ERROR CODES - please help

[TMCNORWAY]

My truck keeps throwing the following codes on my SCT.
It hasn't been driven, I just started it and left it running for 10
minutes at a time, reving to about 4000 now and then.

Just checking for leaks and issues after it sitting where it is for 9 months.

The codes.

P0340 Camshaft Position (CMP) Sensor Circuit
P1391 Wheel Speed Sensor 1 - G - Sensor Circuit Performance

It wasn't throwing these codes before, only now after it has been sitting
for 9 months. Are any of these two serious?

Thanks

Mark

Been doing some research, there are simple explanations,

Running at idle for a long period, to much fuel usage and high reving at stand still will simply
throw code P0340. - which all I have been doing recently.

And P1391 is quite expalainable too. The brakes have just litterally been frozen at
-30 for several months, and there was much rust around the disks etc.
