P1621 Fault Code: Understanding The Cause And Solution
The P1621 fault code refers to a problem with the Control Module Long Term Memory Performance. This code is related to the Powertrain Control Module (PCM) Electronically Erasable Programmable Read Only Memory (EEPROM).
The PCM stores important data in the EEPROM that is necessary for the engine and transmission to function properly.
Even if the vehicle’s battery is disconnected, this data remains intact. When the vehicle is powered up, the PCM checks the integrity of this data. If the PCM detects an issue with the long-term memory performance, it will trigger the P1621 fault code.
