P1391 Code - 99 Jeep Grand Cherokee

P1391 Code - 99 Jeep Grand Cherokee


I have a 99 Jeep Grand Cherokee and the engine light and airbag light are staying on and its throwing the code
P1391- Camshaft or crankshaft signal sensor intermittent. Before this it was throwing that code & P1698- PCM Fault No CCP. That one is no longer coming up. The airbag keeps dinging, what could it be? It runs and drives good, havent had any issues with it. What else should I look for? The motor was just put in, its out of an 04' JGC. I just need to get these 2 lights off. Any help would be great! Thanks
