P062F Code: Internal Control Module EEPROM Error

Your vehicle is equipped with a variety of computers, referred to as control modules. Each module has temporary memory and permanent memory.

The electronically erasable read-only memory (EEPROM) is a type of permanent memory that can be reprogrammed using the correct equipment and software.  If the PCM (or one of the car’s other modules) detects an internal EEPROM failure, on-board diagnostics will log a P062F code.

What Does the P062F Code Mean?

Diagnostic trouble code (DTC) P062F stands for “Internal Control Module EEPROM Error.”

All vehicles equipped with the second generation of on-board diagnostics (OBD-II) have EEPROMs. The EEPROM is a chip that can be reprogrammed using a scan tool and the appropriate software.

If the PCM detects an issue with the EEPROM or any problem between the other on-board controllers indicating an internal EEPROM error, the computer will log a P062F trouble code.

You can learn more about computers in cars in our discussion about the ECM/PCM’s Random Access Memory (RAM).

Note: The definition of code P062F can differ depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P062F Code?

• Defective PCM or other control module
• Insufficient control module power supply or ground
• Programming error

What are the Common Symptoms of the P062F Code?

• Engine stalling or shutdown
• One or more computer outputs might not work
• Vehicle won’t start
• Transmission issues
• No start condition

How to Diagnose the P062F Code

A DTC P062F is a generic powertrain code that can be logged in various makes and models. However, keep in mind that the steps for diagnosis and repair can vary depending on your vehicle’s specifications.

If you’re not familiar with the process of diagnosing trouble codes by yourself, it’s a good idea to let a certified mechanic handle the task. This ensures that all steps and protocols are followed correctly. But if you have sufficient knowledge of what the process involves, then you can go ahead and do it yourself.

To help you out, here are some videos that can give you an idea of what the process might involve:

How to Fix the P062F Code

Attempting to diagnose and fix a P062F code can be confusing and frustrating if you’re not used to doing it on your own. Note that you can always bring your vehicle to a certified  mechanic to resolve this trouble code if you’re not confident with your DIY skills.

But if you’re a seasoned DIYer who knows how to work your way around DTCs, make sure you’re consulting the right manuals before proceeding with diagnosing and repairing your vehicle. Guides like those from Chilton and an ALLDATA subscription contain vehicle-specific repair information, so you might want to check those out before your start.
