Causes and Fixes P2279 Code: Intake Air System Leak
How to fix P2279 Code: Intake Air System Leak
A P2279 code is set when the computer (ECM/PCM) detects an intake air leak using information from a sensor.
Sensors reporting to the computer can vary but include the Mass Air Flow Sensor (MAF), Manifold Absolute Pressure Sensor (MAP), and Air Intake Temperature Sensor (IAT).
Causes include a bad hose, leaky gasket, or bad sensor.
Possible Causes of a P2279 Code:
Intake Air Leak (Vacuum Leak)
Bad Sensor (MAF, MAP, IAT)
Sensor Wiring

    I have a 2014 Honda Accord EX-L and all of a sudden the FCW system fail came on after I plugged a phone charger into the cigarette lighter/ charger port and the radio glitched out and turned off. I unplugged my phone charger turned the radio back on then plugged my charger back in and same thing happened again. Unplugged the car charger again, and left it unplugged then the FCW System Failed came on with the power steering, & LDW lights came on and they intermittently come and go. The car seems to be driving fine other than those lights and the FCW system failed. It’s currently at the dealership for the next few days after my regular mechanic said he couldn’t find anything wrong because when I took it to him it was one of the instances when the lights were off .

    2012 Jeep Grand Cherokee 3.6l V6. Had the same issue with the squealing without the belt even being on the engine My mechanic said it was definitely not the belt, the tensioner or the idle pulley. He couldn’t really even determine what it was causing the noise but he thinks it was something internal. If that’s the case, do you think it is those rocker arms you mentioned? He never mentioned anything about a PVC valve or starter. I’ve had the vehicle for two days now since his diagnosis and I have yet to hear any squealing? Any clue as to what’s going on?

Codes P0300, P0304 and P0306 also are showing but im sure if P0021 is fixed those will also. NO codes were being thrown prior to it being replaced just that metal ticking noise from bank 1 at low rpm. $5500 later im sick now, hoping the fix is easy and they don't have to get back in. question is do they have to drain the oil when replacing all that or just drain the radiator cause it has to be removed,

    • @HVAC_Mechanic
      @HVAC_Mechanic День тому

      The radiator fluid likely was drained and radiator removed but the oil would not need to be drained. It could be something simple like a wiring connector that wasn't attached well and came off, or possibly the timing belt slipped. It will need to be diagnosed.

    • @HVAC_Mechanic
      @HVAC_Mechanic День тому

      Pressure reading can't be done very well with a mini split. The only thing that can be done if it is low on refrigerant, is with the unit on, add in small amounts of refrigerant slowly until it starts to cool again. Add refrigerant in small amounts as to not overfill it which will cause it to not work also. This is not the official way which is to vacuum it down and add in refrigerant by weight.
