Error Code P062A: What It Means & What To Do?

<<See All OBD Codes

Every vehicle has a fuel pump, the function of it is to transfer fuel from the tank to the fuel injectors. If the PCM (Powertrain Control Module) starts to detects a malfunction in the fuel pump, it will set OBD code P062A

The fuel pump holds a significant position in a fuel driven vehicle. It is primarily responsible for delivering fuel to the engine. The control circuit turns the pump on and off as per the need of the operator. Before initiating the diagnosis process, be mindful that an open within the circuit is also responsible for this code. Subject to the model of the vehicle and model this code may get activated after several drive cycles. At times it may also be an immediate reaction to the ECM recognizing this fault. The P062A code is set when there is an open within in the control circuit. Hence, it is important to be mindful of this before initiating diagnosis of the OBD error.

What causes this problem with the Fuel Pump "A" Control Circuit Range/Performance?

• Faulty fuel pump
• Damaged ground wire present in the control module
• Ground strap unattached in the control module
• CAN bus wiring damaged, corroded open or shorted
• CAN bus faulty
• Chafing or broken circuits caused by unsecured harnesses and wires
• Unusually high resistance in circuit like melted/corroded connectors, internal wire corrosion etc.

Here are some steps which should follow for diagnosing the problem that triggered a P062A code to be stored. Get hold of your specific vehicles Technical Service Bulletins (TSB), this can help save a lot of time in diagnosis. Now that you have it handy, follow these simple steps:

Step 1 - Start off by procuring a OBD-II scanner and immediately scan and test each module, this will give you a good idea of your vehicle and its modules’ overall condition. Then move on to visually inspecting the connectors and wiring. If you note any damage you can simply try repairing, if not opt for replacement. Typically, these are located under the fuel tank of vehicles, and are hence, subjected to road debris and other elements. So, ensure you check them thoroughly.

Step 2 - When examining any component that has its own module, pay special attention to the attached ground circuits. For this, you can use a separate battery ground. sometimes, you may also do this easily busing an auxiliary ground cable, if that rectifies your problem but then comes back when the OEM ground is used, then it would signify that your ground cable is the culprit and requires a repair or replacement. You have to inspect that there are no corroded connections, terminal, pins etc. at the ground, because these could cause the resistance of the circuit. If you notice a green ring around the connector which is attached to the positive battery terminal, this is a sign of excessive corrosion. To resolve this, remove the terminal and clean all the contact point, connector face and the terminal post/stud thoroughly. You may have to use separate cleaning products for this.

Step 3 - An open circuit could very well be a reason for the OBD code P062A, so it only makes sense to identify the circuit using an electrical wiring diagram from your service manual. Upon identification, trace the individual fuel pump A control wire individually, and see if there are any visually obvious breaks in this wire. Depending on what you discover, repair by either soldering the wire, or using butt connectors with heat shrink to insulate it from the elements. You can measure the resistance now, using a multimeter and pinpoint the location of short/open circuit. It is highly recommended to use a power probe style tool, if a fault is somewhere inside the entire circuit.
