i have an 04 cobra with the check engine light on.i scannd it and it tells me the code p2270 which is the o2 sensor stuck on lean,bank1 sensor 2.what is the bank 1 sensor 2 mean? they took down the transmission and when i got it back is when i started to get the light.could this have been if it was installed wrong? cuz i seriously doubt an 02 sensor would go bad in 2 years of use its almost new car only.thanks in advance.

 

if this happend after you got your car back...take it back and have them fix it


they would of had to unplugg the O2's so they could of messed one up
