Multiecuscan

Good morning

WHen establishing connection with my ECU I have noticed that the ECU Programming date show 00/00/0000. Does this mean the ECUs mapping is gone.
I am receiving a P0336 (Crankshaft Position sensor "A" Circuit Range/Performance) error code. I have replaced the sensor and tested all cables and connectors related to the sensor.
The vehicle starts but idles rough and wont rev above 2000 RPM.

The vehicle is a 2006 Alfa 159 2.2 JTS

Any advice and feedback would be appreciated.

Regards

Leigh

Did replacement of the sensor clear the P0336?
If not, there must be some other fault causing the error.
What, if any, other errors is MES reporting?

I can't comment on the significance of the strange date.
