What does code P0627 mean?
When Error Code P0627 appears, that means there’s a problem detected in the fuel pump “A” control circuit. This is usually caused by damaged connectors/wires within the circuit or the CAN (Controller Area Network) bus.
What does fuel pump a control circuit open mean?
OBD-II Code P0627 is defined as a Fuel Pump “A” Control Circuit/Open. The Fuel Pump enables the transfer of fuel from the tank to the fuel injectors. If the engine control module (PCM) detects the fuel pump is not operating properly, the PCM will set code P0627.
How do I fix my P0230 code?
What repairs can fix the P0230 code?
- Repairing or replacing the fuel pump fuse or fusible link, and replacing the fuel pump.
- Replacing the fuel pump relay.
- Replacing the fuel pump only.
Where is the fuel pump control module?
The module is typically installed on or very close to the fuel pump, and in the early years of the component’s use, this practice led to a design fault. Manufacturers, including Ford, initially placed the module inside the vehicle immediately above the fuel pump, typically just beneath the floor pan.
What causes a P0230 code?
Code P0230 is triggered by low voltage in the main power circuit of the fuel pump relay. The ECM monitors this voltage to see if it falls below a specified voltage.
How do I know if my fuel pump control module is bad?
Usually a bad or failing fuel pump relay will produce a few symptoms that can alert the driver of the issues.
- Engine stalls. One of the first symptoms of an issue with the fuel pump relay is an engine that suddenly stalls.
- Engine does not start.
- No noise from the fuel pump.
Does the fuel pump control module?

- Push the button on the inertial switch; it should be clearly marked as the fuel pump reset, and may be in a contrasting color to the case.
What does the p0627 code on a fuel pump mean?
Nonetheless, in both designs, the PCM will set code P0627, and illuminate a warning light when an open circuit condition is detected in the fuel pumps’ control circuit. The image below shows a simplified schematic of a typical return-less fuel injection system.
What does the p0627 code on a PCM mean?
What the P0627 code means If the PCM has stored this code, it means that when the ignition switch is turned on, the ECM attempted to run the in-tank fuel pump or the fuel pump relay, but a malfunction occurred.
