Fuel Injector Offset Maximum Learning Limit Reached - Cylinder Number 6
P02D7 — Fuel Injector Offset Maximum Learning Limit Reached - Cylinder Number 6
System: Powertrain | Type: Generic (OBD-II Standard) | Make: Generic
P02D7 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.
Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.
Because P02D7 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.
The Engine Control Module (ECM) sets this code when the fuel injector offset learning for cylinder 6 reaches its maximum allowable limit. The injector offset is an adaptive value used to correct injector flow variations and ensure precise fuel delivery. If the ECM has to compensate beyond its programmed range, it indicates an issue with the injector or fuel system, potentially leading to poor fuel economy, rough idling, misfires, or drivability issues.
