Question about Cars & Trucks
Looks like could be caused by one of several sensors.
I did find thisP04D9 EGR feedback saturation This OBD monitor indicates if the burned air fraction error is saturated against a high or low limit. The logic for the monitor evaluates the time spent at saturation and compares the ratio between the time spent in a saturation mode and the total time engine running. A fault is reported whenever the ratio exceeds the fault limit.
P04D9 EGR system: Feedback control(Saturated Low)
Enable conditions: Engine torque 300 - 2500NM,Exhaust Mass Flow 0.1 kg/s, Ambient Air Temperature-8 -55C, Barometric Pressure 75 - 105 kpa, Coolant Temperature>65 C
Disable Conditions No active DTCs P0069 P046c P0234, P0299, P0401, and P0402
Some possible causes
P0069 Intake manifold pressure sensor evaluation
P046c EGR differential pressure sensor: DP Sensor rationality
P0234 Comparison of actual boost pressure, Overboost, to modeled boost pressure
P0299 Boost Pressure: Underboost, Comparison of actual boost pressure to modeled boost pressure
P0401 EGR system (low flow)compare demanded egr flow to actual
P0402 EGR System (High Flow)compare demanded egr flow to actual

p1133, is a bad heater on the O2 sensor. Usually the sensor, some times the wire, rarely the PCM. bank 1 sensor 1.

its a 2016 should be under warranty bring to dealer if you start tinkering under hood it is possible to void a warranty
