in a really cold morning (-8 F), i tried to start the car and it hesitated a little bit but it started, also threw a CEL p0141 "O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)". i tried to clear the code but it came right back on the second time i start the car. i searched the forum and only 5 posts came up so i guess this is a rare code. and only one person came up with the solution of replacing the rear o2 sensor... i wonder if theres another other things i can do to fix this besides getting a new o2 sensor... i really need to get it fixed because i'll be trading in/sell my evo soon ... thanks for any help.

 

if you know anyone that has ecuflash you can just disable it.....

 

i might call ams later and see what they think...
anyone else has or had this problem???

 

this code just popped up for me too! I'm guessing the rear o2 sensor just went bad....

help?

 

yea me too....help?

 

I get this one too.

Guess it is time to just disable it.

 

yea disable it or replace it. if problem persists you may have a bad cat. so get a test pipe and disable it lol.

 

or sell the car. i did...

 

I just got this code yesterday too.
