DTC P0192: Fuel Rail Pressure (FRP) Sensor Circuit Low 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.

P0192 - FUEL RAIL PRESSURE (FRP) SENSOR CIRCUIT LOW INPUT

Description:	The comprehensive component monitor (CCM) monitors the FRP sensor circuit to the powertrain control module (PCM) for low voltage. If voltage falls below a calibrated limit for a calibrated amount of time during testing, the test fails.
Possible Causes:	FRP signal shorted to SIG RTN or PWR GND Damaged FRP sensor
Diagnostic Aids:	A FRP PID value during the key on engine off (KOEO) or key on engine running (KOER) less than 0.3 volt indicates a hard fault.
Application	Key On Engine Off	Key On Engine Running	Continuous Memory
