氧气传感器

Hello everyone, I am new here, I have a Hyundai Accent 2000, supposedly ... 1.5,
a few days ago, I had to change the escape manifold and not the mechanic did not find the same type of engine, I found only one without Catalitical, and put that one, but, it throws me codes of llos of oxygen sensors, in addition the car does not pass the 3000 rpm because it is stopped and the engine is scratched ... The strange thing is also that the氧气传感器的馈电是12伏，但是当我测量进料时，它会给我带来22伏的超高电压...（以前不是这样）我不知道我是否会损坏计算机...，我不知道有人可以得到Hyndai Accent 2000的手册和工作企业，谢谢2000。

您好，Landa探头有4条白色电缆1黑色1灰色，探针不是在电流上供电，这取决于排气管内部的氧气，但对于在两个白色电缆中已经连接的加热阻力具有12V的损害电压度量
