2001 turbo car multiple codes

Post by thebackcourse »

A friend's s80 Turbo car is, best that I could tell running fine with a slight surging sensation when in gear but at idle. IT accelerates smoothly, no jerky acceleration but it's got a CEL and when I scanned it gave the following codes:

P1132 280A Heated oxygen sensor (H02S) 1, bank 1 – signal high
P1152 290A Heated oxygen sensor (H02S) 1, bank 2 – signal high
P0136
P0140
P0156
P0161
P0302
P0447
P0455

Most if not all seemed to be o2 related...but it's hard to figure out if it's the o2 sensor(s) that are bad, or something else is wrong but it's registering as issues with the o2 sensor?
