I have been battling the on again off again CEL running a catless downpipe. Im also running the titan ProTune. What is interesting is most others are not reporting a issue. So here is what ive done and where I am at.
The shop that installed the downpipe used their own O2 spacer and I was having issues with the below codes. So I swapped that O2 spacer for the fabspeed 02 spacer and am still getting the same issue. the codes im getting are as follows. Ive verified there is not actual disconnection of the 02 sensor. Any ideas?
12ab04 oxygen sensor after catalytic converter, electrical line disconnection
12b701 oxygen sensor heating after catalytic converter, function: internal resistance too high
I want to make sure that this is a product of the catless downpipe and piggyback and not haveing a ECU flash that can suppress those warnings vs some other issue.
