S10 Jerking Acceleration Whistling Noise
Summary of the thread
The 2015 Chevrolet S10 diesel was experiencing jerking during acceleration, a whistling noise, increased fuel consumption, and occasional stalling, with the check engine light on. The suspected cause was a faulty boost pressure sensor or its connections. After cleaning the sensor connections with contact cleaner didn't resolve the issue, a mechanic confirmed the sensor was faulty and replaced it, resolving the problem.

Thanks for the reply! When you say "properly" check the sensor connections, what exactly do you mean? I visually inspected them, but I haven't done anything beyond that. Was there a specific area that was causing the problem on your Corsa, or was it just generally corroded?

Alright, what I mean is, sometimes a visual check isn't enough. The connector might look okay from the outside, but inside, the pins can be corroded or loose. Try unplugging the sensor, giving the pins a good clean with electrical contact cleaner, and making sure the connector clicks firmly back into place. If that doesn't solve it, you're probably looking at a faulty sensor or something more serious. Honestly, at that point, I'd suggest taking it to a workshop. Could save you a lot of hassle.

Thanks for the detailed advice! I followed your suggestion and cleaned the sensor connections with contact cleaner, but unfortunately, that didn't fix the problem. I took it to a local mechanic, and it turns out the boost pressure sensor was indeed faulty. They replaced it for 95€, and now everything is running smoothly again. Appreciate your help!

Hey! That sounds eerily familiar. I had almost the exact same symptoms in my old Opel Corsa a few years back. Check engine light, weird noises when accelerating, and the whole shebang. Turned out to be a boost leak, and yeah, the pressure sensor was involved. Did you properly check the sensor connections? Maybe use some contact cleaner spray?
