Descriptions Of Monitor Methods

<If open circuit occurs during test driving> If abruptly reduced output revolution is detected during test driving, and a difference between turbine revolution and that value calculated from output revolution equals or exceeds specified value, PCM judges that output shaft speed sensor has a failure.
<If open circuit occurs with vehicle stopped, and driving test is started> If there is no detection pulse from output shaft speed sensor (output rotation) even when engine revolution and turbine revolution both equal or exceed specified value, PCM judges that output shaft speed sensor has a failure.
