I have a 2006 Saturn ion. The speedometer is not working and the car will not shift, I believe the car is in limp mode. The oss sensor is new and the code I am getting UO101. Any suggestions?
Hello, first it means the code tells you that there is lost of communication with the TCM ( traction control module ). Check all fuse link to that module an if everything is fine buy another module an let it be able to communicate first. That cat will never change because it needs to know the vehicle speed for it to change since it's automatic transmission..
