So I get CEL on dashboard and get OBDII codes P013A,U0401:00, u3003:16. Vehicle showing no signs or symptoms previously except door actuator clicking constantly when cold outside and occasionally interior lights misbehave. I hear U codes are generally not a big concern but I’m wondering if I should be concerned with those symptoms? Also, could it just be that the 02 sensor issue is triggering these codes because I got all three all of a sudden. Is it possible these codes are only coming up with CEL because I need to change 02 sensor? I’m terrified to go to dealer because my previous vehicle from them went in for 02 sensor and never returned with them stating pcm went bad and even after changing it they couldn’t figure out issue. (That’s a whole other story but you can see my mistrust with their abilities and their trash vehicles since the previous gave issues from day one of having it)
