My engine light came on yesterday so I had Autozone hook up their gadget to it and it said "p1682 driver 5 line 2". The guy told me he did not have the slightest idea what that meant and now my car wont even turn over (lights come on but engine does not even click when i turn the key). Anyone know what this code means? I know the codes can be specific...my car is an 06 Buick Rainier 8cyl 5.3l.
