Steering Angle Sensor codes

Got 5 new DTC codes from my Jeep this last weekend.

(Didn't see these in the FAQ lists, maybe a mod can add them in.)

these are the values as superchips listed them:

C1239 - Steering Angle Sensor Erratic Performance
C123A - Steering Angle Sensor Not Initialized
C123F - Steering Angle Sensor Comparative Performance
C1240 - Steering Angle Sensor Overtravel Performance
C2205 - Steering Angle Sensor Internal

The effect is the TCS and ESP/BAS dash lights are on full time. Driving appears unaffected so far.

Taking it down to the dealership to see if my warranty is going to still apply, don't have much left from factory steering except the steering box and pitman arm, heh.

Immediately prior to the lights and beep, I had made a u-turn. Although nothing special about the turn, except my jeep beeped and I had the lights. /shrug

Its likely the angle sensor itself failed. Or the aftermarket steering somehow allowed the angle sensor to overrotate, but i'd doubt that

it was a bad steering sensor.

dealership is only about 5 miles from me, but by the time i got there the computer was having a field day over working itself trying to keep me 'stable' with the bad sensor.

dealership took care of it all and warrantied out the part.

only real question they asked was about all the dust inside the steering column.
