no1kicker Posted December 10, 2002 Report Posted December 10, 2002 Every once in a while (I mean maybe once a month) my SES light will come on when I am driving slow (~30 mph) after driving for a little while. I finally grabbed a code for it today and it gave me 45, which is the O2 sensor - rich exhaust. http://www.w-body.com/ecm-codes.html#45 Since this rarely comes on, is it anything to worry about? And what is the first thing to try, maybe replace the O2 sensor? Thanks for the help. Quote
msvestka Posted December 10, 2002 Report Posted December 10, 2002 The most likely cause of a code 45 is leaking injector or two. It's not uncommon for these cars, especially as the injectors get old with lots of miles on them. Quote
god910 Posted December 14, 2002 Report Posted December 14, 2002 Anytime anything breaks it will set an 02 code LOL. Quote
