Guys,

Been wondering... how do v actually fix the problem? I knew its not a major issue, but I was worry that what if the CEL not trying to tell us only about the O2 sensor?

Saw some ppl saying that he terus remove to 2nd O2 sensor... but how will that help actually? Once 2nd sensor removed... no signal send to ECU... then CEL on again.. I know there is another option which is to remove the CEL light connection.. but arent our CEL tells us other things as well beside the O2 sensor?

Please tunjuk ajar sikit.... Thanks
