Hello, we recently purchased a used 2011 Caravan, and we occasionally will get a Check Engine Light, and when I read out the code, I get a "P000D" message which is described as "B Camshaft Position Slow Response".

The code will lock for a couple of days and then go away. It seems to pop up about once a month or so. When it does appear, I think it is soon after starting the engine so perhaps, it's related to a cold engine.

Nothing seems to be out of sort with the engine or with the transmission. It seems to be running smooth.

Some notes out on the web mention a software update that may be related, does anyone know how to check the software version of the firmware on the vehicle?

Thanks,

-Steve
