p1693 is a companion code, take it to AutoZone or somewhere like that and have them run a scan on it.
p0216 is injection pump failure.
Looks like a new VP in your near future.
If you're still under warranty its free, take it to the dealership and tell them to fix it, if not there are a few people on TDR that can probably help you out with getting one reasonable. Sorry.
