Introduction

NOTICE: Do not apply battery voltage across the fuel injection pump circuits. Damage to the fuel volume regulator solenoid may result.

Normal Operation and Fault Conditions

Refer to the DTC Fault Trigger Conditions.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
PCM P0001:00	Fuel Volume Regulator 'A' Control Circuit/Open: No Sub Type Information	Sets when the PCM detects high or low voltage from the fuel volume regulator (FVR) and fuel volume regulator return (FVRRTN) circuits.
PCM P0003:00	Fuel Volume Regulator 'A' Control Circuit Low: No Sub Type Information	Sets when the PCM detects high or low voltage from the fuel volume regulator (FVR) and fuel volume regulator return (FVRRTN) circuits. A FVRRTN circuit short to ground may damage the solenoid coil. If P0001 is retrieved after a circuit repair, check the solenoid coil for an open circuit.
PCM P0004:00	Fuel Volume Regulator 'A' Control Circuit High: No Sub Type Information	Sets when the PCM detects high or low voltage from the fuel volume regulator (FVR) and fuel volume regulator return (FVRRTN) circuits.
PCM P0087:00	Fuel Rail/System Pressure - Too Low (Bank 1): No Sub Type Information	Sets when the PCM detects it is no longer capable of maintaining the fuel pressure within the calibrated parameters. The PCM regulates the fuel rail pressure by controlling the fuel volume regulator. Diagnose any FRP and FVR circuit Diagnostic Trouble Codes (DTCs) first.
PCM P0088:00	Fuel Rail/System Pressure - Too High (Bank 1): No Sub Type Information	Sets when the PCM detects it is no longer capable of maintaining the fuel pressure within the calibrated parameters. The PCM regulates the fuel rail pressure by controlling the fuel volume regulator.
PCM P00C6:00	Fuel Rail Pressure Too Low - Engine Cranking (Bank 1): No Sub Type Information	Sets when the PCM detects the high pressure fuel system cannot achieve the threshold within certain time and crankshaft rotation limits; the PCM attempts to start the engine at fuel pump assembly pressure. The high pressure fuel system must reach a minimum pressure threshold before the engine can be started. The high pressure fuel system must reach a minimum pressure threshold before the engine can be started. Diagnose any FRP and fuel volume regulator (FVR) circuit Diagnostic Trouble Codes (DTCs) first.
PCM P053F:00	Cold Start Fuel Pressure Performance Bank 1: No Sub Type Information	Sets when the PCM detects the fuel rail pressure falls outside a calibrated threshold limit for controlling split injection during a cold start. The PCM monitors fuel rail pressure to control split injection. Diagnose any FRP and fuel volume regulator (FVR) circuit Diagnostic Trouble Codes (DTCs) first. Various engine driveability symptoms, including no start, hard start, rough idle, and backfiring may occur as a result of this DTC setting. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs), particularly P0087, P0088, or P00C6. Freeze frame data is not applicable to the cold start emission reduction monitor. For additional information, refer to the Cold Start Emission Reduction Monitor description.
