Tiburon Manifold Pressure Sensor Fault

Check engine light on my 2001 Hyundai Tiburon with a gasoline engine. Reduced engine power, poor engine response, and higher fuel consumption. Car has around 160099 km. Scan indicates a faulty manifold pressure sensor. I suspect a large vacuum leakage. Anyone else encountered something similar?

A 2001 Hyundai Tiburon experienced reduced engine power, poor response, and increased fuel consumption, with a check engine light indicating a manifold pressure sensor fault. The suspected cause was a large vacuum leak. A similar case suggested that replacing the MAP sensor alone might not resolve the issue, and a professional diagnosis, including a smoke test, was recommended. Ultimately, both the faulty sensor and vacuum leak were addressed, resolving the problem.

I had a similar problem with my Hyundai Tiburon (although it's a later model). The symptoms you described – check engine light, power loss, and increased fuel consumption – sound very familiar. Did the error code specifically point to the MAP sensor?

Yes, the error code directly indicated a fault with the MAP sensor. Did replacing the sensor solve the problem for you, or did you have to look into other potential causes?

In my case, replacing the MAP sensor didn't completely resolve the issue. It turned out there was a vacuum leak as well. I would suggest taking it to a trusted workshop so they can conduct a smoke test on the intake manifold. It's best to get it professionally diagnosed.

Thanks for sharing your experience! I appreciate the advice. I've taken it to a trusted workshop, they found a vacuum leak, and the MAP sensor was indeed faulty. After replacing the sensor and fixing the leak, the issue is resolved! The final repair cost was 235€.
