DTC codes / P2Dxx · Hybrid propulsion / P2DE3
P2DE3 means the engine control module (ECM) has detected that the cold-start fuel injection quantity for cylinder D is higher than the calibrated expected value. During a cold start, the ECM commands a specific amount of extra fuel per cylinder, and it monitors how much correction is needed; this code sets when the correction for cylinder D exceeds the allowed threshold.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
