DTC P0716 - INPUT/TURBINE SPEED SENSOR CIRCUIT RANGE/PERFORMANCE

OUTLINE OF DIAGNOSIS
Judge NG when the turbine speed signal is not transmitted for some reasons.

COMPONENT DESCRIPTION
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.
