P0716

P0716 - INPUT SPEED SENSOR (ISS) INTERMITTENT (L61)









The Input Speed Sensor (ISS) provides transaxle input speed to the PCM. The ISS is a Permanent Magnet (PM) generator. The sensor mounts into the transaxle case and maintains a slight air gap between the sensor and the drive sprocket. The PM generator produces an AC voltage as the drive sprocket rotor teeth pass through the sensor's magnetic field. The AC voltage level increases as the turbine shaft speed increases. The PCM converts the AC voltage into a digital signal. The PCM determines actual turbine speed using the digital signal. The PCM uses the input speed to calculate torque converter

DTC PARAMETERS
DTC P0716 will set if the PCM detects that input shaft speed (transmission ISS) has changed by more than 1300 rpm within 0.8 seconds when the following conditions have been met:
- Engine is running
- Vehicle speed is greater than 8 km/h (5 mph).
- TP sensor is greater than 15%
- No 1-2 shift solenoid, 2-3 shift solenoid, OSS sensor, TP sensor or P07 17 DTCs have been set.
P0716 is a (type B) DTC.

DIAGNOSTIC AIDS
Check wire routing for possible chafed wires.
