Q: What does code P2DDE mean?

Fuel Injection Quantity D Lower Than Expected. P2DDE indicates that the engine control module has detected the actual fuel injection quantity for cylinder bank D is lower than the commanded or expected amount, meaning the engine is receiving less fuel than the computer intended. The module compares commanded injection volume against feedback from the fuel system and sets this code when the shortfall exceeds calibrated limits.
