Hi all 2004 TB first i had a cel code 136 so i changed the o2 sensor it was fine for 4 weeks.
Then i got code 141 i cleaned the contacts then got code 137 so i took the o2 sensor back and got a new one.
Now i get code 141 again wires and contacts look good now i'm stumped.
Anyone have any ideas???????
Did you use Bosch or AC Delco. Code P0141 (I put it in the standard format to help the search engines) fails very often if you use Bosch brand. Run a search here for more information about "P0141".
Seriously, there's a search button (are you having a hard time finding it?) and you just type in P0141 and read up for a while. Are you browsing a technical site with a phone? That's not always a good idea.
have read that bosch is crap so will replace with a ac delco also peaople say it means the cat is bad don't see how truck runs fine.
