That sensor is located on the right (rear) bank exhaust manifold. It means just what it says. It's getting old and slow. Clear the code and see if it returns. If it keeps returning, R & R the sensor.
I can't figure out which sensor to change. Is the rear exhaust manifold on the right front of the car near the radiator or is it the one on the left side near the dashboard, if I'm facing the car?There are 3. One on each exhaust manifold and one after the CAT. Bank 1 Sensor 1 is located on the right (rear) bank exhaust manifold (by the firewall).
Do you feel any difference in the throttle response?Well i just did this sensor on my 96 seville and boy what a job.
My problem was right where the sensor is theres a bar of some sort that runs across and kind of makes it hard to get the 02 sensor socket on it.In fact i got the socket stuck on there a few times.Got it off though and installed the new one.I had to buy a 10" extension to get mine off.Like ranger said its doable but not too easy!Especially with my big forearms and hands.:thumbsup:
Are you guys talking about the strut tower brace? Why didn't you just remove it? Six easy to get at bolts and it is out of the way.My problem was right where the sensor is theres a bar of some sort that runs across and kind of makes it hard to get the 02 sensor socket on it.
I think you may be describing a coolant pipe? ( Twin 1/2" pipes strapped together ) ... I forgot about that thing...Hmmm not sure ranger! This bar i could not tell what it was for but it was sitting like allmost on top of the sensor.Could not see or tell what it actually went to and couldn't see any bolts to get it off.
