Ignition on, engine not running.
Measure the voltage between the 5-volt supply and return circuits of the Fuel pressure sensor harness connector.
Is the voltage between 4.5 and 5.5 volts? Yes
Reconnect the disconnected Fuel Pressure Sensor harness connector.
Clear the code
While monitoring scan tool, disconnect the Fuel Pressure sensor harness connector.
Does the DTC P0193 set? Yes
Replace the fuel pressure sensor
