DTC P0715: Input Shaft (Mainshaft) Speed Sensor Circuit Malfunction (M/T Model): General Description

The input shaft (mainshaft) speed sensor is attached to the transmission housing to sense input shaft (mainshaft) revolutions. The engine control module (ECM) determines the vehicle speed according to the signal from the input shaft (mainshaft) speed sensor for the control units. If no signal from the input shaft (mainshaft) speed sensor is received for a set time, the ECM detects a malfunction and a DTC is stored.
