A P062F code is a code that refers to an Internal Control Module EEPROM error. Because it affects the EEPROM, it affects all OBD-II vehicles. This makes it one of the most common errors in OBD-II vehicles.
A P062F code affects the EEPROM, which means that it affects all OBD-II vehicles. OBD-II compatibility will depend on where your vehicle was bought, when new, and the year it was manufactured. It is best to check with your manufacturer.
What Brands Will This Code Cover?
This code affects all OBD-II vehicles. This includes, but is not limited to, the following vehicles:
- Ford
- Honda
- Mazda
- Mercedes
- Volkswagen
- Toyota
- Nissan
- Cadillac
- Suzuki
More About The P062F Code
A P062F code means that there is an error in the EEPROM (Electrically Erasable Programmable Read-Only Memory). This is often detected by the PCM (Powertrain Control Module).
A control module, like the PCM, is a computer that controls your vehicle. There are multiple control modules inside one vehicle. They ensure that all parts of your vehicle are working as intended.
Because control modules are computers, they require memory, both temporary and permanent, to function. Temporary memory is removed as soon as the computer is powered down, while permanent memory is kept even after the computer is turned off. The EEPROM is used to store permanent memory. It can be found within the PCM as a bank of transistors.
When the vehicle is running, the PCM will run self-tests on the EEPROM to ensure that it is functioning properly. When the PCM or another module detects a fault in the EEPROM, it will log a P062F code. It may also log a P062F error if it notices a problem within other controllers that indicates an EEPROM error.

What Are the Symptoms of a P062F Code?
Symptoms of a P062F code include the following:
- Stalling or shutdown engine
- Cooling fan not working
- No start condition
- Car consuming more fuel than usual
What Are Some Causes of a P062F Code?
Causes of the P062F code include:
- Defective EEPROM
- Overheated PCM
- Faulty controller power relay
- Blown fuse
- Water damage
- Open or shorted circuits or connectors in the CAN harness
How Serious Is the P062F Code?
A P062F code is a serious code, as it can affect the drivability and safety of your vehicle. If it is not repaired, this code will lead to more serious issues like an engine stall or a no-start condition. For this reason.
Can I Still Drive with a P062F Code?
You can still drive with a P062F code. When detected early, a P062F code may not affect a car’s drivability. However, a P062F code will cause more serious symptoms when left unrepaired, which may eventually cause drivability issues.
How Easy Is It to Diagnose a P062F Code?
Because a P062F code is a general diagnostic trouble code, it can be hard to diagnose. It can be difficult to determine which controller is defective, and controllers may need to be reprogrammed.
Diagnosis will also depend on the make of your vehicle, so you will need to refer to the correct manual. If you’re not familiar with diagnosing trouble codes, then it’s best to employ professional help to do the job.
When diagnosing, you will need to retrieve stored codes and freeze frame data, then determine if the code is intermittent. Intermittent codes will be harder to diagnose.
How Difficult Is It to Inspect a P062F Code?
Inspection will depend on the make, model, and engine of your vehicle. Unless you are used to inspecting a P062F code, it is best to hire professional help. Doing this will ensure that you follow all protocols and prevent further damage.
A P062F code is difficult to inspect because of the amount of information you will need. Inspections will depend on the make, model, and year of manufacture of your vehicle. You will need to have connector face views, diagnostic flow charts, and wiring diagrams, among other information.
You will also need to check controller power supply fuses and relays and inspect the controller wiring and harnesses. You will also need to check the chassis and ending ground chassis.
You will also need to inspect for damage from water, heat, or collisions. These types of visual inspections are part of routine vehicle maintenance and can prevent errors like a P062F code in the future.
Need Additional Help with Your P062F Code?
Diagnosing and fixing a P062F code can be complicated and confusing. Even with the most trusted professionals, it can take a lot of time and effort to fix. However, if you’re used to DIYing your vehicle, you can learn more about error codes using this OBD-II database.
If you run into trouble, then you can always consult trusted service centers in your area to hire professional help. These experts will have the correct tools and the know-how to help you repair your vehicle.
