I have a 2006 Trailblazer LS 6 Cylinder.
I am getting a P1516 code after replacing the ignition switch.
Many variables with this code. Try and clean throttle body?
Battery might be a bit low but starts fine. Slightly rough idle.
Checked all connections and nothing loose or obvious.
Any ideas?

On another forum someone said to disconnect the battery and put it on a charge overnight. The purpose was to do a reset as well as charge the battery. It worked. A low battery can result in a false P1516.
