Got my engine codes

[Got Milk?]

I've got codes: P1693, P0253, and P0341. All of these codes are with the redline unhooked. So whats all of them mean? Thanks.

P0253 (M) - Fuel Injection Pump Fuel Valve Open Circuit
Problem sensed with fuel circuit internal to fuel injection pump.

P0341 (M) - Camshaft Position (CMP) Sensor Signal
Problem with voltage signal from CMP.

P1693 - Companion code set because of the other codes

I have a new (CMP) sensor, But does the other codes mean the pump is taking a chit? Or is somthing eles a factor?
