P0727

I recently completed crankshaft sensor and camshaft sensor replacement on a 2003 sorento. I have no cel but the system is showing a P0727 code. The vehicle runs well. I am at a lost for what to check on this next. The passenger side at feet level is dry and all the connections are good the Ecm connectors all look good. Any help would be appreciated.

Not sure if it applies to your vehicle, but there have been reports way back on other forums about water leaks from the radiator expansion tank due to a split, that wets a multi way connector under the tank. This leads to all sorts of strange error codes and malfunctions.
Or was that the windshield washer tank? Pay to check under both.

+1 on checking the connector for a coolant leak. If that isn't a problem maybe the P0727 code is just leftover from when you were working on the CPS and CKP. The car is running well and there is no CEL so I would clear the code and see if it comes back.
Welcome to the forum! Good luck!
