P2DE0Cold Start Fuel Injection Quantity C Lower Than Expected

P2DE0 indicates that during a cold start, the engine control module (ECM) calculated an expected fuel injection quantity for cylinder bank C, but the actual measured quantity was lower than that target. The ECM monitors injection behavior and sets this code when the delivered fuel volume falls short of the commanded amount during the cold-start enrichment phase.
