Diagnostic Aids: Verify the integrity of the PCV system. Refer to Section 1, Positive Crankcase Ventilation (PCV) System for
system information.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HG.
P2281 - Air Leak Between MAF And Throttle Body
Description: This DTC sets when the PCM detects an air leak that exceeds a calibrated limit for greater than 5 seconds. If
the airflow entering the engine exceeds the airflow through the throttle, a leak is detected and this diagnostic fails.
Possible Causes: • Unmetered air leaks between throttle body and intake valves
• Air leaks at the intake manifold
• Positive crankcase ventilation (PCV) system is leaking
Diagnostic Aids: Verify the integrity of the PCV system. Refer to Section 1, Positive Crankcase Ventilation (PCV) System for
system information.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HG.
P2282 - Air Leak Between Throttle Body And Intake Valve
