    Multiple codes p0101, p0141, p0140

    P codes Hi thanks for your reply, I tried some mass airflow sensor cleaner and the lights stayed off for a while then came back on. I ended up replacing my mass airflow sensor as well as both O2 sensors behind the catalytic converters. So for all is good. Thanks
