P2097 Acura Code - Post Catalyst Fuel Trim System Too Rich Bank 1
Quick Answer
The Engine Control Module (ECM)/Powertrain Control Module (PCM) detects oxygen content in the exhaust gas by the Air/Fuel Ratio (A/F) Sensor (Sensor 1), and it uses feedback control before the warm up three way catalytic converter (WU-TWC) to bring the air/fuel ratio in the air/fuel mixture close to the target air/fuel ratio. Common causes include Faulty Air/Fuel Ratio (A/F) Sensor (Sensor 1), A/F sensor (sensor 1) circuit range/performance, Fuel system too lean. 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.
