Description

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.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P2282 Intake Manifold Air Leak

Conditions for Running the DTC
    •  DTCs P0107, P0108, P0112, P0113, P0117, P0118, P0122, P0123, P0171, P0172, P0174, P0175, P0222, P0223, P0300-P0306, P0401, P0404, P1128, P2100, P2101, P2108, P2122, P2123, P2127, P2128, P2135, P2138, P2176, P2227, P2228, P2229, P2413, and U0107 are not set.
    • Battery voltage is at least 10.5 volts.
    • Intake air temperature (IAT) is at least 69°C (156°F).
    • Engine coolant temperature (ECT) is at least 0°C (32°F).
    • The engine has been running at least 15 seconds.
    • The engine is running in Closed Loop at idle.
    • The throttle position sensor angle is less than 1 degree.
    • The vehicle is in PARK with all engine accessories turned OFF.
    • DTC P2282 runs once per drive cycle when the above conditions are met.

Conditions for Setting the DTC

Either of the conditions below are present:

    • The estimated volume of air is 150 L/min (39.65 gal/min) or more when the manifold absolute pressure (MAP) is 47 kPa.
    • The estimated volume of air is 120 L/min (31.69 gal/min) or more when the MAP is 65 kPa.

Action Taken When the DTC Sets
    • The PCM illuminates the malfunction indicator lamp (MIL) after 2 consecutive ignition cycles in which the diagnostic runs with the fault active.
    • The PCM records the operating conditions at the time the diagnostic fails. This information is stored in the Freeze Frame buffer.

Conditions for Clearing the MIL/DTC
    • The MIL turns OFF after 3 consecutively passing trips without a fault present.
    • A history DTC clears after 40 consecutive warm-up cycles without a fault.
    • Perform the scan tool Clear DTC Information function.

Test Description

The numbers below refer to the step numbers in the diagnostic table.

  1. The Diagnostic System Check - Vehicle prompts the technician to complete some basic checks and store the Freeze Frame data on the scan tool, if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later reference.

    2.

  2. This step prompts the technician to check for any condition that can allow air to enter the engine. Any condition that can affect the idle speed of the engine must be repaired first, in order to enable proper diagnosis of the DTC P2282.

    3.

  3. A dirty throttle valve can affect the airflow through the throttle body and into the engine. Clean the throttle valve is necessary before performing the Idle Learn Procedure.

  1. Inspect the engine for any of the following conditions:
    2. • A stuck or damaged throttle valve or throttle body
    • A vacuum or intake air leak
    • An evaporative emission (EVAP) system malfunction
    • Faulty positive crankcase ventilation (PCV) system operation--Refer to Crankcase Ventilation System Inspection/Diagnosis .
