P2693 Meaning
Each injector has a code stored in the Electrically Erasable Programmable Read-Only Memory (EEPROM) that provides information to the Electronic Control Unit (ECU) about this injector’s deviations from a theoretical average injector. The Powertrain Control Module (PCM) sets the OBDII code if the injector code is missing or invalid.
