Code P2282 Buick Description

The DTC P2282 Intake Manifold Air Leak diagnostic evaluates the volume of air intake at idle speed. The Powertrain Control Module (PCM) operates the Throttle Actuator Control (TAC) motor to manage air flow through the throttle body. Typically, the airflow through the throttle body dictates engine speed. However, if there's an intake air leak or a fault in the Positive Crankcase Ventilation (PCV) system, excess air may infiltrate the intake manifold, influencing engine speed. The PCM utilizes sensor data to calculate the expected air volume during normal idle conditions. Should excess air be present, this volume will surpass the anticipated value, triggering Diagnostic Trouble Code (DTC) P2282.
