2016 12" Macbook that is hardly used. Probably once per week since 2016.

After screen replaced for coating off 4 months ago then whole keyboard replaced because trackpad not clicking, genius informed me that one of the sensor failed during their test.

I followed up on what sensor that is. He said it for memory. Saying that any high usage will make the computer lag or freeze due to the senor failing. If the CPU is stressing then the computer may freeze.

Any insight on this? Sounds like a temperature sensor issue to me.

If it's under warranty. Have them replace it. If it is no longer under warranty. I'd try it out. If it experiences issues. Then sell it for parts. As replacing the sensor (ie motherboard) would cost way too much money.

The only sensor I could think of too would be a temperature sensor. One which is integrated. Which would likely result in the fans running at full speed and perhaps throttling. If it has actually failed.

By the way a client had a new iMac which had a faulty temperature sensor in a diagnostic. Applecare refused replacement of the motherboard as it had not actually failed. It's been two years now with no problems. The takeaway being only replace if Apple will pay for it. Otherwise see for yourself if it works fine. As their diagnostics aren't perfect.

It's out of warranty or else I would already have replace it. This is a 12" MB therefore has no fan.
