P2BAB Toyota Code - NOx Emissions Exceeded Incorrect EGR Flow
Quick Answer
The Engine Control Module (ECM) operates the Exhaust Gas Recirculation (EGR) vacuum control valves and monitors the intake airflow to determine EGR flow. Common causes include Blocked Exhaust Gas Recirculation (EGR) passages in the manifold, Faulty Engine Control Module (ECM), Engine Control Module harness is open or shorted. 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.
