DTC P0715 Input/ Turbine Speed Sensor Circuit MalfunctionDTC P0717 Input Speed Sensor Circuit No Signal
SYSTEM DESCRIPTION
This sensor detects the rotation speed of the turbine which shows the input revolution of transaxle. By comparing the input turbine speed signal (NT) with the counter gear speed sensor signal (NC), the TCM detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure according to various conditions, thus, providing smooth gear shift.
MONITOR DESCRIPTION
The NT terminal of the TCM detects a revolution signal from the speed sensor (NT) (input RPM). The TCM calculates a gearshift comparing the speed sensor (NT) with the speed sensor (NC).
While the vehicle is operating in 2nd, 3rd, 4th or 5th gear in the shift position of D, if the input shaft revolution is less than 300 rpm *1 although the output shaft revolution is more than 1,000 rpm *2, the TCM interprets this as a fault, illuminates the MIL and stores the DTC.
*1: Pulse is not output or is irregularly output.
*2: The vehicle speed is 31 mph (50 km/h) or more.

INSPECTION PROCEDURE
1. DATA LIST
NOTICE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty.
HINT: According to the DATA LIST displayed on the intelligent tester, you can read the value of switches, sensors, actuators and other items without removing any parts. Reading the DATA LIST as the first step in troubleshooting is one method to save labor time.
(a) Warm up the engine.
(b) Turn the engine switch off.
(c) Connect the intelligent tester together with the CAN VIM (Controller Area Network Vehicle Interface Module) to the DLC3.
(d) Turn the engine switch on (IG).
(e) Turn on the tester.
(f) Enter the following items: "DIAGNOSIS / OBD/MOBD / ECT / DATA LIST".
(g) According to the display on the tester, read "DATA LIST".
HINT:
^ SPD (NT) is always 0 while driving: Open or short in the sensor or circuit.
^ SPD (NT) is always more than 0 and less than 300 rpm while driving the vehicle at 31 mph (50 km/h) or more: Sensor trouble, improper installation, or intermittent connection trouble of the circuit.
