but we "assumed" it was the sensor and swapped it. No dice. Turns out the harness was rubbing on the cat heat shield and had either gone open or shorted to ground,



Was just under there the other day looking at both sensors, just change the rh side. Harnesses looked fine. But thanks, it's happened to me too in other situations. Left over "Test-parts" are great. Live and learn.
