First of all, we must understand that the function of the fault light is to indicate that a sensor of the engine has failed. When the fault light is on after changing oil to gas, we decode it through the decoder. Most of the prompts are oxygen sensing faults (and a few are short circuit or open circuit of the fuel injection nozzle to the ground), that is, the oxygen content in the tail gas is too high, which is beyond the control range of the original vehicle computer. At this time, the computer will prompt through the fault light.
精通原车电路的师傅都知道，原车电脑是非常迟钝的，这是为了保证发动机的稳定性能。当我们的车辆经过油改气后，在发动机使用燃气时，原车电脑通过氧传感器给的电信号测算尾气浓度会越来越稀，通过不断的测算电脑会认为这个尾气浓度是正确的，就会默认。但是当转换到油路时尾气中的氧含量会突然间减小，当电脑还没有默认之前就会爆出故障，这时故障灯就会亮起。这就是油改气后故障灯亮的原因。
Masters who are proficient in the circuit of the original car know that the computer of the original car is very slow, which is to ensure the stable performance of the engine. When our vehicle changes from oil to gas and the engine uses gas, the computer of the original vehicle calculates that the exhaust gas concentration will become thinner and thinner through the electrical ** given by the oxygen sensor. Through continuous calculation, the computer will think that the exhaust gas concentration is correct and default. However, when switching to the oil circuit, the oxygen content in the tail gas will suddenly decrease. When the computer does not default, there will be a fault, and the fault light will light up. This is the reason why the fault light is on after changing oil to gas.
所以因为天然气与汽油的差别，还有现在的车型等原因一般来说这类故障时无法解决的，除非车辆燃气所需要的混合气非常浓或原车空滤器所经过的空气非常少但却达到了燃气所要求的浓度，在这种情况下故障灯是不会亮的。
Therefore, due to the difference between natural gas and gasoline, as well as the current models and other reasons, generally speaking, this kind of fault cannot be solved, unless the mixture required by the vehicle gas is very thick or the air passing through the air filter of the original vehicle is very small but reaches the concentration required by the gas, in this case, the fault light will not be on.
在这里我想建议已买新车的朋友们，如果您打算油改气还是改多点的，因为多点系统对油路的影响很小或没有影响。
Here, I would like to suggest to friends who have bought a new car that if you plan to change oil to gas or more points, because the multi-point system has little or no impact on the oil circuit.
另外，你是否装有仿真器？如果有的话，请将仿真器上的一个电位器调一下即可，具体方法详见：
Are you equipped with an emulator? If yes, please adjust a potentiometer on the lator. See the following for specific methods:
CNG/LPG电喷车仿真控制器（开环控制）
CNG / LPG EFI vehicle lation controller (open loop control)
功能：主要用于电喷汽车改装LPG/CNG开环控制系统。当燃气汽车转换到燃气状态时切断喷油嘴及燃油泵，同时向原车ECU送出喷嘴仿真信号以及氧传感仿真信号使燃气汽车在开环控制状态下能够正常运行。
Function: mainly used for refitting LPG / CNG open-loop control system of EFI vehicles. When the gas vehicle changes to the gas state, cut off the fuel injection nozzle and fuel pump, and send the nozzle lation ** and oxygen sensing lation ** to the original vehicle ECU, so that the gas vehicle can operate normally under the open-loop control state.
接线：仿真器的接线分为两束，一束为接到喷嘴的线束，一束为控制线束。安装时：1、将原车的喷嘴线束从喷嘴上拔下，插到喷嘴线束相应的接插件上，喷嘴线束上的另外一个接插件插到喷嘴上。2、控制线束中:①蓝色线接到转换开关的气态输出端；②黑色线接电源负极（搭铁）；③白色线接氧传感器信号输出端；④紫色线接原车ECU氧传感器信号输入端；⑤两根黄色线串入到燃油泵供电回路中。
Wiring: the wiring of the lator is divided into two bundles, one is the harness connected to the nozzle and the other is the control harness. During installation: 1. Pull out the nozzle harness of the original vehicle from the nozzle, insert it into the corresponding connector of the nozzle harness, and insert another connector on the nozzle harness into the nozzle. 2. In the control harness: ① the blue wire is connected to the gaseous output end of the change-over switch; ② The black wire is connected to the negative pole of the power supply (grounding); ③ The white wire is connected to the ** output end of the oxygen sensor; ④ The purple wire is connected to the ** input terminal of the original vehicle ECU oxygen sensor; ⑤ Two yellow wires are connected in series into the fuel pump power supply circuit.
使用注意事项：
Precautions for use:
⑴工作时，插座旁红色LED不停闪亮表明工作正常。
(1) during operation, the red LED beside the socket keeps flashing, indicating normal operation.
⑵输出的氧传感仿真信号为频率大约为1HZ，幅度大约为0.75V的方波信号，调节插座旁的电位器可以改变仿真信号的占空比，在安装本系统后原车ECU故障灯依然亮起时，可微调电位器使故障灯熄灭。
(2) the output oxygen sensing lation ** is a square wave ** with a frequency of about 1Hz and an amplitude of about 0.75V. Adjusting the potentiometer next to the socket can change the duty cycle of the lation **. When the ECU fault light of the original vehicle is still on after the system is installed, the potentiometer can be adjusted to turn off the fault light.
⑶本系统只适用于原车氧传感器信号为0-1V的车型。
(3) the system is only applicable to the vehicle with the original oxygen sensor ** of 0-1v.
⑷本系统工作电压为10-16V，安装时应远离高温、潮湿位置。
(4) the working voltage of the system is 10-16v. It should be installed away from high temperature and humidity.
