Great write up. I completed all the steps listed but trying to reset the ECM is not working for me. My service manual says hold both up and down buttons and turn key on, then release and press up, down, up, then instead of N it will show --, then Im supposed to open throttle to full and fully close and the indicator should read N again. No matter what I do I cant get it to read N again. When Im not trying to reset the error code 6 reads on the display(6 short flashes of --). So that means angle sensor problem. I dunno what to do, dont want to bring it in and spend lots of $$, just bought this thing in the fall. Been trying to fix this for weeks. Any suggestions on how to reset the ecm before I light the thing on fire?
