P268ECylinder 3 Injector Data Incompatible
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- For cylinder 3 the controller compares the injector's correction value with what its software accepts. Ford's 2023 diesel OBD summary explains the idea well: each injector's code, kept in EEPROM, describes how far that unit departs from an idealised mean part, and a DTC is logged if the value is absent, out of range or its checksum is wrong. The monitor runs continuously and needs about half a second. GM's 2019 V8 diesel table 19OBDG04A rates P268E Type A, so the lamp lights in the first trip. Because only the data is checked, the injector itself may be perfect; the usual fix is to read the code off the injector head and program it into the controller.
- What you may notice
- Check engine light on

- RareStored injector data corrupted in the controller
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
