LAND ROVER DISCOVERY 2 SENSOR PROBLEM

2003 Land Rover Discovery 2 • 113,000 miles

Are the 4 HO2S (O2) Sensors on the Disco 2 the same or are the 2 pre-catalytic different than the post-catalytic.

They are very likely all different. Upstream and down stream are definitely different and sometimes left and right are too.
