P-0606 code Help?
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???
- Engine Control Module (ECM) Harness power supply circuit is open or shorted
- Engine Control Module (ECM) Programming
- Faulty Engine Control Module (ECM)
Help with this
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.

When is the code detected?
Indicates the PCM has experienced an internal memory fault.
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine may not start
P0606 CHEVROLET Description
The Engine Control Module (ECM) continuously monitors its internal memory status, internal circuits, and output signals to the throttle actuator. This self−check insures that the ECM is functioning properly. If any malfunction is detected, the ECM will set the code and illuminate the engine light.

Start looking for shorts near the PCM ... frayed wires, +12v wires that have rubbed through and contacted metal, etc. :(

I am going to take it to my buddy's work tomorrow. He is going to run for code again and reset it.

It's under the hood, my buddy has an '04 and I think I remember seeing it on the driver's side. If you have an owner's manual, it should be in the pic of what's under the hood.
Sometimes, the problem is a loose/poor PCM ground. A lot of PCMs have been tossed out, when all that was wrong was a bad ground.Ray

I did some research on it. It seems that many times a program flash or update will fix the issue. Most dealers charge around $135 to check what version program you have and then will upgrade it if you have an out of date program.
