2005 Durango, 4.7, Limited, 4x4.

Having crazy codes lately.

P0070 and U1120.

The ABS sensor and the Transaxle Control Module.

These codes came after I went out to start my Dodge and it didnt even turn, Dead. Jumped it and thought i may have left a light on, but the next day, went out to start it and dead. SO im thinking something is drawing power.

Does the ABS sensor or Transaxle Control Module draw that much power to drain?

And where is the Transaxle Control Module..

Please help

 

I don't show a P0070 on my list. I do have P0068,P0071 and P0072. Here some information on the other code U1120.
