P062F - OBD Trouble Code

<<See All OBD Codes

Your vehicle has a Powertrain control module or PCM, that performs several important functions for the car. Of these functions is management of various systems properly, so that they all work in sync and provide the best ride for you. The fuel system, ignition system, traction control systems, anti-lock brake and transmission are just few of them, related to this OBD code error. In-order to manage them efficiently, the PCM runs a self-diagnosis function. This is basically done by performing mathematical calculations, as long as they are in congruence with the expectations of the PCM it’s fine, once the result of the calculations isn’t as expected by the PCM, it will set the error code P062F.

This code can be a little tricky even though it’s generic and applies to all OBD-II vehicles. So, if you own a Toyota, Ford, Nissan, Chevy etc. to name few you’re susceptible to this code. The steps for diagnostics and repair differ from model to model (depending on year, make, model, and PCM configurations). Basically, when you notice the P062F code is set, it’s because an internal performance error is noticed by the PCMs electronically erasable read only memory (EEPROM). Other controllers of your vehicle may have also detected this internal PCM error in the EEPROM and led to the storage of error P062F.

What causes this problem with the Internal Control Module EEPROM Error

• Defects in the controller or error in programming
• PCM is overheated
• Damage caused by water
• A blown fuse or poor controller power relay
• Visually Open or shorted circuit or connectors present in the CAN harness
• Insufficient ground for the control module
• Defective EEPROM

1. Power Relay - Repair it, if that doesn’t resolve the problem then replace easily from the comfort of your home at Parts Avatar.
2. PCM Fuse - A defective fuse can cause a lot of problems, assess for repairs otherwise opt for a new one.
3. Transmission Control System - Sometimes the whole module requires replacement, don’t worry and order the best quality TCM compatible with your vehicle with us.
4. Electronically Erasable Programmable Read Only Memory Or EEPROM - Try to repair it, if you need a replacement, simply check for one on our website, and avail free shipping on order over CAD $99.
5. Powertrain Control Module - This can be a big expense and require programming by a professional, buy the best online and have them delivered to you within few days.
6. Malfunction Indicator lamp - This could be repaired easily, try that first and if needed replace it.
7. Controller Area Network - Fix it via repairs, otherwise replace it.

Here’s your go-to list of common symptoms found in the OBD error P062F

Common Symptoms

• Wide Ranging drivability issues concerning the Engine/Transmission

Below are some steps to diagnose this error:

Programming equipment holds great significance in the diagnosis of this error. Only a trained and experienced professional technician can diagnose this error code. Using the equipment will enable the mechanic to reprogram, replace a defective controlled and successfully repair your vehicle.

All the ECM/PCM related codes will have to be dealt with first (if present), only then should one proceed with diagnosis. Preliminary tests will help rule-out any issues with the individual controller. For this, keep the following handy; diagnostic scanner, digital volt/ohmmeter (DVOM), reliable vehicle information source. Start off by connecting the scanner to the diagnostic port of the vehicle and retrieve all the stores codes, and remember to freeze frame data. Note down all the information, as this will come handy when diagnostics becomes complicated. Now, clear all the codes and take your vehicle for a test-ride, and wait until either the code is re-set or the PCM enters ‘readiness’ mode. If the latter happens, then it’s safe to conclude the code as intermittent and hence would be more complicated to diagnose. Be mentally ready that the condition that has caused the code to reset may have to worsen before accurate diagnostics can be made. If, the former has happened, perform the preliminary tests.

Take out the vehicle source information you gathered earlier and look for technical service bulletins (TSB) for the code and parallel vehicle information that matches the vehicle you’re trying to diagnose. See if you can find the accurate TSB, then read through and follow he diagnostic information. Using the same vehicle information source, find the connector face views, connector pinout charts, component locators, wiring diagrams, and diagnostic flowcharts coinciding with your vehicle. Using the DVOM test controller power supply fuses and relays, also test and replace all the blown fuses as per need. Ensure you test the fuses with the circuit loaded, if they appear to functioning as normal proceed to a visual inspection. Here, you are looking for any controller related wiring and harnesses anomalies. Remember to also check through the chassis and engine ground junctions.

Your vehicle information source will guide you on locating the ground locations for related circuits, use the DVOM again to test the ground integrity. Again, visually inspect system controllers, this time you’re looking for any damages caused by heat, water or collision. If you do find any controller that is damaged, by water especially, you have to consider it defective and accordingly replace it.

Common Mistakes When Diagnosing the P062F Code

• Failed Control module
• Malfunctioning of the Powertrain Control Module (PCM)
• Wiring showing a wide range of issues
