Palio diesel manifold pressure sensor issue

My 2010 Fiat Palio diesel has a check engine light at 210196 km, reduced power, poor response, and increased fuel consumption. Diagnostics point to a faulty manifold pressure sensor, maybe a vacuum leak. Anyone seen this?

I had similar symptoms with my Palio, though I didn't do the diagnostics myself. The pressure sensor was the problem, I think. Any unusual idling or engine noises?

No idling issues or weird noises, just problems under load. What fixed it for you, specifically the sensor replacement?

No idling issues and problems under load makes the pressure sensor likely. Replacing it fixed my issue. Get a qualified technician to check and repair it. My sensor replacement, with labor and taxes, was 235€. Expect something similar.

Thanks, I took it to a workshop. They found a faulty manifold pressure sensor and replaced it. The problems are gone. Your advice really helped.
