What does p0627 fuel pump control circuit mean?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. If the P0627 code appears, it means that a problem has been found in the fuel pump “A” control circuit. Typically, it is brought on by damaged wires/connectors within the circuit or the Controller Area Network (CAN) bus.
What are the codes for a fuel pump?
Related fuel pump A control circuit codes include: P0627 Fuel Pump “A” Control Circuit /Open. P0628 Fuel Pump “A” Control Circuit Low. P0629 Fuel Pump “A” Control Circuit High. P062A Fuel Pump “A” Control Circuit Range/Performance.
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.
Why is my fuel pump control circuit open?
NOTE #2: If codes relating to open system voltages are present, there is a more than even chance that the open system voltage is the root cause of P0627, which means that if such codes are present, they MUST be resolved before any attempt is made to diagnose P0627 or low fuel pressure related codes.

How much does it cost to repair Ford p0627 code?
The cost of diagnosing the P0627 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
How does the fuel pump control module work?
The fuel pump control module monitors the fuel pump module and secondary circuits for a concern. If the fuel pump control module detects a concern with the fuel pump module or secondary circuits, the fuel pump control module sends an 80% duty cycle signal on the fuel pump monitor (FPM) circuit to report the concern to the PCM.
What causes a fuel pump control circuit to chafe?
Causes for this code may include: Issues with the fuel pump itself Severed or damaged ground wire in the device’s control module Unattached ground strap in the control module Open, shorted, or corroded wiring in the CAN bus Unsecured harnesses and wires causing a chafe or broken circuit

What happens when the fuel pump goes out in a Jeep Grand Cherokee?
There are physical signs that you can feel when your Grand Cherokee’s fuel pump is going out. Before taking anything apart, check to see if your engine’s computer has any trouble codes saved in it. The engine may throw a P0087 trouble code. This trouble code detects that the fuel rail/system pressure is too low.
Can a Jeep Grand Cherokee Run without gas?
Without gas your Grand Cherokee will not run at all. With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all. In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail (s).
