im trying to change the oxygen censor where is the number 3 bank?
i have a 1997 saturn coupe on 1997 Saturn SL
There's no number 3 bank. What is the trouble code?
A four cylinder engine should have codes set for Bank one sensor one or Bank one sensor two.
only 2 oxygen sensors. one is located in front off the exhaust manifold and other is under the vehicle near the cat. Never heard of a 3rd bank
