#46 SECONDARY THROTTLE SENSOR: when You have Traction control on a Q45 that means that your rear tires will grab in the rain or snow or what have you, but to do that the Traction computer relaizes that the rear tires are spinning faster than the front tires because of the wheel speed sensors on all four wheels so the TCU closes the throttle on the engine and (I am not totaly sure but it might apply the brakes too on the rear tires, there by wearing down the rear brakes) Thats why most dare devils leave it off in the summer or winter.

But the secondary throttle position sensor just tells the traction computer how open or closed the throttle is.

In short you might need another Secondary throttle postion sensor



The white circle is the main or first Throttle positon sensor, The red circle is where the secondary throttle postion sensor would be but not shown just look somewhere around there for it will be a little black box. There are just two screws holding on to it.

WHAT IS THE TCS SIGNAL: the TCS signal is the signal from the Transmission control unit to the ECU which tells the Engine control unit all the information that the ECU needs to work and run the car.

In short you might need a new TCU.

To find the parts you can try: http://car-part.com to find the nearist junk yard.

Orhttp://forums.nicoclub.com/zeroforum/172 and trust me you can trust them or us As Mike Goodwin (goody94q45) sent me great parts (The CD changer cable and the Q45 trunk logo for a great price)

Good luck
