I got the p1472 error code. also found the VIS motor technical bulletin
when i checked VIS motor 2 the the intake flap control arm does not move how it is supposed to.

do i need to replace the whole upper intake manifold or is there another way to fix?

 

I vaguely recall reading somewhere that the entire upper intake needs to be replaced for that symptom, but hopefully someone in the know can chime in.

 

ignore the code, VIS motors so rarely cause problems its hilarious how many non lr shops put new motors in only to find out the misfires or other issues are causing the problems.

Get all the codes read. Not just those two.

you might find your bill is alot cheaper and alot quicker diag.

 

Yea i don't think its the VIS motor I just know that the arm did not move as supposed to according to Tech Buliten for VIS motor. the arm just moves where ever i put it. no spring acction to it.


Do I need to replace the Upper air intake?

 

is it noisy. if not then don't bother but check all the codes. not just those.

 

it makes a ticking noise, at least i think its coming from there.
