What is P0625?

The diagnostic trouble code (DTC) P0625 indicates a malfunction in the fuel pump control module. This code is commonly found in vehicles like Ford F-Series trucks, Chevrolet Silverados, and Honda Accords. When the Engine Control Module (ECM) detects an issue with the fuel pump control circuit, it triggers this code. The fuel pump control module regulates the electric fuel pump's operation to ensure optimal fuel delivery to the engine. If there's a malfunction, it can lead to insufficient fuel supply, causing performance issues such as engine stalling, poor acceleration, or even complete engine failure. Additionally, you may experience a decrease in fuel efficiency and increased emissions. Ignoring this code can lead to more serious engine problems and expensive repairs down the line. Therefore, it's essential to address the P0625 code promptly. In some cases, this issue may be accompanied by other codes that can provide additional insight into the problem, so using an OBD2 scanner like the GeekOBD APP can help identify multiple issues at once.

Symptoms

Common symptoms when P0625 is present:

  • Check engine light stays on constantly, indicating a persistent issue with the fuel pump control.
  • Engine hesitates during acceleration, which can lead to a frustrating driving experience and potential safety hazards.
  • Fuel economy decreased by 10-15%, meaning you may be filling up more often than usual.
  • Difficulty starting the engine, especially after the vehicle has been sitting for a while.
  • Unusual noises from the fuel pump area, such as whirring or grinding, which may indicate wear or malfunction.

Possible Causes

Most common causes of P0625 (ordered by frequency):

  1. The most common cause of P0625 is a faulty fuel pump control module, occurring in about 60% of cases. This can happen due to electrical failures or wear and tear over time.
  2. A corroded or damaged wiring harness is the second most common cause, leading to poor electrical connections that prevent proper module operation.
  3. Faulty fuel pump is another potential cause, usually stemming from age or contamination in the fuel system. Regular maintenance and fuel filter changes can help prevent this.
  4. Less common but serious causes include issues within the Engine Control Module (ECM), which can affect the overall performance of the vehicle.
  5. A rare cause could be an issue with the vehicle’s security system, which may inadvertently disable the fuel pump control module.
