P219D Honda Code - No. 2 Cylinder Air-Fuel Ratio Variation
Quick Answer
The Powertrain Control Module (PCM) detects the imbalance amount from the sizes of the 0.5-order and 1.0-order components compared to 0.8-order excitation input by the fuel injection to determine the air/fuel ratio variation between the cylinders. Common causes include Faulty fuel injector, Fuel rail clogged, Intake manifold air leak/clogged. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
