TPS is a signal to judge the amount of depressing accel and this is inputted into TCCU from engine ECM with PWM signal. Together with speed sensor signal ,TPS signal is a reference to decide torque distribution amount to front and rear wheels.
As related to TPS,this trouble code is set if TPS signal is out of range.
