My check engine light came on yesterday so I hooked an OBD II up to my 2011 Grand Cherokee and the codes P054A and P054C came up. The explanation of the codes was; Cold Start "B" Camshaft Position Timing Over-Advanced Bank 1 and Cold Start "B" Camshaft Position Timing Over-Advanced Bank 2. Could someone please elaborate the explanation of this for me, im not too mechanically savy. Also, should I just go ahead and clear the codes and see if the problem arises again or should I bring my Jeep to a service center?
