Pinpoint Test Me: Fuel Pump Control
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Contact with exposed fuel injector wiring, if energized, may result in electric shock. Use care when working on or around energized fuel injector wiring. Fuel injector wiring supplies high voltage to operate the fuel injectors. Failure to follow this instruction may result in serious personal injury.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
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 the output driver signal for the FVCV circuit moves outside the minimum or maximum limit for the commanded state. A concern with the fuel volume control valve or FVCV circuit may cause an engine crank no start condition. This DTC indicates an intermittent concern if the engine starts and DTC P0001 is present. |
| PCM P0002:00 | Fuel Volume Regulator "A" Control Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects output driver signal for the FVCV circuit moves outside the minimum or maximum limit for the commanded state. This DTC sets when the temperature of PCM power stage driver is greater than 170 deg.C (338 deg.F). |
| PCM P0003:00 | Fuel Volume Regulator "A" Control Circuit Low: No Sub Type Information | Sets when the PCM detects the output driver signal for the FVCV circuit moves outside the minimum or maximum limit for the commanded state. A concern with the fuel volume control valve or FVCV circuit may cause an engine crank no start condition. This DTC indicates an intermittent concern if the engine starts and DTC P0001 is present. |
| PCM P0004:00 | Fuel Volume Regulator "A" Control Circuit High: No Sub Type Information | Sets when the PCM detects the output driver signal for the FVCV circuit moves outside the minimum or maximum limit for the commanded state. A concern with the fuel volume control valve or FVCV circuit may cause an engine crank no start condition. This DTC indicates an intermittent concern if the engine starts and DTC P0001 is present. |
| PCM P0089:00 | Fuel Pressure Regulator "A" Performance: No Sub Type Information | Sets when the PCM detects the output driver signal for the FPCV circuit moves outside the minimum or maximum limit for the commanded state or when the measured fuel rail pressure exceeds commanded fuel rail pressure by a calibrated limit. The presence of this DTC may indicate the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle until the system warning message has cleared from the IPC message center. |
| PCM P0090:00 | Fuel Pressure Regulator "A" Control Circuit/Open: No Sub Type Information | Sets when the PCM detects the output driver signal for the FPCV circuit moves outside the minimum or maximum limit for the commanded state. This DTC sets when the PCM detects an open from the FPCV circuit. |
| PCM P0091:00 | Fuel Pressure Regulator "A" Control Circuit Low: No Sub Type Information | Sets when the PCM detects the output driver signal for the FPCV circuit moves outside the minimum or maximum limit for the commanded state. The presence of this DTC may indicate the vehicle is operating in derate mode and may experience a loss of power. After repair, the vehicle may still display a system warning message. Drive the vehicle until the system warning message has cleared from the IPC message center. This DTC sets when there is a short to ground on the FPCV circuit. |
| PCM P0092:00 | Fuel Pressure Regulator "A" Control Circuit High: No Sub Type Information | Sets when the PCM detects the output driver signal for the FPCV circuit moves outside the minimum or maximum limit for the commanded state. This DTC sets when the PCM detects a short to voltage from the FPCV circuit. |
