P2624 code definition

The P2624 Trouble Code indicates that there is an issue with the fuel pump B control circulation being high.

What the P2624 code means

If the P2624 code is stored in the vehicle, it means that there is an issue with the fuel pump B control circuit. Most of the time, the powertrain control module will detect this fault. However, there are other modules that can detect the problem as well, including the alternative fuel control module, body control module, instrument panel control module, alternative fuel control module, fuel injection control module, turbo control module, the anti-theft module, cruise control module, antilock brake control module, traction control module, proximity alert module, and the climate control module.

What causes the P2624 code?

The following are the most common causes of the P2624 code:

  • Defective fuel pump
  • Defective fuel relay
  • Open, shorted, or corroded wiring
  • Open, shorted, or corroded electrical connectors
  • Defective CAN bus
  • Broken ground wire
  • A loosened control module ground strap

What are the symptoms of the P2624 code?

In addition to having a stored code, there can be a number of other symptoms when the code is present. The fuel cap malfunction light might be on, and the Check Engine Light could come on as well. Other than these issues, there aren’t any other major problems. Unless there are other issues with the vehicle, the driver shouldn’t have any drivability issues. However, this does not mean they should ignore the problem and wait to get the vehicle fixed. It is always important to take care of these types of issues as soon as possible.

How does a mechanic diagnose the P2624 code?

The mechanic will start by connecting his or her OBD-II scanner to the vehicle’s onboard computer. The computer has gathered data about the vehicle, and the scanner can then access this data. It provides the mechanic with the information needed to understand what is wrong with the vehicle and to help them get a better understanding of what they need to do in order to make the repairs. They will also reset the codes and then test the vehicle. They do this to see if the code being stored was simply an error or if there is truly something wrong with the vehicle. If the code comes back, they will then continue to diagnose the vehicle to find the actual issue.

Common mistakes when diagnosing the P2624 code

Many times, the codes that are stored are misdiagnosed as being a problem with communication within the vehicle. The technician repairs those issues, but never gets to the root of the actual problem. This leads to a repair that doesn’t work. It is important that the mechanic follow through with a full diagnosis.

How serious is the P2624 code?

Even though the only issue that you can see might be lights on your instrument panel, that doesn’t mean you should ignore it. You may not have any issues with drivability of the vehicle, but you still need to have the codes checked out and repaired.

What repairs can fix the P2624 code?

The mechanic can make the following types of repairs to fix the P2624 code:

Additional comments for consideration regarding the P2624 code

The P2624 code might seem very minor since there are no issues with driving the vehicle. However, it is not something that you want to ignore. You should still take the vehicle to a mechanic who can diagnose the problems with the car or truck and make the needed repairs. It will help to keep your vehicle in good running condition.
