Problem in Input Shaft (Mainshaft) Speed Sensor Circuit (No Signal Input)
Problem in Input Shaft (Mainshaft) Speed Sensor Circuit (No Signal Input)
Description
If no pulses occur with the input shaft (mainshaft) rotating, the PCM detects a malfunction that may be caused by an open, a temporary open, or a short to ground. When the vehicle speed measured by the output shaft (countershaft) speed sensor is 13 mph (20 km h) or more, the vehicle speed measured by the input shaft (mainshaft) speed sensor is 1 mph (2 km h) or less for at least 10 seconds. NOTE: This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
Cause and Solution
Loose or poor connections at the PCM and input shaft (mainshaft) speed sensor connectors
Open in the wires between PCM connector terminals and ground (G101), or repair poor ground
Faulty or improperly installed Input Shaft (Mainshaft) Speed Sensor
PCM needs to be updated with the latest software
