My car has a tps code coming up. I beileve the code was po121 if I can remember. The car has traction control. When you first start the car up the traction control button will work properly and the light in the dash will be off, but after driving it for a few miles the traction control will cut off on it's own and light up the tcs light in the dash. When this happens you cannot turn it back on pushing the button. When you come to a complete stop after about 8 seconds or so the light will go back off and the button will work properly. I replaced the tps sensor with one off of another car and it did'nt fix the problem. The car seems to drive completly normal other thatn the tcs jumping on and off. With the tcs acting up while moving and being fine when stoped it kinda leads me to believe it could be a wheel sensor bad? Any imput would be greatly appreciated!

 

Anyone?

 

Could be a wheel sensor. There is one on each side, not sure how to tell if one is bad though.
