Hi i am determined to find out what is my remaining problem with the check engine light coming on then going off. It is now on all the time. I replace the heating element bank #2 the light went off two days then returned. Need some really good advice, i don't feel like bringing it to the shop. My code reader still says heating element bank #2.

really? mine said that the o2 sensors were out even tho i replaced them about 10k back. i just ignore it.

you have to be specific seinna has sensors like

bank 1 sensor 1
bank 1 sensor 2
bank 2 sensor

there are 2 sensors before the catalytic convertor and 1 after the catalytic converter
