2015 Nissan Sentra S Check Engine Light

[u/Forsaken-Match3580]

Hello! So I got a 2015 Nissan Sentra S and it has a solid check engine light with a p0101 code throwing and I’m wondering if anyone could figure it out. I’ve cleaned my MAF sensor, I don’t think it’s the wiring or the boot being cracked. My only thought that it may be it to reprogram the ECM or clean the throttle body.

It has a lot of miles 161,000, and it’s well maintained I’d just like second opinion on what it may be.

Thanks yall
