The input shaft speed sensor generates a pulsed signal of 0 5 volts. The pulsed signal frequency increases with an increase in the input shaft speed.
The PCM (terminal 111) continuously monitors the input shaft speed signal.
DESCRIPTIONS OF MONITOR METHODS
In 1st gear, if a difference between turbine revolution and that value calculated from output revolution equals or exceeds specified value, PCM judges that step-out in 1st gear has occurred.
