P1697 A companion DTC was set in both the ECM and PCM.

P0522 Engine Oil Pressure/Switch Low Voltage.

P0230 Fuel Pump Primary Circuit Malfunction.

The P0230 code sets when the ecm sees a voltage out of range on the ground circuit that terminates at the ECM. The lift pump can fail in two common fashions. Loss of psi/volume which is a mechanical prob that won't have a code, or the electrical part of it (motor) that will show up as an out of range voltage. Could be wiring (or connection at pump or if its been unpluged), but most of the time the motor in the pump is giving up.

Just disconnect your battery for a few minutes and it will clear the codes. Nothing to it. As far as the P1693, I would just see if it comes back. If it does, start figuring it out then.
