Hey guys - thank you in advance foe helping if you can. I've had a 2007 Yukon XL since new and let my kid take it to college. Now after not knowing (or not noticing) the engine light is on and the codes are above. I'm not sure where to begin replacing sensors... And it doesn't seem to me that there are any common fuses that could explain any of these codes.
Please - any help you can give would be enormously appreciated. I have no idea where to begin.
