After cleaning dont forget the dielectric grease. It will help it from hapening again.The green wire pin was corroded.
For my first post in the forums...In the picture above, this is C146. The green wire pin was corroded. Gave me all sorts of codes, P0446, P0155, P0135, P0161, P0141.
The corrosion was just a small green, blackish looking dot on the pin.
Good luck.
Thanks everyone for the post above.
What do you clean it with?For my first post in the forums...
THANK YOU.
I bought this 2012 knowing it had the CEL on and a few issues. Replaced all 4 O2 sensors anyway. Fought with the codes as stated above as well. Just now pulled open the plug to see a minor black smudge on the pin. Cleaned it, dielectric and put it back together. Cleared codes and haven't seen those pop up again. Thank you for answering your own post. It helped.
