I pulled codes p0238, p2227 and p1101.. I changed the turbo sensor and the barometric pressure sensor or as they called it a MAP sensor..
Now I am pulling up p0236 ,p2227 and p0420.. what could it be?

Good afternoon,

236 is for a turbo boost leak somewhere in the turbo system. Make sure all the hoses are hooked up and tight.

2227 is for the intake air temperature sensor. Check the connector on the mass air flow sensor as the air temperature sensor is part of the MAP sensor. I attached the connector below.

420 is a catalytic converter efficiency code. The catalytic converter needs to be replaced.
