P0192 - Fuel Rail Pressure Sensor A Circuit Low
Description: The comprehensive component monitor (CCM) monitors the fuel rail pressure (FRP) sensor circuit to the powertrain control module (PCM) for low voltage. The test fails if the voltage falls below a calibrated limit for a calibrated amount of time during testing.
Possible Causes:
FRP signal short to SIG RTN or PWR GND
Damaged FRP sensor
Diagnostic Aids:
A FRP parameter identification (PID) value during ignition ON, engine OFF or ignition ON, engine running less than 0.3 volt indicates a concern is present.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DD .
Removal and Installation
WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.
Release the fuel system pressure. For additional information, refer to Section 310-00 .
Disconnect the battery ground cable. For additional information, refer to Section 414-01 .
Remove the intake manifold. For additional information, refer to Section 303-01B .
Disconnect the Fuel Rail Pressure (FRP) sensor electrical connector.
Remove the FRP sensor.
To install, tighten to 33 Nm (24 lb-ft).
To install, reverse the removal procedure.
