1. You must read the fault code to see what's the fault cos there are default modes when TC is still active others when not and 10 possible causes for 3 amigos even though hub and SVSs are the most common
2. Dont start to replace sensors randomly cos in most cases the problem is with the whole hub not with the sensor, you can check each sensor's resistance with multimeter(provided they are not the hardwired type) it must be between 950 - 1100 Ohm, if the resistance is good but you still get sensor related fault code it's due to a play in the reluctor ring so new hub is needed(which comes with sensr fitted)
