P0045 is a turbo solenoid circuit code. Disconnect the solenoid and put a test lamp across the solenoid connector when the engine coolant temp is colder than 65C, then start the engine and let it warm up to 74C. When the engine coolant reaches approximately 74C the ECM will initiate a TC Learn and the test lamp will flash ON and OFF.

The P0193 code indicates that the engine control unit gets a too high signal from the fuel rail pressure sensor.

Dec 31, 2016 · No info on P0089, but here is P0090: Circuit/System Description. High pressure fuel is regulated by the fuel rail pressure (FRP) regulator mounted on the fuel injection pump. The FRP regulator is controlled by the engine control module (ECM). The FRP regulator has a solenoid supply voltage circuit and solenoid control circuit. A stored code P0090 means that the powertrain control module (PCM) has detected an open control circuit in the electronic fuel pressure regulator (designated 1). This designation is used in systems that incorporate multiple electronic fuel pressure regulators. This type of designation may refer to the engine bank but not exclusively. P0090 is fuel pressure regulator related, not the rail pressure sensor. You either have a sticky FPR, a bad coil in the FPR or no power to the FPR. you need 5v to the FPR for it to be controlled.
