code help....
I just got back from autozone where I got my codes read because my check engine light came on several days ago...I got:
P0400, the PCM has determined that a malfunction exists in the EGR flow,
P0150, PCM has determined that a malfunction exists in the electrical circuit for O2 sensor 1 in bank 2
P0130, PCM has determined a malfunction exists in the electrical circuit for O2 sensor 1 in bank 1....
WHat could be causing these problems? Do I just need to replace O2 sensors or could the problem be deeper? What about the EGR flow? How do I tell what exactly is wrong?
