Engine Failsafe Prog

[CGSTL]

2005 4.4i

I replaced my AFE CAI airbox with the stock airbox and within 1 minute it threw the error of ENGINE FAILURE PROG and I had to limp home. Now it seems to idle fine but it still has the error and a YELLOW BRAKE light is on in my dash and the YELLOW 4x4 warning light is on.

What could I have done by just putting the stock airbox back on? Could I have goofed with that wire/harness connected to the air hose leading to the engine?

Thanks for the help!!!

UPDATE: 4x4 light and BRAKE warning lights are no longer lit.
ENGINE FAILSAFE PROG still on.

Any ideas?

minute of driving the same thing. Its got my mechanic stumped. any help would be appreciated
