RC hybrid oil temperature sensor issue

I've got a 2015 Lexus RC hybrid with 165853 km. I'm seeing a persistent warning light and an error in the memory. Plus, the oil pressure light comes on and off. Diagnostics point to a faulty engine oil temperature sensor, maybe a bad cable or plug. Anyone else seen this on their RC?

Summary of the thread

A 2015 Lexus RC hybrid is experiencing a persistent warning light and intermittent oil pressure light, with diagnostics indicating a potential issue with the engine oil temperature sensor, possibly due to a faulty cable or plug. Another owner with a similar issue reported erratic oil temperature readings before resolving the problem by replacing the sensor. The suggested solution is to replace the sensor, which has been quoted at 95€.

Sounds familiar! I've had something similar happen with my RC. Is your oil gauge also acting up, giving you erratic readings?

Are you referring to fluctuations in the indicated oil temperature, or are there other anomalies you observed? Any details regarding the specific behavior of your oil gauge would be appreciated.

Yes, the temperature readings were all over the place before the warning lights came on. Eventually, I had to take it to a workshop. They replaced the sensor and the issue was resolved.

Thanks, that confirms it for me. I'll book it in for a sensor replacement. They quoted me 95€.
