LFA Manifold Pressure Sensor Issue

Hello, I'm having a problem with my 2012 Lexus LFA with a gasoline engine. The check engine light is on, and I've noticed reduced engine power, poor engine response, and higher fuel consumption. I suspect it might be a faulty manifold pressure sensor. The car has 90192 km.

Hey! I had similar symptoms with my LFA. Check engine light, sluggishness, and guzzling gas like crazy. Did you check for any vacuum leaks? That's what caused my headaches!

Thanks for the tip! How did you determine that it was a vacuum leak, and was it definitely related to the pressure sensor?

Alright so, it was throwing codes related to the manifold pressure. My mechanic used a smoke tester, and it turns out there was a big leak around the intake manifold gasket. Replacing the gasket and the sensor fixed everything. Honestly, I'd just take it to a trusted mechanic at this point. Saves a lot of guesswork!

Thanks. I'll take it to a workshop and mention the possibility of a vacuum leak and the manifold pressure sensor. I appreciate the help, it looks like the problem was indeed a large vacuum leakage caused by a faulty manifold pressure sensor. The sensor replacement cost me 235€.
