DTC P0716 INPUT/TURBINE SPEED SENSOR
CIRCUIT RANGE/PERFORMANCE
|
Judge NG when the turbine speed signal is
not transmitted for some reasons.
Torque converter turbine speed sensor (output
shaft speed sensor) is installed to the outside of transmission case.
This sensor detects the turbine speed of torque converter by the
peripheral speed of high clutch drum connected to input shaft. And
then it transmits the sine wave signal (32 pulses per rev.) to TCM.
TCM calculates the ratio of the input shaft speed to vehicle speed,
and then makes a judgment whether to shift or not.
