You will also want to check chassis and engine ground junctions. If there is no voltage (and/or ground) on the fuel pump control circuit (and all fuses and relays appear to be functioning properly) an inspection of controller related wiring and harnesses is in order. If the vehicle is equipped with a fuel pump voltage shutoff switch, test it to make sure that it has not been activated or is defective. If not check system fuses and relays and replace defective parts as required.

HOW TO DIAGNOSE A BAD FUEL PUMP MODULE ON A 2007 F150 CODE

Use your source of vehicle information to obtain connector face views, connector pin-out charts, component locators, wiring diagrams, and diagnostic flow charts related to the code and vehicle in question.Ĭheck to see if there is battery voltage on the fuel pump control circuit by using the appropriate wiring diagram and your DVOM. If the code is reset, continue with your diagnosis.

The condition, which caused the P064A to be stored, may need to worsen before an accurate diagnosis can be reached. If the PCM enters readiness mode, the code is intermittent and will be more difficult to diagnose. After recording all pertinent information, clear the codes and test drive the vehicle (if possible) until the code is reset or the PCM enters readiness mode. You will want to write this information down, just in case the code proves to be an intermittent one. If you find the appropriate TSB, it may yield helpful diagnostic information.īegin by connecting the scanner to the vehicle diagnostic port and retrieving all stored codes and freeze frame data. What are some P064A troubleshooting steps?Ī diagnostic scanner, a digital volt/ohmmeter (DVOM), and a source of reliable vehicle information will be required to diagnose a code P064A.Ĭonsult your vehicle information source for technical service bulletins (TSB) that replicate the code stored, vehicle (year, make, model, and engine), and symptoms exhibited.

Open or shorted fuel pump control circuit.

Bad or tripped fuel pump voltage shutoff switch.

Open fuel pump control module voltage supply circuit.

What are some of the common causes of the code? Symptoms of a P064A trouble code may include: What are some of the symptoms of the code? A stored code P064A could result in a no-start condition. If a problem is detected in monitoring the fuel pump control module, a code P064A will be stored and a malfunction indicator lamp (MIL) may be illuminated.įuel pump control module codes should be taken seriously.

HOW TO DIAGNOSE A BAD FUEL PUMP MODULE ON A 2007 F150 SERIAL

By performing internal controller self-tests, the PCM can monitor serial data that is carried over the controller area network (CAN) to ensure that on-board controllers are interfacing properly. It is most often located inside the fuel tank.Įach time the ignition is turned on and the PCM is energized, multiple controller self-tests are performed. The fuel pump provides pressurized fuel for the fuel injection system. In most cases, the fuel pump controller is integrated into the PCM but it may also be a stand-alone module. The fuel pump control module is responsible for supply and regulation of voltage to the fuel pump relay and the fuel pump. Although generic, the exact repair steps may vary depending on year, make, model, and powertrain configuration.Ī stored code P064A means that the powertrain control module (PCM) has detected a malfunction in the fuel pump control module.

That may include but is not limited to vehicles from Chrysler, Ford, General Motors, Mercedes-Benz, etc. This is a generic diagnostic trouble code (DTC) and applies to many OBD-II vehicles (1996-newer). Fuel Pump Control Module What does that mean?
