DTC P0421 Bank 1 Warm-up Catalytic converter not effective enough
DTC P1131 Bank 2 heated oxygen sensor 1 - Internal resistance too high
I got the same 2 codes from the DEQ as I tried to pass my deq test. My plates are now expired and am driving the car illegally until I get this fixed. I called the deal and they're saying it could be as much as $1300 in parts for the catalytic converter plus labor. Which of course, i'm not prepared to pay. So I hope I can get this thing fixed some less expensive way.
They also told me that there may be a software upgrade that would fix certain problems as the old software that came with some vehicles is too sensitive. (Still have to pay for that too. I think I shouldn't have to pay. But.)
Would you please tell me your oppinion?
Thank you in advance.
have the same problem?
