Whats a signature?

There's a way to do a pin point test on the sensor. Not sure how nut there is a way. Not all the time ot will throw a code. Like I said it may be biased. May give the ecm 1 reading but it could be measuring bad so it could cause more fuel to be burned.

White balt signature. Like mines on bottom

No they haven't.. seems to be getting worse.
Going in tomorrow and getting a trans flush, new fuel filter, and tire rotation. Hopefully that helps...

As a full time mechanic i know No auto maker recommends using engine/trans conditioners at all .If u wanna have a long lasting good running engine do not wait till oil life is low .Ive serviced many gas/diesel engines and the ones that had the oil done on time or earlier didnt have any gunk/sludge inside .I change the oil in my cars every 3000-4000 miles tops with synthetic oil -at coast 30 bucks i dont think u can go wrong ,plus i have never seen engine ever damaged by changing oil too early , changing late ..... thants another story
