DTC P0193: Fuel Rail Pressure (FRP) Sensor Circuit High Input

WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2005 Mercury Sable, 2005 Mercury Mountaineer, 2005 Mercury Monterey, 2005 Mercury Montego, and 2005 Mercury Mariner. However, it is still accessible from the selected car via links, so may be relevant.

P0193 - FUEL RAIL PRESSURE (FRP) SENSOR CIRCUIT HIGH INPUT

Description:	The comprehensive component monitor (CCM) monitors the FRP sensor circuit to the powertrain control module (PCM) for high voltage. If voltage exceeds a calibrated limit for a calibrated amount of time during testing, the test fails.
Possible Causes:	FRP signal shorted to VREF or VPWR FRP signal open Damaged FRP sensor
Diagnostic Aids:	An FRP signal high condition can be caused by any number of conditions, including a short on FRP signal to VREF, a more positive voltage level, an open FRP signal or signal return. The FRP signal line is pulled up by the PCM and VREF at the sensor, and down by the sensor through SIGRTN.
