Help with codes please
Fellas I just hit stateside for a little military leave. My car had been sitting at my for a while and was started once a week or so. I am now getting a flashing engine light, service traction system in the DIC and random rear tire sensor errors. I replaced the right rear sensor which was bad and now i'm getting a left rear flat in the DIC or no pressure readings on both rear tires. I disconnected the battery for about 30 min, the codes cleared for about an hour and returned.

Symptoms sound an awful lot like a failing battery.
Did you measure battery output?
Bet it's ~12VDC or less, should be around 14.
IF the car's been parked w/o a tender I'd bet a dollar to a dime your battery's failing. Merely starting isn't enough to charge a battery, IIRC car has to run at least 20 minutes for a successful battery charge.
Otherwise battery's being run down slowly 'til it's dead, usually first evidenced by weird electrical/electronic behavior as it's failing.
Have battery load tested & if it checks-out next step is checking alternator output.

With the engine running and the window down, close the car door. Raise the window and hold the up switch an extra 3 seconds. Release. Without lowering the window, hold the up switch again for 3 seconds. Release. Done. Don't forget the other window.
This will need to be done to both windows every time the car battery is disconnected, then reconnected.

Thanks!
I greatly appreciate the help gents! Turns out I had a bad ignition coil that was misfiring/working intermittently. Had coil replaced, that cleared the engine light and traction system light. I was throwing a P0300 code. Me not driving the car, I didn't have a good idea on the drivability. Runs like a champ....now for the rear TPS sensors...more to come. Batteyr is putting out right at 14V
