So I thought I would pose a question today, since this is something I’ve been dealing with all day. What exactly does the offset key do in regards to timing? I’ve searched the inter webs and I can’t find anything more than a generic, “It works with timing the pump”, or “The key has to be calibrated to each pump”. What does it do? Is there a hidden ignition pickup or sensor in the gear cover that reads the key? Reason I’m asking is because my key is crushed (My F-up). I think at some point between 1998.5-2002, Dodge took either the crank or cam sensor out of the truck when built. I have an 01, and it only has one of those sensors. I’m wondering if the key is irrelevant on those later trucks not equipped with the cam/crank sensor (still can’t remember which one I have). Any clarity on what the hell that key affects regarding timing would be much appreciated.
