steviej Posted July 18, 2006 Share Posted July 18, 2006 How hard is it to replace the front O2 sensor? Which bank is #1? depends on if it is sensor 1 or sensor 2. Bank 1 is the bank of cylinders closest to the firewall. Funny, this is the third time I have answered this question in two days. Must be a rash of sensors going bad. steviej Quote Link to comment Share on other sites More sharing options...

Lexus charged me $225 for same sensor for bank1 and $210 for labor. Quote Link to comment Share on other sites More sharing options...
