RX Hybrid rough running

I'm having trouble with my 2016 Lexus RX hybrid (184363 km). The check engine light is on and off, the engine runs rough, and it has stalled at idle. It also jerks during acceleration. I think it might be the fuel pressure sensor or a faulty cable/plug. Has anyone else had this?

A 2016 Lexus RX hybrid is experiencing rough running, stalling at idle, and jerking during acceleration, with the check engine light intermittently on. The issue is suspected to be related to the fuel pressure sensor or possibly faulty cables/plugs. A diagnostic scan confirmed a fault with the fuel pressure sensor, and the recommended solution is to have it checked and repaired at a workshop, which resolved the problem.

Hey! I have an RX too, and that sounds familiar. Check engine light, rough idle... I'd bet it's something to do with the fuel system. Is it throwing any specific codes?

Thanks! A scan said there's a fault with the fuel pressure sensor. Does that sound right, or should I check the fuel pump or fuel injectors too?

Fuel pressure sensor definitely sounds like the problem! I messed with mine, checking connections, but I'd just take it to a workshop. Save yourself the headache.

Thanks for the advice! I took it to a workshop, and it was the fuel pressure sensor. The repair was about 95€.
