What engine and model? Sure code is correct?

Hello, thank you for a very quick response. Here are more details about my Focus and problems. I have Ford Focus II, engine 2.0 TDCi. When I was driving car, it shaked twice like the ESP went on and then I got on display two errors. First was System Engine Fault and the second was ESP System Fault. Engine turned off by it self. I turned the car key to the off position and then back to turn on. The car started with no problem. I managed to get home. At home I connected to OBD controller and check for errors with my android phone. I've got this errors: -U2023 - Network
-U2196 - Network
-P0336 - Crankshaft Position Sensor Range/Performance
Car is now running normally, well in my garage : )
So is there really "dead" sensor or is it something else?

An intermittent problem which could mean a loose connection somewhere and is not going to be easy to diagnose for the U-codes. Try clearing the codes and see if they reappear.

OK, I will try that and report.

Mod doesn't show a p0336. That was probably what docfixit was asking? Info on the u-codes says to fix all other codes first.
