Dtc 1336 - Wtf?
) but today thie light lit up. Scanned it and its 1336, Crankshaft variation Position not learned. Now I did a little searching over the web and found some bits of info here and there that this code will set after fairly major changes. I've been driving on this PCM now for a few months and haven't changed anything else. Why would this code be thrown now? Do I really need to pay GM to attempt to take care of this? Its a swapped car so that might be a *real* PITA and I'm broke anyway. Anyway for me to fix it myself?Thanks guys.
if it was just a glitch it will clear its self after 3 drive cycles.
