cosmicfireball Posted June 30, 2004 Share Posted June 30, 2004 ....should one replace this part...are there any indications that it should be changed? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
jzz30 Posted June 30, 2004 Share Posted June 30, 2004 not sure how long they last or at what interval they are recommended to be change at but eventually your car will flash a check engine and if you pull the code your car will tell you when she wants an new one Quote Link to comment Share on other sites More sharing options...
cosmicfireball Posted June 30, 2004 Author Share Posted June 30, 2004 Thanks....but would it be to the engines advantage to change it BEFORE the code comes on? Quote Link to comment Share on other sites More sharing options...
soarer479 Posted June 30, 2004 Share Posted June 30, 2004 hmm on an 02 sensor you should be fine just wait for your engine to throw a signal and scan it to make sure thats the problem then simply replace Quote Link to comment Share on other sites More sharing options...
jzz30 Posted July 1, 2004 Share Posted July 1, 2004 well then just change it every 80-100k miles or so Quote Link to comment Share on other sites More sharing options...
johnny3 Posted July 1, 2004 Share Posted July 1, 2004 I'd wait til it sets a trouble code, I've seen the O2 sensors last 200k plus. Quote Link to comment Share on other sites More sharing options...
cosmicfireball Posted July 1, 2004 Author Share Posted July 1, 2004 Thanks for your suggestions...I'll wait 'till it 'throws the code'....I guess it is placed under the 'if it ain't broke,don't fix it' category.... Quote Link to comment Share on other sites More sharing options...
