Multiple engine lights on, help please

VSC light flashing, Check engine light on, Trac control light on, code P011B. I have been researching the issue and I’m not seeing any people that have it, so any help would be greatly appreciated. I’ve just finished changing the timing belt, the intake manifold gaskets, replaced my harmonic balancer, and done some small general maintenance things. 2008 Tundra, 4.7L V8, base.

 

Check for damaged wires. Look closely around the MAF plug. Any trauma to that harness will cause the lights you listed.

Look close at any wires you disconnected to do your repairs.

 

I would double check your ect wiring and MAF wiring. No shorts or cuts in wiring? All air out of coolant no air pockets? IAT is in the MAF fyi.
The chart is just some known issues but could be other areas.

 

Not sure if you have tech stream...but the Toyota DTC for P011b after testing is either good ,replace MAF, replace ECT or replace ECM. https://www.tovenza.com/engine_cool..._air_temperature_correlation_p011b_-1002.html

 

Cleared the code and the issue hasn’t popped up again, so I guess it was a one time thing. Thanks all for the advice
