What code is that? I don't have that in my shop manual or online.
P061b was another code


some people claim that code is cause by using mismatched tires

the Controller Area Network bus communications CAN bus. went down(This tahoe is equipped with Can bus support)


that only thing that worked was the electrical power steering.

i did get a car wash the other day but just the outside only..

i'll put in the original MAP sensor maybe the new one is faulty..

the battery is less then a year old

Wait- did you just put in a new MAP sensor before you got that P0069? If so, why? There must be a reason you held onto the old one, maybe you weren’t sure it was bad. What brand did you install?

@BG1988 I had crazy electrical issues including truck not starting to losing power on the freeway after a carwash one day. It ended up being the negative battery cable. I could tell because when I jiggled it my electrics would flicker.
