Default Check engine light?

My check engine light started to come on a few times lately during heavy acceleration. But today it came on and off cruising on the highway.
All systems seem normal, car idles fine...
What could have changed and cause this? I read that this is emissions related.
AFR meter looks like always.
I have about 9k miles since installing th eaton SC.

Hi Sab,
Could be nothing more than an intermittant lead/connector. Have a good look at Temp sensor 2 connector and wiring. If this goes open or short circuit the LH ECU will revert to a default "normal temprature" setting, and will output a fault code.

The check engine light is for emmission type faults.....
