起亚 P2096 催化器后燃料调整系统太差(第1组)。

诊断和修复起亚P2096催化器后燃料调整系统过低(第1组)。

起亚不断监测上游和下游的氧气传感器,并不断改变燃料调整,以补偿富/贫读数。 为了正确诊断起亚P2096,在扫描工具上读取上游和下游氧气传感器的实时数据。

拧入氧气传感器

上游传感器应迅速从低电压切换到高电压,而下游传感器应保持在0.6-0.7伏左右。

如果你的读数显示在下游氧传感器处快速切换或以较高的低速率切换,这可能是一个迹象:

1)发动机上的真空泄漏。 检查从空气滤清器箱到节气门体的空气管道是否有裂缝。 检查真空管道是否有裂缝或脱钩。 检查进气歧管内和周围是否有真空泄漏。

2) 催化器前面的排气泄漏。 测试时,将车间真空吸尘器连接到 "吹气 "模式的尾管上。 用一个装满水和洗洁精的喷瓶,喷洒排气系统的每个接头,寻找表明有泄漏的气泡。 根据需要进行维修

3) 断开与下游氧传感器的连接,并检查端子情况。 清洁任何腐蚀,并将雄性端子扭转约10°以获得更好的连接。

如果问题仍然存在,请更换下游的氧气传感器。
