My light just came on. I ran up to Auto Zone to get a code. I got code P-0606.ECM internal fault. This is what I found. I don't know where the fuse is. I don't have a book. I will go out and check in a minute. Anyone have any experiences with this???

Possible causes
- Engine Control Module (ECM) Harness power supply circuit is open or shorted
- Engine Control Module (ECM) Programming
- Faulty Engine Control Module (ECM)

Tech notes
Check the PCM fuse, if fuse is OK try erasing the code first and if the code comes back you may have to reprogram or replaced the PCM.
