What is P2279 code?

OBD-II Code P2279 is defined as a Intake Air System Leak. The engine’s control module ((PCM) uses multiple sensors to determine how much air is flowing through the engine at any given time.

How do you fix a leaking intake air system?

How To Correct Intake Air System Leak Issue

  1. Make sure to relearn the throttle position for the ECM.
  2. Rehabilitate the leaking intake gaskets or seals.
  3. Carefully adjust the faults in the PCM.
  4. The ECU should be restored to working order.
  5. Recondition the non-functioning PCV valve or hose.

What causes intake air system leak?

A disconnected or broken vacuum hose. A faulty fuel injector seal. Leaky brake booster vacuum hose. Intake air temperature sensor leak.

What is an intake air leak?

When a vacuum leak occurs, some air enters the intake manifold without passing through the throttle body. The ECU, meanwhile, injects the amount of fuel necessary based only on the measured air-flow. This results in a lean fuel-air mixture, which then leads to erratic idling and lacklustre low-speed performance.

How much does it cost to fix an intake manifold?

The average cost for intake manifold gasket replacement is between $555 and $614. Labor costs are estimated between $217 and $273 while parts are priced between $338 and $340. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

What happens if your intake manifold is leaking?

A leaky intake manifold sucks outside air in, rather than dispersing air out. This can cause performance issues including poor fuel economy, decreased acceleration, and engine misfires. Coolant leaks can cause the engine to overheat, although they may not always be visible.
