You have a bad sensor at one of the tires that need replacing that operates ABS and traction control. If you take it in to a shop it will run $130 but they can find which sensor is causing the problem. But if you do it you might have to replace all 4 sensors to make sure you got the right one. Every hard to diagnoses. Its better for the shop cause they can get electrical read outs for each sensor.

Sounds like your security system is shutting the car down. You should be able to leave the key on for 15 minutes and it will reset itself. Make sure you are using factory keys, and they are in good condition.

P1122 is a throttle position sensor code. P1629 is a theft deterrent system code. P1122 will set when the voltage signal from the throttle position sensor drops below 0.1 volts. Normally, the sensor should measure between 1 volt at idle and 4 volts at full throttle. A failed throttle position sensor could easily cause your problem.
As for the theft deterrent system code, with that code set, the car shouldn't start at all (if the code is active). With P1629, the engine computer should refuse to deliver fuel to the engine. This code can be stored for up to 40 warm up cycles before clearing itself, so unless it is currently active, there may not be any need to worry about it.
I would inspect the wiring and connectors leading to the throttle position sensor. If that wiring is good, I would replace the sensor and see where that got me. Give that a try and let us know how things go.

Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.
Thanks for using FixYa!
