P062B OBD Error Code: Problem & Solutions

<<See All OBD Codes

In vehicles, the PCM is responsible for managing the fuel injector operation. If and when the PCM loses this control over the fuel injector due to an internal fault in the PCM, the error code P062B is set.

In simple words, an OBD error code P062B signifies that the PCM has detected an internal performance error with regards to the fuel injection system. There may be other controllers also who may detect this internal PCM performance error (fuel injection control system) and cause this code to be stored.

What causes this problem with the internal control module fuel injector control performance?

• Open or shorted circuit or connectors in the CAN harness
• Insufficient control module ground
• Defective fuel injector/s
• Defective controller or programming error
• Open or shorted circuits between the fuel injector and the PCM

1. CAN Circuit - Circuits need to be functioning smoothly, repair or replace them easily.
2. CAN Connectors - Connectors need to be working well, if you can repair them, then good.
3. Fuel Injector/s - Need to be replaced as soon as repairing can’t sort their issues out. Order online and avail free shipping over orders of CAD $99.
4. PCM - Replace your PCM with only the best from Parts Avatar.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P062B here:

Common Symptoms

• Misfiring engine
• Extremely lean or rich exhaust
• Hesitation noted upon acceleration of vehicle
• Misfire codes are stored in the vehicle system

Here are some ways with the help of which you will be able to correct the OBD Code P062B

• Repair or replace the CAN harness,
• Repair the fuel injector or replace it
• Repair or replace the PCM

Getting the parts that need to be fixed sorted is very important to correct your error code. There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade Circuit, Connectors, fuel injector/s, PCM and a lot more for our precious customers.

If you want to easily diagnose this P0699 fault code, then all you have to do is to follow the steps Here are some steps which you should follow in order to diagnose this P062B fault code:

Diagnosing this code can be a challenge for even the professionals. An issue with reprogramming also is present, and so it’s necessary that reprogramming equipment is present.

• Before attempting to initiate diagnosis of P062B it is important to rectify any ECM/PCM power supply codes that are present. Any individual fuel injector or fuel injector circuit codes present must also be diagnosed and repaired.
• Procure a diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source. If you have a fuel injector node light, then that can be helpful too in testing fuel injector circuits. All the preliminary tests can now be performed, so that individual controllers can be deemed defective (if any).
• Now, connect the scanner to the vehicle diagnostic port and retrieve all stored codes. Freeze frame the data, make note of it in a safe place. You may need to refer it if the code is intermittent. Now, clear the codes and take your vehicle on a test-drive, keep going till the code is reset or till the PCM enters readiness mode. If the latter happens then it code is intermittent and hence be more challenging to diagnose. At times, the condition that has caused the code to set may have to worsen to be able to clearly diagnose it. In case the code was reset, continue on with the following lists of preliminary tests.
• Information is very significant in the diagnosis of OBD Code P062B. The TSB (Technical Service Bulletin) of your vehicle will prove to be extremely helpful in this case. Look through your TSB and see if the matching code is found for your exact vehicle, if you spot it then follow the diagnostic steps mentioned in it.

Common Mistakes When Diagnosing the P062B Code

In vehicles that are CAN- equipped, stored codes are typically a reaction a failure in communication between modules. Because of this misinterpretation happen and make us replace components that have no connection with the CAN itself.
