Well, you have some problems here, did all of these codes come up at once? If so, I would think the ECU is bad or you have a bad ground.
1211: This code indicates a fault in the Throttle Potentiometer.
4112: This code points to a problem with the Air Mass Meter (MAF).
4122: This code usually signals a problem with the Lambda (Oxygen) sensor 2.
4121: This code refers to a fault with Lambda (Oxygen) sensor 1.
4114: This code indicates an issue with the coolant temperature sensor.
Let's check these sensors out to see if they are connected and if so, I would clear the codes and start the engine to see which ones come back first. Please let me know.
