转换器的后面。后部氧传感器的目的是监测离开催化转化器的废气中的氧含量。

如果一个或多个氧气传感器出现故障,您的汽车可能无法通过排放测试。如果你的车有一个有缺陷的氧气传感器,你可能会得到可怜的油耗,它可以损坏催化转换器。

氧气Sensor-MATROX-1

更换氧传感器时请记住:

  • 许多氧气传感器因泄漏的油或冷却剂而损坏。如果是这样的话,就需要找出泄漏的原因并进行修复,否则更换的氧气传感器也会损坏。
  • 新的汽车需要特殊的氧气传感器,而不是1996年以前常见的通用传感器。

如何做:

  • 扫描车里的电脑寻找密码。
  • 检查排气系统是否有真空泄漏和气孔。
  • 如果氧传感器损坏,请拆卸并更换氧传感器。
  • 检查电气连接。
  • 检查氧气传感器是否正常工作。
  • 明确的诊断代码。
  • 测试驱动的汽车。

我们的建议:

跟上调整的步伐。如果检查引擎灯亮,在没有检查的情况下,不要驾驶汽车太长时间。如果检查引擎灯闪烁,靠边停车并把车拖走,以避免昂贵的维修。让修理工检查一下真空软管和排气系统的漏洞。如果真空软管或排气系统泄漏,将显示氧气传感器故障代码。更换氧气传感器可能无法解决这个问题。

哪些常见症状表明你可能需要更换氧气传感器?

  • 检查发动机指示灯是否亮。
  • 汽车的油耗越来越少了。
  • 排放测试失败。

更换氧气传感器有多重要?

你的汽车有多个氧气传感器,它们都有助于汽车最佳运行。前面的传感器测量排气流中有多少氧气,以测量气体离开气体室的浓度。当气体离开催化转换器时,后面的传感器测量气体中的氧气含量。然后,氧气传感器将这些信息传递给车辆的电子控制单元,以便在必要时进行调整。因为汽车依靠一个理想的燃料空气比来实现最佳功能,所以氧气传感器依赖于发动机的性能。当你的氧气传感器失效时,你的车就会跑得不那么平稳,行驶里程变差,排放也会变差。
