What does code P2DD7 mean?

Q: What does code P2DD7 mean?

Cold Start Fuel Injection Quantity B Lower Than Expected. P2DD7 indicates that during a cold start, the engine control module detected that the fuel injection quantity for bank B was lower than the expected value for the current operating conditions. The computer compares commanded fuel volume against what the oxygen sensor feedback and other inputs suggest actually occurred, and it sets this code when the measured or inferred delivery falls short of the target.
