Peugeot 1007 engine trouble

I'm having trouble with my 2008 Peugeot 1007, gasoline engine, 243992 km. The check engine light is on, engine power is reduced, response is poor, and fuel consumption is higher. Could this be a faulty manifold pressure sensor, maybe from a large vacuum leak?

A 2008 Peugeot 1007 with a gasoline engine is experiencing engine trouble, including a check engine light, reduced power, poor response, and increased fuel consumption. The issue is suspected to be related to a faulty manifold pressure sensor, potentially caused by a large vacuum leak. A diagnostic test confirmed a large vacuum leak, necessitating both the repair of the leak and the replacement of the manifold pressure sensor to resolve the problem.

That sounds familiar. I had a similar experience with my old Opel Astra. Check engine light, loss of power, the works. Could be a faulty MAP sensor, but did you check for vacuum leaks? They can cause all sorts of havoc. What diagnostic codes are you getting?

The diagnostic code indicates a problem with the manifold pressure sensor. Is it possible that replacing the sensor alone might not fix it if a vacuum leak is present?

You're right to be skeptical. Replacing the sensor might only be a temporary fix. If there's a vacuum leak, it'll keep messing with the readings and likely damage the new sensor eventually. Have you considered a smoke test to pinpoint the leak?

I had the car diagnosed, and a large vacuum leak was found. I needed both the leak repaired and a manifold pressure sensor replacement. Total repair cost: 235€.
