Oxygen Sensor 850 1997

posted by  someone claiming to be Sonny on  Thu Sep 16 08:16 CST 2010 [RELATED]

My "check engine" light came on and the scanner reads "Ductbank 2 - Rich Fuel Mix" - is ductbank II the front or rear oxygen sensor? I want to make sure that I replace the right one - thanks!

    LOL. Your car only has 'bank 1'. 'Bank 2' is for V or H designed engines, not straight engines.

    I have never heard of a ductbank, that must have been from a scanner built in Bangladesh!

    Hold on a minute! Don't replace the sensors until you've checked/repaired any potential vacuum leaks. Your sensors are likely fine, they're just telling the engine to pump in too much gas to use the unmetered air that's being sucked into the engine. Search here on "vacuum" and you'll find scads of posts on vacuum leaks, the nemesis of fuel injected engines, and likely culprits, starting with all the little rubber elbows that crack and fail with age (kinda like me).
