Think I replied to you on Facebook as well.
1144 Error is a PEM Fan Problem.
If you havent had an anual service in a while, you might try that. They take the PEM off and clean everything for $600.00.
If you haven't replaced your PEM FAN, that would be my first guess. Costs about 1K at Houston SC where I had mine done.
2nd thing to look at is the PEM connector that is right below the PEM. There are a few threads discussing how to access it and look at it.
You can order the plug from Tesla or you can order yourself from Digikey or something similar
Molex PEM Connectors
Fan Plug
19418-0004 Automotive Connectors 4CKT RECPT 14-16AWG
0194200009 Automotive Connectors MX150L 14-16 AWG HPA FE SN
From Tesla its
1017064-00-A - CONN, CLIP.LCK, MISC, 004P, CBM, HSG $17.00
Its tight to replace it, but it CAN be done without removing the PEM,
If your good at electronics and crimping pins, you can easily do it yourself. Just takes a bit of patience.
Id Suggest you also look at the connector at the PEM and well, inspect for any corrosion. You can use a phone camera with video so inspect it.
Mine before I replaced the connector looked like. Lots of damage and corrosion on plug pin #1 on the connector which causes the 1144 error.
Bottom of the PEM Plug looks like
Some small corrosion on the mirror pin #1. I just used cleaner and replace just the PLUG on the fan harness.
PM me if you need more details...
