有可能是上次换机油晚了

电脑提示的

找个什么地方clear一下就ok了

也有可能是提示换机油什么的， 找到可以接电脑的地方， 就知道了～

怎么接电脑？手提电脑可以么？麻烦你给下详细方法

可能和EMISSION有关

there should be a code recorded in the auto's computer and go to the garage to get it read, then should know what's wrong.

如果没换油,通常是另一个灯.
这个灯通常是和emission有关.
常见的是,油箱盖不紧,O2,催化转换.

给你个例子,1个月前,我有个车要做e-test,都约好了,结果早上灯亮了.
用scan一查,P0420,不理它,把灯灭掉.过了两天去测.
污染只有limit的八分之一.

My car had this problem one or two years ago. I went to dealer for a check. I was told it was caused by malfunction of the oxygen sensor. The only impact was the engine might generate more polution. Although the impact was minor, I still paid for replacing a new sensor to get rid of the warning signal. Otherwise, in case there is a real problem, you may not know how serious it is.
