P1446 is a vent control valve code. The valve that attaches to the vaor cannister under the truck. There is a bulletin for this that includes repalcing the valve and installing a filter kit.
P1615 is a Nats malfunction code. could be voltage, unprogramed key, remote start issue, etc etc etc.....

With the price of gas here, $1.20+ /L, perhaps it's not such a bad thing..... JK.

I will have to get my 1500KM away dealer to agree to put it into a local shop to look at.
