o2 sensor replacement

JC888 · 08-16-2018, 02:28 PM

Hi All,

Can someone confirm if the subframe and/or downpipes need to be removed to replace the upstream o2? I think my bank 2 o2 is on the way out and wanted to get an idea on what I'll be dealing with.

Thanks in advance.

Easier to do from the top and right wheel well. Right where we'll gives good access to upstream O2 sensors and it's then just a matter of routing around the valve over and connecting correctly at the harness
