Lexus LC Overheating Radiator Fan Speed Sensor

Hi, I have a 2021 Lexus LC hybrid. Recently, the engine overheated, and the check engine light came on. I've checked the coolant level, and it seems fine. Could it be a radiator fan issue?

I had similar overheating problems on my LC. Loud fan noise too? If so, it's likely the radiator fan speed sensor. I wouldn't drive it much until you get it checked.

Loud fan noise yes, now that you mention it. Is the speed sensor integrated into the fan motor or is it separate?

Yep, sounds like the same issue. I'm pretty sure it's part of the fan assembly, but don't quote me on that. I took mine to a shop, they sorted it pretty quickly.

Thanks for the heads up. Turns out the speed sensor was defective, like you said. Got the radiator fan replaced for 250€. Appreciate the help!
