I drove down a dusty road for about an hour in gravel terrain mode. Next day the engine check light came on along with a little rough engine symptoms. The symptoms subsided mostly but check engine light still on. I took it to autozone to get it coded. 22 codes showed up

P0441- evaporative emissions incorrect purge flow
B1A00- control module
U0138- lost communication with terrain control
U015- lost communication with restraints control module
U0167- lost communication with vehicle immobilized control module
P0513-incorrect immobilizer key
P0101-mass or volume circuit range / performance
P0116-engine coolant temperature sensor 1 circuit for performance

there are are some other codes for restraints

please help? Any ideas with what might be wrong?

 

Make sure your gas cap is on tight.

Check to make sure the wiring to the coolant temp sensor didn't shake loose. If the connection is good clear codes and drive it see what pops back up. Most if those codes are just clutter in the system

 

...I'd be looking at the MAF Sensor.

 

I cleaned the sensor and throttle body and everything runs fine. I had a KN filter and I think the oil from it messed the sensor up.

 

...I've heard that can happen.
