Diagnostic Instructions
    • Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
    • Review Strategy Based Diagnosis for an overview of the diagnostic approach.
    •  Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptor

DTC P2282: Intake Manifold Air Leak

Circuit/System Description

The engine control module (ECM) compares actual vacuum reading of the manifold absolute pressure (MAP) sensor at idle to a calculated vacuum reading.

Conditions for Running the DTC
    • The evaporative emission (EVAP) purge canister commanded state is less than 100 percent.
    • The barometric pressure (BARO) is greater than 72 kPa.
    • The engine coolant temperature is greater than -10°C (14°F).
    • The intake air temperature (IAT) sensor is greater than -20°C (-4°F).
    • The ignition 1 voltage is between 11-16 volts.
    • The engine has been operating for 2 seconds.
    • The DTC runs continuously when the above conditions are met for 3 seconds.

Conditions for Setting the DTC

The ECM detects that the actual vacuum reading is greater than the calculated vacuum.

Action Taken When the DTC Sets

DTC P2282 is a Type B DTC.

Conditions for Clearing the DTC

DTC P2282 is a Type B DTC.

Circuit/System Verification
  1. engine running, observe the DTC information with a scan tool. DTC P2282 should not set.
  2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing
  1. Verify none of the following conditions exist:
    2. • The air intake duct system for loose connecting clamps, cracks, or other damage
    • A damaged throttle body blade or shaft
    • Splits, kinks, or improper connections at the vacuum hoses
    • An exhaust gas recirculation (EGR) system leak
    • Faulty positive crankcase ventilation (PCV) system operation
    • Carbon deposits on the throttle blade--Refer to Throttle Body Inspection and Cleaning.
    • Vacuum leaks at the intake manifold, throttle body, and injector O-rings
  2. If all conditions test normal, test the engine for proper camshaft timing. Refer to Timing Belt Replacement.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

    •  Throttle Body Assembly Replacement
    •  Air Cleaner Inlet Duct Replacement
