車運行的時候傳感器供電電壓和電池電壓關係大麽？

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

• 理論上是這樣，180k是麥嗎？ -soccer88- ♂ (125 bytes) () 05/04/2016 postreply 09:08:21

• 查一查，給你找到一個例子，P0420 code and battery -soccer88- ♂ (2766 bytes) () 05/04/2016 postreply 09:12:49

• 哈哈，如果你再開20萬麥一定回來 -soccer88- ♂ (0 bytes) () 05/04/2016 postreply 10:35:30

• 是麥，發動機電壓大約14伏，謝謝你的信息，我去看看 -68245- ♀ (0 bytes) () 05/04/2016 postreply 10:15:37

• 嗯，電池燈沒有亮吧？ -soccer88- ♂ (72 bytes) () 05/04/2016 postreply 10:40:33
