P0633 and P0336
My check engine light came on this morning and my truck is giving me these 2 codes. the P0633 i looked up and it says the "SKIM Key not programmed in PCM" and the P0336 says "Crankshaft Position Sensor Performance." Does anybody know how to fix or what these mean? my truck is still running fine but i don't like the fact that the check engine light came on and it worries me.
