车引驚灯时不时亮

[hahaid]

Corolla, 12万公里。 夏天没有发现这个问题。冬天冷了时不时亮着。网上看了一下说油箱盖没拧紧。拧紧后确实好长时间不亮。发现确实经常锁不紧, 因为塑料老化了。买了一个原装油箱盖装上应该没问题了。结果很快又亮了。发动机感觉工作正常。板上有否大侠知道怎么回事吗? 莫非又要花银子了。多谢

Find fuse box, pull out EFI relay than put back. if light goes off. 100% that is EGR valve.

Would you please tell me What is EFI and EGR?

EFI = ELECTRONIC FUEL INJECTION
EGR = EXHAUST GAS RECIRCULATION

Go to garage to get code, most cases are gasket.old gasket has default.

到princess auto 买个便宜的OBD II code reader, 把code读出来，就容易知道哪儿的问题了，否则就是瞎猜。
code reader 以后后可以用，划算。
