    Check engine light came on. code reader said Sec Air Inj Sys Switching Valve stuck Closed Bank1
    was wondering how serious this problem was

      P2441 = Secondary Air Injection System Switching Valve Stuck Closed Bank 1

      Possible causes:
      - Faulty Vacuum Switching Valve (VSV)
      - Vacuum Switching Valve (VSV) harness is open or shorted
      - Vacuum Switching Valve (VSV) circuit poor electrical connection
      - Faulty Pressure Sensor
      - Faulty Air Switching Valve

      What does this mean?
      When is the code detected?
      If the Engine Control Module (ECM) receives the pulsation signal from the sensor despite the ECM ordering the VSV to close the air switching valve, or if the ECM has not received the signal from the sensor despite the ECM ordering the VSV to open the valve, the ECM interprets this as a fault in the secondary air injection system and the code is set.

      Possible symptoms
      - Engine Light ON (or Service Engine Soon Warning Light)
      P2441 description
      To accelerate the activation of catalyst when warming up the engine, the air injection system pumps the secondary air to the exhaust manifold by pressure. The secondary air is supplied by the air pump and it is pumped to the exhaust manifold through the air switching valve. Open and close movement of the air switching valve is regulated by the Vacuum Switching Valve (VSV).The air pump and the air switching valve are observed by the Engine Control Module (ECM) and are used to detect malfunction in this system. The ECM monitors the secondary air injection system and detects malfunction using a pressure sensor located on the air switching valve.

      The ECM observes the pressure in the secondary air passage using the pressure sensor located on the air switching valve in the secondary air injection system. The sensor detects an exhaust pressure in the secondary air passage.

    What is wrong when cruise light &check engine light comes on at same time?

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.
      Have the check engine light tested / scanned for free - most local auto parts stores do this service for free.

    My 2002 Subaru outback started shaking and making loud noises felt like it was going to stall at a stop light.
    I just had a thermostat replaced a week ago, the shop told me it would need the timing chain replaced and the water pump, eventually. so would this be the problem??

    My check engine light came on. Code was for camshaft position sensor. What could be wrong. Car has only 5k miles on it.
    Dealer said it was because oil was a litle overfilled. The oil was changed in November, doubt that's the reason. Drained oil anyway, refilled exactly to fill line on stick and within 25 miles of driving light came on again.

      Since the vehicle is still covered by the warranty - recommend to return to the dealership for the warranty repairs

      I think the dealership is trying to snow you! Overfilling the oil will not cause
      this sensor to go bad. Besides, like Jimm said the car is under warranty.
      Five years or 50,000 miles.

    After putting gas in my car, it sputtered and died. Now it won't start.
    Mechanic checked fuel pump, and its working. Checked coil pack and crank sensor. They are working. Need some ideas of what else might be wrong.

      Some ideas:

      - Wrong type of gas. My 1994 Subaru Legacy definitely has a preference for straight gas, no additives at the pump.
      - Too much moisture/water in the gas (try an additive like Heat?)

    After putting gas in my car, it sputtered and died. Now it will not crank at all.
    The problem is definitely not the crank position sensor or coil pack, because those have been replaced and it did not help. Fuel pump is working fine, also.

    No check engine light and the motor began to knock!? Rebuild, adjust the valves, new motor?

      The turbo failed-- & you kept driving-- until the turbo sucked
      out all the oil & ruined the motor

      So, less than two miles ruined my motor, and yet others drive with a knock for hundreds of miles?
    • Teddy B
      12/12/2014 Teddy B
      Big difference from an engine knock due to a cylinder misfire or other reasons
      & you driving with no oil in the motor

      You drove two days after the oil light came on & the turbo was red hot

      Why is your mechanics advice not sufficient ?

    Timing advice. Lining up the cams and crank without the aid of the old belt
    I was preparing to change the timing belt so I pulled the timing belt cover off. Was lining up notches by turning crank with the belt on. As I was turning, everything slipped. I thought I had stripped the crank bolt, broke my ratchet or my socket. Upon inspection, ...

      Now you first wash down the front of the motor with mineral spirits or brakleen

      Then you get a kit that includes an instruction booklet,water pump,timing belt &
      all required new pulleys

      With the instructions & some You Tube Video you will be fine & learn alot

      In the future-- watch the videos & paint the gears & belt-- before removing the belt

      In your case it was stripped & gears most likely in the wrong place

      Just to be safe- do a cylinder leak down test- to be sure the valves
      were not hit & damaged & all cylinders seal properly

    Why won't my check engine light come on when it is obvious that I have some serious engine problems?
    This is an edit to prev. info. Check engine light only on briefly w/o enough time to use OBD. How do I diagnose problems w/o any idea where to start in my particular problem? Lots of posibilities but can't just start buying parts one at a time and hope I hit on ...

      You do not need a check light on to have problems

      You will have data with or without dtc (codes stored) if you
      were to use a professional scan tool to look at it

      If you have a code reader they all have different capabilities

      What you want is to road test & see if the Emission Monitors all run
      There should be about 13 & most cars & inspection stations only
      look at 8 If they fail then you have work to do

      No you do not buy any parts until you learn how to perform component testing
      & find a failed part No problem found,no need for parts Your correct there

      The coolant should be 50/50 or 60/40 proper coolant & distilled water
      Is the coolant in the system & plastic tank staying in there,if not then maybe a
      head gasket as you said

      In all you have said what exactly is the problem?

      Have you done a cylinder leak down test-for valve issues
      A coolant combustion gas test -for head gasket
      Checked for a worn & jumped timing belt
      How about a worn out & partially blocked converter
      How is the fuel pressure & volume,does it hold

      If your issue or problem is not monitored then no check light
      If you have a head gasket failure but it doesn't over heat (Yet) then no MIL Lamp

    Think I have a blown head gasket
    Get a strong smell of antifreeze inside car when heater turned on. Also, cooling fans will not come on unless the A/C is turned on and then I get heat in car. Occasional 'pop' like small misfire or backfire. Feels like it is going to stall while driving - ...

    While driving vehicle feels like it is losing power and going to stall.
    Problem presents itself after a few miles of driving. Repeatedly pressing gas pedal seems to make engine run normally but for only a couple of minutes then repeats the problem. Occasional 'pop', like small backfire. Starts well and runs great between the power ...
