Eaton Gen 1 (AutoShift) Fault Code: 56 PID: PID 161 FMI: 2 Input Shaft Speed Sensor

Overview:
This code indicates an electrical problem in the input shaft speed sensor circuit. The signal from the sensor did not match the current operating conditions.

Detection:
A speed sensor is determined faulty when all the speed sensor readings are compared and one sensor is inconsistent.

Fallback:
This fault causes an In Place fallback. If the Input Shaft Speed Sensor fails before power-up, the transmission is unable to engage a gear and the fault code cannot be reproduced.

Required Tools:
1) Basic Hand Tools
2) Digital Volt/Ohm Meter
3) AutoSelect/AutoShift Troubleshooting Guide

Possible Causes:
1) Loose speed sensor
2) Contaminated sensor end
3) Damaged transmission harness
4) Malfunctioning input shaft speed sensor
5) Failed main drive gear
6) Malfunctioning transmission ECU
