P0192: Fuel Rail Pressure (FRP) Sensor Circuit Low Input

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. 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 PCM for low voltage. If voltage falls below a calibrated limit and a calibrated amount of time during testing, the test fails.
Possible Causes:	FRP signal shorted to SIG RTN or PWR GND. FRP signal open (NG only). Low fuel pressure (NG only). Damaged FRP sensor. Damaged PCM.
Diagnostic Aids:	An FRP PID value during KOER or KOEO less than 0.3 volt for gasoline or 0.5 volt for natural gas vehicles (NG) indicates a hard fault.
