P0522 and P0335 codes 07 Hemi

Have a 2007 Chrysler Aspen 5.7 Hemi that as we were leaving to head out on vacation and it threw two codes this morning. P0522 low oil pressure switch and P0335 crankshaft position sensor. We are on vacation and it has performed flawlessly thus far. This morning extended crank time. Will get a rose to O Reilly to get oil pressure switch and crankshaft switch. Anything else it could be? Battery is good and charging good.

Don't know about Aspen, but g3 ram they share the same wiring harness. Cam sensor and crank sensors often diagnose the same. But a crank sensor usually gives a stumble or won't run. All use a common 5vdc sensor voltage. Physical location of cam sensor and oil pressure sensor is near one another. I would check the wiring for damage and the electrical plugs. Maybe shoot some cleaner on them if they are dirty. Good luck.

Also forgot to mention that it has the little lightning bolt flashing in the dash. My neighbor has a nice new Snap On diagnostic scanner and he saying that the throttle body isn’t working at all. Pulled all kinds of codes up with his scanner. Accelerator pedal code, TPS code, low circuit voltage. Looking at changing the throttle body out.

Ok. So I replaced the throttle body with a brand new Mopar unit. Didn’t change anything. Also changed the crankshaft position sensor. Still the same. I suppose I’m hunting one of those electrical issues. I seem to be getting my 5 volts to run the sensors but at a loss. Any advice or help would be greatly appreciated.
