Read only memory code

[stangn]

I had my car down with no battery power for several months while building a new motor. When I got it back up and running I got a P0605 code. Cleared it several times but keeps returning.

I've rechecked all my grounds and checked all the computer pins at the plugs but it's not helping.

Anyone have any ideas?

A KAM Reset and then clear whatever code comes up might do the trick?

This worked for me when I had a code stuck.

Try and reflash the stock tune to the pcm. Check for the code then reflash the aftermarket tune.

Who tuned the vehicle?

I had this code pop up after leaving the dealer once. I think they disconnected my battery, but I forgot for what. I did what basspro recommends and everything went back to normal. It would not reset by clearing the code alone.

Sorry been away for a bit.
Thanks for the help.
It's tuned by a local guy. I did the Kam reset and crank relearn. Put stock tune in and reloaded the other. It still comes up but not regularly now. Talked with my tuner and he thinks it's battery voltage. My car sits a lot without a tender so I ordered one. Battery was low but still started the car ok.

P0605 pops up with SCT tuned Ford ECU's due to the incorrect way SCT calculates the Check Sums.

Thank you Shaun. I feel better about this now. I can relax lol.
