Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P062F: General Description
The powertrain control module (PCM) is equipped with an electrically erasable programmable read-only memory (EEPROM). The data (control learn data, etc.) for powertrain control and information (vehicle identification number (VIN), etc.) related to the vehicle control is stored in the EEPROM, so that it can be maintained even when power is not supplied to the PCM, such as when the 12 volt battery is disconnected. When powered up, the CPU retrieves the stored information from the EEPROM, as well as writes data to the EEPROM (control related data is written when the vehicle is turned to the ON mode, and vehicle information when commanded from the HDS). When the data retrieval or data writing process is not finished normally, the PCM detects a malfunction and stores a DTC.
