Sluggish Suzuki Carry Points to Faulty MAP Sensor

As a Suzuki Swift (2001) owner, I experienced nearly identical symptoms last year. The engine performance issues and high fuel consumption turned out to be related to a faulty MAP sensor combined with a significant vacuum leak at the intake manifold gasket. What started as a simple automotive sensor diagnostic revealed a more serious underlying issue. The MAP sensor replacement alone did not solve the problem completely. The vacuum leak was causing incorrect readings, making the engine run rich and leading to poor performance. The repair required: MAP sensor replacement, Complete intake manifold gasket replacement, Vacuum line inspection and replacement, ECU recalibration after fixes Total shop time was about 4 hours. The vacuum leak could have caused long-term engine damage if left unaddressed, as the engine was constantly running with incorrect air-fuel mixtures. For your Carry, request a smoke test before any sensor replacement to check for vacuum leaks. Many times poor MAP sensor readings are symptoms of other issues, not the root cause. A proper diagnostic will save time and prevent unnecessary parts replacement.

Thanks for sharing your experience. I had nearly the same issues with my Carry back in 2020. I got the manifold pressure sensor replaced which helped with engine performance, and my mechanic also found some worn vacuum lines that needed attention. I would be curious to know how much you ended up paying for the complete fix. Also, have you noticed any recurring issues since the repair was done? The automotive sensor setup on these models can be a bit finicky, so I always like to hear about long-term outcomes after pressure sensor repairs.

After getting the repairs done, I can confirm the issues were completely resolved. The manifold pressure sensor was indeed faulty and needed replacement, plus the mechanic found a large vacuum leakage that was contributing to the problems. The total cost came to 235€ for both fixes combined. Since the automotive sensor repair and vacuum leak fix, the engine performance has been perfect with no recurring issues. The fuel consumption returned to normal levels and the sluggish acceleration completely disappeared. Looking back, getting a proper diagnostic was key, the pressure sensor replacement alone wouldnt have solved the underlying vacuum problem. The MAP sensor repair made a huge difference in how the engine runs. After 18 months, everything is still working as it should with no check engine lights or performance issues. The sensor replacement turned out to be a straightforward fix once the mechanic identified the exact problems.

My trip to the mechanic ended up being quite eye-opening. After reading about similar manifold pressure sensor issues, I took my Carry in for diagnosis. The mechanic found both a failing MAP sensor and significant vacuum leaks in the intake manifold system, exactly what others had mentioned. The total repair came to 280€, covering: New manifold pressure sensor, Vacuum line replacements, Labor costs, Diagnostic testing The car runs perfectly now. Fuel consumption is back to normal and the sluggish acceleration is gone. The intake manifold pressure readings are stable, and the check engine light hasnt returned. My new mechanic was thorough and transparent about the whole process, showing me the old damaged parts and explaining everything. Lesson learned, a proper diagnostic prevents overpaying for partial fixes. The car sensors all work together, so its worth having a skilled mechanic check the entire system rather than just replacing parts. Really glad I asked here first and went prepared with the right information.
