    Hey all. wanted to see if anyone would be able to figure out what might be causing these two codes to pop up. I scanned my car the other night and the codes B14B8 for Temperature sensor/circuit range performance and U023A for Lost Communication with Image processing Unit A came up on the scan.

    There’s no check engine light on my dash and the ADAS system is working fine and AC is blowing ice cubes. Could it possibly be caused by OpenPilot being installed? I haven’t experienced any other issues thus far so I’m thinking of just keeping an eye on it for now
