Good point. How did you diagnose your Astra's issue? Did you have to replace the sensor, or was it wiring as well?

In my case, the garage confirmed it was a faulty sensor. I'd suggest taking your Lexus to a workshop. They can use professional tools for detailed testing and pinpoint it.

Thanks for the insight. I took your advice and went to a workshop. Turns out, it was exactly what I suspected. The cable for the component was defective. They fixed it for 95€, and now she's purring like a kitten again. Appreciate the help!

Interesting problem. I had something similar with my old Opel Astra, although the root was different. Engine light, rough running… Are you positive the sensor itself is functional, or might it just be reporting incorrect data?
