DTC P2282

DTC DESCRIPTOR

DTC P2282
Intake Manifold Air Leak

DIAGNOSTIC FAULT INFORMATION
Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Testing and Inspection

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 more 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 more 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. Operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. DTC P2282 should not set.
2. If the vehicle passes the Circuit/System Verification Test, then operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records List.

CIRCUIT/SYSTEM TESTING
1. Verify that none of the following conditions exist:
- 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.
- 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.

REPAIR INSTRUCTIONS
Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Verification Tests
