车运行的时候传感器供电电压和电池电压关系大么？

01 camry 180k, never changed cat, 26-28 mpg always

as I understand it, o2 sensor has to be heated up to work properly when engine is running.  At that time, battery voltage should not matter.  So that is the confusing part here to me

• 是麦，发动机电压大约14伏，谢谢你的信息，我去看看 -68245- ♀ (0 bytes) () 05/04/2016 postreply 10:15:37

• 嗯，电池灯没有亮吧？ -soccer88- ♂ (72 bytes) () 05/04/2016 postreply 10:40:33
