Hello,

This could be a problem with your vehicle's Camshaft Position Sensor[CMP] , which your vehicle's Power-train Control Module[PCM] uses to fire the ignition coils and synchronize the fuel injectors to fire them. When a camshaft sensor starts to fail, the coils that it uses internally get hot, expand, and start to short out. In the diagrams down below I have included the instructions for the removal and installation of the CMP for your vehicle from the vehicle manufacturer. Please go through this guide and get back to us with how everything turns out.

Thanks,
Alex
