Bought the valve hoping to just switch it out, now you’re talking ohms and hoses and I’m wondering if my skills are adequate to even start haha. Thanks for the video!

[@adanz008]

Thanks a lot. Hard to find good mechanics in Houston even at dealer.

[@Motorcarnut]

Glad to help. It’s just like finding a good doctor, I hear you!

[@timtishchenko5673]

This video definitely helped me a lot, but I’m not quite sure how to take our the valve and check it out myself

[@Motorcarnut]

Thank you! It should be a couple of 10 mm bolts but make sure you have no cracks in the plastic hoses, they are known to crack.

[@steventrypuc7909]

Thank you

[@Motorcarnut]

You're welcome! Thanks for the feedback.

[@Timotije]

P2440 popped up today on my scannig tool, hopefully it's just crack on hose!

[@Motorcarnut]

Good luck!

[@mahamudfidow7352]

Thanks

[@Motorcarnut]

Sure, no problem. Thanks for the comment

[@mahamudfidow7352]

Thanks appreciated

[@jamarnembhard8308]

Great video! Question- do you know if the symptoms of secondary valve stuck open can cause the car to stall randomly? I have 2010 VW gti I have replaced my battery and alternator before I got the CEL code and my car would stall at random times. I thought the stall issue could be related to bad fuel filter until I recently got this CEL code. Thank you

[@Motorcarnut]

If that secondary air injection valve is stuck open it may cause the engine to stall because its letting in too much air and throwing the air fuel mixture off.

[@jamarnembhard8308]

@@Motorcarnut so I haven’t done any of the troubleshooting methods you stated in the video. I feel as though I just need to replace the secondary valve completely to resolve my issue

[@Motorcarnut]

Try that and see how it goes.

[@SmilingCrow-dc5ry]

What is the name of that hose that tends to crack??

[@Motorcarnut]

Fresh air pump hose
