Ford Ikon Jerking Whistling Hissing

My 2007 Ford Ikon (gasoline) with 240478 km is acting up. The check engine light is on, and it's jerking when I accelerate. There's also a whistling noise that turns into a loud hissing under acceleration. Sometimes it even stalls at idle. Fuel consumption is up, and power is definitely down. Suspect the boost pressure sensor, maybe a bad cable or plug connection?

A 2007 Ford Ikon is experiencing issues such as jerking during acceleration, a whistling noise turning into a loud hissing, stalling at idle, increased fuel consumption, and reduced power, with the check engine light on. The suspected cause is a faulty boost pressure sensor or its connections. After inspecting the intake manifold area and checking for loose or damaged hoses and cables, the problem was identified as a damaged boost pressure sensor cable, which was replaced, resolving the issues.

Did this summary help you solve your problem?

Sounds rough. I had similar symptoms in my old 2012 Opel Astra, though no whistling, just hissing. Check engine light, jerking, and power loss, all pointing towards boost issues. Have you inspected the intake manifold area for any obvious cracks or loose hoses?

Intake manifold? I was focusing on the boost sensor itself and its connections. Where exactly should I be looking on the manifold? And what am I looking for specifically?

Yeah, sorry, I should have been clearer. The boost sensor is usually somewhere around the intake manifold. Check all the hoses connected to it and the manifold itself for cracks or if they're loose. If the sensor's cable or plug looks damaged that is most likely your problem and needs fixing. If it isn't the sensor itself, get it checked at the workshop, it is most likely the turbo.

Thanks for the insight. Turns out it was the boost pressure sensor cable. Replaced it for 95€ and it runs fine now.
