- 1996 Explorer XLT
I looked through a lot of post on this forum before posting my problem, but I’m seeing a lot of controversy out there further confusing me.
I’ve got a 1996 Explorer 4x4, 4.0L, 6-cylinder with a check engine light (code: P0133). The printout Autozone gave me for code P0133 stated the bad O2 sensor was closest to Cylinder # 1, Bank 1. My Haynes manual says P0133 relates to the “Upstream” O2 sensor Bank 1. So far, I’m pretty sure upstream means the sensors between the engine and cat converter. Underneath my Explorer I found two O2 sensors; one on each side of the Explorer, between each exhaust manifold and the point where they met before the cat converter. The exhaust pipes met just before the cat converter on the right (passenger side) of the Explorer.
My question is this: What side of the engine is Cylinder # 1 on, and which O2 sensor do I replace, driver or passenger side?
Thanks a bundle!
