While I am waiting for a replacement O2 extender, I decided to just put the O2 sensor into the exhaust.
One thing I noticed is the O2 sensor had a crap load of carbon on it.
Is that normal?
Also, for the HPT crowd, I don't have the SES column in Engine Diagnostics-> DTC
WTF?
Since I am getting an extender I could set P0420 to zero, but I was hoping to set it to 3 and disable SES as detailed in numerous threads.
But with the column not displaying how do I do that?
