Hi guys; i'm swapping out my dpfe sensor because of dtc codes.
Could someone tell me please, which pipe goes where.
On my sensor it says REF and HI.
I need to know if the top pipe on the exhaust goes to REF or HI.
I know the pipes and hoses are different sizes ... i just need to know if REF goes to top or bottom (upstream/ downstream on the exhaust) .... thanks ....G.
