I see the upstream one by the firewall, and the downstream under the floor board. I couldn't see any upstream however to the front of the car.
Does the vibe have a set for each manifold? or is there only 1 set after the exhaust combines?
not sure why I was thinking the engine was a V configuration - hence looking for front and back oxygen sets.
Maybe I was just wishing it was a V6!! Been working on my Taurus too long.....
Yes, it's an inline 4 - so that would answer my question - it should only have 2 sensors, 1 upstream and 1 downstream.
it's the upstream one I'm after.
From what I've seen, the heat shield needs to come off first......project for next week!
Anything after 2004 has an A/F sensor upstream, by the way. Downstream is always a normal O2, though. Just for reference for anyone who searches later.
