Lexus LC Manifold Pressure Sensor Issue

I'm having trouble with my 2021 Lexus LC, gasoline engine. The check engine light is on, and engine power is way down. It feels sluggish, and fuel consumption has increased. I suspect a faulty manifold pressure sensor and maybe a vacuum leak. Anyone else seen this with their LC?

I had similar symptoms on my LC a while back. Check the manifold pressure sensor; that could be it.

Thanks! Could you tell me what you checked on the manifold pressure sensor? Did you notice any other symptoms? Any details would be great!

I didn't check much myself, tbh. The symptoms were pretty much identical to yours, so I took it straight to the shop. They confirmed it was the manifold pressure sensor and sorted it out. Best to get it checked professionally, just in case.

Understood. Thanks; I appreciate the advice. I'll take it to my local workshop for diagnostics ASAP. It was the sensor, and the leak was large, as I suspected. New sensor and labor came to 235€. Thanks again!
