Check Engine Light

P2282 code definition

Air Leak Between Throttle Body and Intake Valves

What the P2282 code means

P2282 is an OBD-II generic code for the engine control module (ECM) monitoring the vacuum in the intake manifold at idle. This code is triggered if excessive air is getting into the intake unmetered which indicates a vacuum leak.

What causes the P2282 code?

  • The engine control module (ECM) monitors the manifold absolute pressure sensor for excessive air entering the intake manifold from a vacuum leak.

  • The intake has a vacuum leaking at a gasket or a defective cracked manifold.

  • The PCV system is stuck open causing excessive air to enter the intake.

  • The throttle body shaft or gasket behind it leaks air into the intake.

  • The vapor purge control valve may not be sealing flow of vapors at idle.

What are the symptoms of the P2282 code?

  • The Check Engine Light will be illuminated and the code is set in ECM/PCM memory as a fault.

  • The vehicle may run rough and misfire or stall if the computer cannot compensate for the vacuum leak.

How does a mechanic diagnose the P2282 code?

  • Scans for codes and documents the code in the ECM/PCM memory, and looks at the freeze frame data for the problem before clearing the codes and retesting

  • Checks the PCV system and the vapor control valve for sealing properly

  • Checks the throttle body and intake for any vacuum leaks

Common mistakes when diagnosing the P2282 code?

  • Clearing ECM memory codes before checking the freeze frame data
  • Failing to clear the ECM codes after the repairs are done
  • Failing to verify the vapor purge valve is sealing properly

How serious is the P2282 code?

Code P2282 is an indication that the ECM/PCM detects a vacuum leak and unmetered air is getting into the engine causing a lean idle condition. This could cause stalling and emission test failures.

What repairs can fix the P2282 code?

  • Replacing the PCV valve
  • Replacing the vapor purge control valve
  • Repairing vacuum leaks in the intake manifold or throttle body
  • Replacing or repairing vacuum lines that are cracked or broken and leaking

Additional comments for consideration regarding the P2282 code

Code P2282 is a code that indicates there is unmetered air getting into the intake system. If no vacuum leaks are found externally, then you may have an engine intake valve that is not sealing in one of the cylinders, and a compression test and engine diagnosis may be needed. This is not very common but one should be aware of this possibility.
