P219A Jeep Code - Air Fuel Ratio Imbalance Bank 1
Quick Answer
The Cylinder Imbalance Detection requires that the Upstream O2 Sensors are capable of operating at high frequencies since an aged O2 Sensors response capability at a higher frequency range can be degraded. Common causes include Intake Manifold leak at a specific cylinder, Fuel Injector problem, Variable cam lift failure. 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.

Code P219A Jeep Description
Once active, the Cylinder Imbalance Detection monitor matches up the Upstream O2 Sensor signal with the corresponding cylinders on that bank. Each cylinder is monitored, and adjustments are made as needed for each cylinder to correct an air/fuel ratio imbalance. If an individual cylinder reaches a calibrated adaptation threshold (15%), the diagnostic monitor will be considered failing.
The Diagnostic Trouble Code (DTC) will be set when the Powertrain Control Module (PCM) detects that one of the cylinders on bank 1 has an air/fuel ratio imbalance of 15% when compared to the other cylinders on the same cylinder bank.
