Ford Explorer Jerking Whistling Hissing

Hi, I have a 2020 Ford Explorer with a gasoline engine. The check engine light comes on, and it's jerking when accelerating. I also hear a whistling noise and a loud hissing when accelerating. Sometimes the engine stalls at idle, and I've noticed higher fuel consumption and reduced engine power. I suspect it might be a boost leak, could it be the boost pressure sensor?

Sounds familiar. I had a similar issue with my Explorer. Have you checked the cable and plug connection of the boost pressure sensor? Those can sometimes be defective.

Where exactly is that boost pressure sensor located? And how would I check the cable and plug? I'm not very experienced with car repairs.

It's usually located near the air intake or turbo system. If you are not experienced with car repairs I would recommend going to a workshop to avoid further damage. They can diagnose the problem correctly. It really does sound like a faulty connection though.

Thanks for the info. I took it to the workshop, and you were right. It was the cable connection of the boost pressure sensor. Cost me 95€. All good now!
