Engine died while driving - oil light came on

I would say you need to investigate replacing your cam sensor if you got that code and are experiencing shutdowns.

 

Was it this bad?

 

The engine won't run if the various cam/crank position sensors aren't communicating. P0345 is an open or short in the bank 2 (driver's side) VVT sensor circuit. You can unplug the sensor and do a basic voltage check, but if that doesn't show an exceedance, you will need a lab scope to diagnose it completely.

 

No. It is a variable reluctor that reads the magnetic signature oe the steel vanes passing by on the cam wheel. While a large collection of ferrous shavings stuck to the sensor can cause issues, nothing non ferrous like oil or coolant can mess it up.

 

If the CEL was a P0345, then replacing the CPS with an OEM one would be the route I would take.

 

Everything looks different and worse AFTER a problem occurs.
You need a scan tool.
