Thank you for the response, I'm going to look into the information yall have sent me, I'm sure me and my girlfriend's dad will figure it out once we find the area of the problem. Please keep the information coming as it will help me and anyone else Into the future who needs support and stumbles upon this thread.

Need some help, my 2005 Legacy 2.5GT 5EAT has been showing a ERR message randomly, sometimes it flashes, sometimes it's just steady, and It appears and disappears randomly. I only found a few things on the forums that didn't help. My car is bone stock, and I'm pretty sure it has never been modified in the past, it has a new EJ257 shortblock that was put in a year ago. Any idea on what might cause it or what might fix it? 20231201_132344.heic
