DTC P2282: Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The DTC P2282 Intake Manifold Air Leak diagnostic monitors the volume of air consumed at idle speed. The powertrain control module (PCM) controls the throttle actuator control (TAC) motor in order to regulate the air flow through the throttle body. The amount of air flowing through the throttle body will normally determine the engine speed. If there is an intake air leak or a malfunction in the positive crankcase ventilation (PCV) system excess air can enter the intake manifold affecting engine speed. The PCM uses sensor input in order to determine an estimated volume of air that is used during normal idle conditions. If there is any excess air, the estimated volume of air will be more than the expected value and DTC P2282 will set.
