    Were you able to straighten then and clean them to get them to work?

    So here is the update: after swapping the plug,it cleared the p malfunction error. The problem now, it still won’t start as if the engine is locked. I know the engine is not locked. Without the transmission in it turned smoothly. It also turned when installed the transmission. But once I tried to start it with the error cleared, it locked up.

    here is my question, I the car was bought new from dealer. I called and got all the records emailed to me. Then I fount the record below. Look at the highlighted area.
    What are the symptoms of a bad investor. Does it lock up the mg1 and mg2 motors?
    Is there a way to test the inverter or just swap it out?

    It looks like the inverter was replaced. Is that what the term, remedied, indicates?

    I think it was just flashed.

    Is the hv inverter the same as the hybrid powertrain control module?

    Going to dig back into it tomorrow. Was waiting to hear if anyone knew if the hv inverter is the same as the hybrid powertrain control module?

    A quick google (' hybrid powertrain control module') seems to indicate that it's a separate item. May have things to do with the inverter, but it ain't the inverter.

    Ok guys. I finally gave in, and had it towed to an independent shop. The diagnoses, the integration really burned up. He also told me, that shortened the hybrid battery. So, $300 to get my car back, but it still needs a hybrid battery. At this point, do you think that I can just rebuild the hybrid battery? I figure I can test and replace the bad modules.
