Basic error definition

Input Shaft (Mainshaft) Speed Sensor Intermittent Failure

Cause of DTC

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. The fluctuation of the vehicle speed measured by the input shaft (mainshaft) speed sensor in 10 milliseconds is 4 mph (6km h) or more, and it fluctuates at least six times within 500 milliseconds. NOTE: This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
