Chevy & GMC Vans

When replacing the Crankshaft or Camshaft position sensors do you need to do a RE-LEARN procedure? There are some youtube videos that say so on other vehicles but don't spell it out for ours. What do you think?



Thanks in advance,

Andy R

it's in the service manual link I sent you before
