Partner engine losing power

My 2014 Peugeot Partner with a gasoline engine is giving me some grief. The check engine light keeps popping on, and the engine feels like it's lost power. It's sluggish, and I'm pretty sure I'm burning more fuel than usual. Any ideas? Mileage is only at 25192 km. Thinking maybe it's the manifold pressure sensor?

I had similar issues with my Partner, though I didn't check the mileage. Reduced power and the engine light were the first things I noticed. Did you happen to check for any vacuum leaks? A large one can definitely mess with the manifold pressure sensor readings.

Vacuum leaks, huh? That's interesting. Where should I be looking, specifically? Any common spots on the Partner that are known to cause trouble?

Without proper tools, it's tricky to pinpoint the exact location. My mechanic found it after a smoke test. With those symptoms pointing to the manifold sensor and large vacuum leak, I suggest taking it to a workshop to get it properly diagnosed. It could save you time and money in the long run.

Thanks for the advice! Turns out it WAS the manifold pressure sensor, likely caused by a vacuum leak as you suspected. The workshop confirmed it. Got the sensor replaced and the leak fixed for 235€. Running much better now!
