Pathfinder check engine light and whistling

My 2014 Nissan Pathfinder hybrid is showing a check engine light. I've noticed reduced power, especially when accelerating. It also whistles sometimes. Mileage is at 33878 km. Any ideas?

Whoa, sounds familiar! I have a Pathfinder too. I had similar symptoms: check engine light, terrible engine response, and a LOUD hissing when I put my foot down!

Yeah, now that you mention it, I've had a couple of stalls at idle and the fuel consumption seems higher. What was it in your case?

Okay, sounds like the exact same issue I had. Turned out to be a defective electrical bypass valve, the boost pressure actuator was faulty. Apparently, it's a pretty common problem. I'd say take it to a workshop. I ended up paying around 250€ for the repair, so brace yourself!

Thanks for the info! Sounds like that's probably it. I'll take it in. Repair cost was similar, about 250€. Issue was a defective electrical bypass valve, boost pressure actuator.
